Azelaic acid

nonanedioic acid

C9H16O4 (188.1049)


Nonanedioic acid is an alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. It has a role as an antibacterial agent, an antineoplastic agent, a dermatologic drug and a plant metabolite. It is a dicarboxylic fatty acid and an alpha,omega-dicarboxylic acid. It is a conjugate acid of an azelaate(2-) and an azelaate. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley. It is also produced by Malassezia furfur, also known as Pityrosporum ovale, which is a species of fungus that is normally found on human skin. Azelaic acid is effective against a number of skin conditions, such as mild to moderate acne, when applied topically in a cream formulation of 20\\\\\%. It works in part by stopping the growth of skin bacteria that cause acne, and by keeping skin pores clear. Azelaic acids antimicrobial action may be attributable to inhibition of microbial cellular protein synthesis. Azelaic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). The physiologic effect of azelaic acid is by means of Decreased Protein Synthesis, and Decreased Sebaceous Gland Activity. Azelaic Acid is a naturally occurring dicarboxylic acid produced by Malassezia furfur and found in whole grain cereals, rye, barley and animal products. Azelaic acid possesses antibacterial, keratolytic, comedolytic, and anti-oxidant activity. Azelaic acid is bactericidal against Proprionibacterium acnes and Staphylococcus epidermidis due to its inhibitory effect on the synthesis of microbial cellular proteins. Azelaic acid exerts its keratolytic and comedolytic effects by reducing the thickness of the stratum corneum and decreasing the number of keratohyalin granules by reducing the amount and distribution of filaggrin in epidermal layers. Azelaic acid also possesses a direct anti-inflammatory effect due to its scavenger activity of free oxygen radical. This drug is used topically to reduce inflammation associated with acne and rosacea. Azelaic acid is a saturated dicarboxylic acid found naturally in wheat, rye, and barley. It is a natural substance that is produced by Malassezia furfur (also known as Pityrosporum ovale), a yeast that lives on normal skin.

Azelaic acids antimicrobial action may be attributable to inhibition of microbial cellular protein synthesis. See also: Azelaic acid; niacinamide (component of) ... View More ... Azelaic acid (AZA) is a naturally occurring saturated nine-carbon dicarboxylic acid (COOH (CH2)7-COOH). It possesses a variety of biological actions both in vitro and in vivo. Interest in the biological activity of AZA arose originally out of studies of skin surface lipids and the pathogenesis of hypochromia in pityriasis versicolor infection. Later, it was shown that Pityrosporum can oxidize unsaturated fatty acids to C8-C12 dicarboxylic acids that are cornpetitive inhibitors of tyrosinase in vitro. Azelaic acid was chosen for further investigation and development of a new topical drug for treating hyperpigmentary disorders for the following reasons: it possesses a middle-range of antityrosinase activity, is inexpensive, and more soluble to be incorporated into a base cream than other dicarboxylic acids. Azelaic acid is another option for the topical treatment of mild to moderate inflammatory acne vulgaris. It offers effectiveness similar to that of other agents without the systemic side effects of oral antibiotics or the allergic sensitization of topical benzoyl peroxide and with less irritation than tretinoin. Azelaic acid is less expensive than certain other prescription acne preparations, but it is much more expensive than nonprescription benzoyl peroxide preparations. Whether it is safe and effective when used in combination with other agents is not known. (PMID: 7737781, 8961845). An alpha,omega-dicarboxylic acid that is heptane substituted at positions 1 and 7 by carboxy groups. Plants biology In plants, azelaic acid serves as a "distress flare" involved in defense responses after infection.[7] It serves as a signal that induces the accumulation of salicylic acid, an important component of a plant's defensive response.[8] Human biology The mechanism of action in humans is thought to be through the inhibition of hyperactive protease activity that converts cathelicidin into the antimicrobial skin peptide LL-37.[9] Polymers and related materials Esters of this dicarboxylic acid find applications in lubrication and plasticizers. In lubricant industries it is used as a thickening agent in lithium complex grease. With hexamethylenediamine, azelaic acid forms Nylon-6,9, which finds specialized uses as a plastic.[4] Medical Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne.[10][11] It belongs to a class of medication called dicarboxylic acids. It works by killing acne bacteria that infect skin pores. It also decreases the production of keratin, which is a natural substance that promotes the growth[clarification needed] of acne bacteria.[12] Azelaic acid is also used as a topical gel treatment for rosacea, due to its ability to reduce inflammation.[11] It clears the bumps and swelling caused by rosacea. In topical pharmaceutical preparations and scientific research AzA is typically used in concentrations between 15\\\% and 20\\\% but some research demonstrates that in certain vehicle formulations the pharmaceutical effects of 10\\\% Azelaic acid has the potential to be fully comparable to that of some 20\\\% creams.[13] Acne treatment Azelaic acid is effective for mild to moderate acne when applied topically at a 15\\\%-20\\\% concentration.[14][15][16][17] In patients with moderate acne, twice daily application over 3 months of 20\\\% AzA significantly reduced the number of comedones, papules, and pustules;[18][19] at this strength, it’s considered to be as effective as benzoyl peroxide 5\\\%, tretinoin 0.05\\\%, erythromycin 2\\\%, and oral tetracycline at 500 mg-1000 mg.[20][21] In a comparative review of effects of topical AzA, Salicylic acid, Nicotinamide, Sulfur, Zinc, and alpha-hydroxy acid, AzA had more high-quality evidence of effectiveness than the rest.[22] Results can be expected after 4 weeks of twice-daily treatment. The effectiveness of long term use is unclear, but it’s been recommended that AzA be used for at least 6 months continuously for maintenance.[20] Whitening agent Azelaic acid is used for treatment of skin pigmentation, including melasma and postinflammatory hyperpigmentation, particularly in those with darker skin types. It has been recommended as an alternative to hydroquinone.[23] As a tyrosinase inhibitor,[5] azelaic acid reduces synthesis of melanin.[24] According to one report in 1988, azelaic acid in combination with zinc sulfate in vitro was found to be a potent (90\\\% inhibition) 5α-reductase inhibitor, similar to the hair loss drugs finasteride and dutasteride.[25] In vitro research during mid-1980s evaluating azelaic acid's depigmenting (whitening) capability concluded it is effective (cytotoxic to melanocytes) at only high concentrations.[26] A 1996 review claimed 20\\\% AzA is as potent as 4\\\% hydroquinone after a period of application of three months without the latter's adverse effects and even more effective if applied along with tretinoin for the same period of time.[27][19] Azelaic acid is a nine-carbon dicarboxylic acid. Azelaic acid has antimicrobial activity against Propionibacterium acnes and Staphylococcus epidermidis through inhibition of microbial cellular prorein synthesis. Azelaic acid has hypopigmentation action resulting from its ability to scavenge free radicals[1][2]. Azelaic acid is a nine-carbon dicarboxylic acid.

3-Hydroxybutyric acid

(R)-(-)-beta-Hydroxybutyric acid

C4H8O3 (104.0473)


3-Hydroxybutyric acid (CAS: 300-85-6), also known as beta-hydroxybutanoic acid, is a typical partial-degradation product of branched-chain amino acids (primarily valine) released from muscle for hepatic and renal gluconeogenesis. This acid is metabolized by 3-hydroxybutyrate dehydrogenase (catalyzes the oxidation of 3-hydroxybutyrate to form acetoacetate, using NAD+ as an electron acceptor). The enzyme functions in nervous tissues and muscles, enabling the use of circulating hydroxybutyrate as a fuel. In the liver mitochondrial matrix, the enzyme can also catalyze the reverse reaction, a step in ketogenesis. 3-Hydroxybutyric acid is a chiral compound having two enantiomers, D-3-hydroxybutyric acid and L-3-hydroxybutyric acid, and is a ketone body. Like the other ketone bodies (acetoacetate and acetone), levels of 3-hydroxybutyrate in blood and urine are raised in ketosis. In humans, 3-hydroxybutyrate is synthesized in the liver from acetyl-CoA and can be used as an energy source by the brain when blood glucose is low. Blood levels of 3-hydroxybutyric acid levels may be monitored in diabetic patients to look for diabetic ketoacidosis. Persistent mild hyperketonemia is a common finding in newborns. Ketone bodies serve as an indispensable source of energy for extrahepatic tissues, especially the brain and lung of developing mammals. Another important function of ketone bodies is to provide acetoacetyl-CoA and acetyl-CoA for the synthesis of cholesterol, fatty acids, and complex lipids. During the early postnatal period, acetoacetate (AcAc) and beta-hydroxybutyrate are preferred over glucose as substrates for the synthesis of phospholipids and sphingolipids in accord with requirements for brain growth and myelination. Thus, during the first two weeks of postnatal development, when the accumulation of cholesterol and phospholipids accelerates, the proportion of ketone bodies incorporated into these lipids increases. On the other hand, an increased proportion of ketone bodies is utilized for cerebroside synthesis during the period of active myelination. In the lung, AcAc serves better than glucose as a precursor for the synthesis of lung phospholipids. The synthesized lipids, particularly dipalmitoylphosphatidylcholine, are incorporated into surfactant, and thus have a potential role in supplying adequate surfactant lipids to maintain lung function during the early days of life (PMID: 3884391). 3-Hydroxybutyric acid is found to be associated with fumarase deficiency and medium-chain acyl-CoA dehydrogenase deficiency, which are inborn errors of metabolism. 3-Hydroxybutyric acid is a metabolite of Alcaligenes and can be produced from plastic metabolization or incorporated into polymers, depending on the species (PMID: 7646009, 18615882). (R)-3-Hydroxybutyric acid is a butyric acid substituted with a hydroxyl group in the beta or 3 position. It is involved in the synthesis and degradation of ketone bodies.

N-alpha-acetylornithine

(2S)-5-Amino-2-acetamidopentanoic acid

C7H14N2O3 (174.1004)


N2-Acetylornithine, also known as N(alpha)-acetylornithine, belongs to the class of organic compounds known as N-acyl-L-alpha-amino acids. These are N-acylated alpha-amino acids which have the L-configuration of the alpha-carbon atom. N-Acetylornithine is a minor component of the deproteinized blood plasma of human blood. Human blood plasma contains a variable amount of acetylornithine, averaging 1.1 +/- 0.4 umol/L (range 0.8-0.2 umol/L). Urine contains a very small amount of acetylornithine, approximately 1 nmol/mg creatinine (1 umol/day) (PMID:508804).

N-Acetyltryptophan

(2S)-2-[(1-hydroxyethylidene)amino]-3-(1H-indol-3-yl)propanoic acid

C13H14N2O3 (246.1004)


N-Acetyl-L-tryptophan or N-Acetyltryptophan, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetyltryptophan can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetyltryptophan is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-tryptophan. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\\% of all human proteins and 68\\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetyltryptophan can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free tryptophan can also occur. Many N-acetylamino acids, including N-acetyltryptophan are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557). N-Acetyltryptophan has also been used as a protein stabilizer. It prevents protein molecules from oxidative degradation by scavenging oxygen dissolved in protein solutions (PMID: 21903216 ). N-Acetyltryptophan has been identified as a catabolite of tryptophan generated by the gut microbiota. After absorption through the intestinal epithelium, tryptophan catabolites enter the bloodstream and are later excreted in the urine (PMID: 28916042). N-Acetyltryptophan is an inhibitor of cytochrome c release and an antagonist of the neurokinin 1 receptor (NK-1R). These inhibitory effects are thought have a useful role in neuroprotection. For instance, in mouse models of amyotrophic lateral sclerosis (ALS) the administration of N-Acetyltryptophan has been shown delay disease onset, extend survival, and ameliorate deterioration in motor performance ALS transgenic mice (PMID: 25986728). N-acetyltryptophan has been shown to significantly reduce blood-brain barrier permeability and improve functional outcome in rat models of traumatic brain injury (PMID: 29256408). N-Acetyltryptophan has also been shown to have a role in preventing hepatic ischemia-reperfusion injury. This is thought to occur through de-activation of the RIP2/caspase/IL-1beta signaling pathway (PMID: 31184936).

C18H32O16 (504.169)


Maltotriose is a trisaccharide (three-part sugar) consisting of three glucose molecules linked with α-1,4 glycosidic bonds. It is most commonly produced by the digestive enzyme alpha-amylase (a common enzyme in human saliva) on amylose in starch. The creation of both maltotriose and maltose during this process is due to the random manner in which alpha amylase hydrolyses α-1,4 glycosidic bonds. It is the shortest chain oligosaccharide that can be classified as maltodextrin. Maltotriose belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Maltotriose is a common oligosaccharide metabolite found in human urine after maltose ingestion or infusion (PMID:6645121). Maltotriose is increased in glycogen storage disease II (OMIM: 232300) due to a mutation of the enzyme alpha-1,4-glucosidase (EC 3.2.1.20) (PMID:4286143). Constituent of corn syrup.

Caproic acid

Hexanoic acid, sodium salt, 1-(11)C-labeled

C6H12O2 (116.0837)


Caproic acid, also known as hexanoic acid or C6:0, is a medium-chain fatty acid. Medium-chain fatty acids (MCFA) are fatty acids with aliphatic tails of 6 to 12 carbons, which can form medium-chain triglycerides. Caproic acid is a colourless oily liquid that smells like cheese with an overlying waxy or barnyard odor like that of goats or other barnyard animals. Its name comes from the Latin word capra, meaning "goat". Two other fatty acids are named after goats: caprylic acid (C8) and capric acid (C10). Along with caproic acid, they account for 15\\% of the fat in goats milk. Caproic acid is a fatty acid found naturally in various animal fats and oils. While generally more abundant in animals, caproic acid is found in all organisms ranging from bacteria to plants to animals. Caproic acid is one of the chemicals that gives the decomposing fleshy seed coat of the ginkgo fruit its characteristic unpleasant odor. It is also one of the components of vanilla and cheese. Industrially, the primary use of caproic acid is in the manufacture of its esters for use as artificial flavors and in the manufacture of hexyl derivatives, such as hexylphenols. Caproic acid has been associated with medium chain acyl-CoA dehydrogenase deficiency, which is an inborn error of metabolism. As a relatively volatile organic compound, caproic acid has been identified as a fecal biomarker of Clostridium difficile infection (PMID: 30986230). Present in apple, wine grapes, butter, licorice and cheeses, e.g. blue cheeses, Cheddar cheese, Swiss cheese, feta cheese, gruyere de comte cheese, etcand is) also present in a few essential oils and fruital aromas.

C17H17N3O6S2 (423.0559)


Cephapirin is an injectable, first-generation cephalosporin antibiotic that has a wide spectrum of activity against gram-positive and gram-negative organisms. The bactericidal activity of cephapirin results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Cephapirin is more resistant to beta-lactamases than the penicillins, and therefore is effective against staphylococci, with the exception of methicillin-resistant staphylococci. Cephapirin is FDA approved for use in food-producing animals, especially dairy cattle. Cephapirin is used for the treatment of mastitis in cows. Production for use in humans has been discontinued in the United States. It is marketed under the trade name Cefadyl. Active against gram-positive and -negative bacteria (vet. use).

Lomefloxacin is only found in individuals that have used or taken this drug. It is a fluoroquinolone antibiotic, used to treat bacterial infections including bronchitis and urinary tract infections. It is also used to prevent urinary tract infections prior to surgery.Lomefloxacin is a bactericidal fluoroquinolone agent with activity against a wide range of gram-negative and gram-positive organisms. The bactericidal action of lomefloxacin results from interference with the activity of the bacterial enzymes DNA gyrase and topoisomerase IV, which are needed for the transcription and replication of bacterial DNA. DNA gyrase appears to be the primary quinolone target for gram-negative bacteria. Topoisomerase IV appears to be the preferential target in gram-positive organisms. Interference with these two topoisomerases results in strand breakage of the bacterial chromosome, supercoiling, and resealing. As a result DNA replication and transcription is inhibited.

Isobutyric acid

Isobutyric acid, sodium salt, 14C-labeled

C4H8O2 (88.0524)


Isobutyric acid is a carboxylic or short chain fatty acid with characteristic sweat-like smell. Small amount of isobutyrate is generated via microbial (gut) metabolism. Small amounts may also be found in certain foods or fermented beverages. There is anosmia (genetic inability to smell) for the odor of isobutyric acid with a frequency of about 2.5\\%. (OMIM 207000). Isobutyric acid is slightly soluble in water but much more soluble in ethanol, ether and organic solvents. Isobutyric acid can affect people if breathed in and may be absorbed through the skin. Contact can irritate and burn the skin and eyes. Breathing Isobutyric acid can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. Present in apple, morello cherry, guava fruit, wine grapes, pineapple, crispbread, other breads, cheeses, wines, scallop and several essential oils, e.g. Roman chamomile.

Stearidonic acid

(6Z,9Z,12Z,15Z)-Octadeca-6,9,12,15-tetraenoic acid

C18H28O2 (276.2089)


Steridonic acid, also known as (6z,9z,12z,15z)-octadecatetraenoic acid or stearidonate, belongs to lineolic acids and derivatives class of compounds. Those are derivatives of lineolic acid. Lineolic acid is a polyunsaturated omega-6 18 carbon long fatty acid, with two CC double bonds at the 9- and 12-positions. Thus, steridonic acid is considered to be a fatty acid lipid molecule. Steridonic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Steridonic acid can be found in borage, which makes steridonic acid a potential biomarker for the consumption of this food product. Steridonic acid can be found primarily in blood and feces. In humans, steridonic acid is involved in the alpha linolenic acid and linoleic acid metabolism. Stearidonic acid is found in dietary plant oils which are metabolized to longer-chain, more unsaturated (n-3) PUFA. These oils appear to possess hypotriglyceridemic properties typically associated with fish oils.(PMID: 15173404). Stearidonic acid may be used as a precursor to increase the EPA content of human lipids and that combinations of gamma-linolenic acid and stearidonic acid eicosapentaenoic acid can be used to manipulate the fatty acid compositions of lipid pools in subtle ways. Such effects may offer new strategies for manipulation of cell composition in order to influence cellular responses and functions in desirable ways. (PMID: 15120716).

   

2-Hydroxybutyric acid

DL-alpha-Hydroxybutyric acid barium salt

C4H8O3 (104.0473)


2-Hydroxybutyric acid (CAS: 600-15-7), also known as alpha-hydroxybutyrate, is an organic acid derived from alpha-ketobutyrate. alpha-Ketobutyrate is produced by amino acid catabolism (threonine and methionine) and glutathione anabolism (cysteine formation pathway) and is metabolized into propionyl-CoA and carbon dioxide (PMID: 20526369). 2-Hydroxybutyric acid is formed as a byproduct from the formation of alpha-ketobutyrate via a reaction catalyzed by lactate dehydrogenase (LDH) or alpha-hydroxybutyrate dehydrogenase (alphaHBDH). alpha-Hydroxybutyric acid is primarily produced in mammalian hepatic tissues that catabolize L-threonine or synthesize glutathione. Oxidative stress or detoxification of xenobiotics in the liver can dramatically increase the rate of hepatic glutathione synthesis. Under such metabolic stress conditions, supplies of L-cysteine for glutathione synthesis become limiting, so homocysteine is diverted from the transmethylation pathway (which forms methionine) into the transsulfuration pathway (which forms cystathionine). alpha-Ketobutyrate is released as a byproduct when cystathionine is cleaved into cysteine that is incorporated into glutathione. Chronic shifts in the rate of glutathione synthesis may be reflected by urinary excretion of 2-hydroxybutyrate. 2-Hydroxybutyrate is an early marker for both insulin resistance and impaired glucose regulation that appears to arise due to increased lipid oxidation and oxidative stress (PMID: 20526369). 2-Hydroxybutyric acid is often found in the urine of patients suffering from lactic acidosis and ketoacidosis. 2-Hydroxybutyric acid generally appears at high concentrations in situations related to deficient energy metabolism (e.g. birth asphyxia) and also in inherited metabolic diseases affecting the central nervous system during neonatal development, such as "cerebral" lactic acidosis, glutaric aciduria type II, dihydrolipoyl dehydrogenase (E3) deficiency, and propionic acidemia. More recently it has been noted that elevated levels of alpha-hydroxybutyrate in the plasma is a good marker for early-stage type II diabetes (PMID: 19166731). It was concluded from studies done in the mid-1970s that an increased NADH2/NAD ratio was the most important factor for the production of 2-hydroxybutyric acid (PMID: 168632). 2-Hydroxybutyric acid is an organic acid that is involved in propanoate metabolism. It is produced in mammalian tissues (principaly hepatic) that catabolize L-threonine or synthesize glutathione. Oxidative stress or detoxification demands can dramatically increase the rate of hepatic glutathione synthesis. Under such metabolic stress conditions, supplies of L-cysteine for glutathione synthesis become limiting, so homocysteine is diverted from the transmethylation pathway forming methionine into the transsulfuration pathway forming cystathionine. 2-Hydroxybutyrate is released as a by-product when cystathionine is cleaved to cysteine that is incorporated into glutathione. 2-Hydroxybutyric acid is often found in the urine of patients suffering from lactic acidosis and ketoacidosis. 2-Hydroxybutyric acid generally appears at high concentrations in situations related to deficient energy metabolism (e.g., birth asphyxia) and also in inherited metabolic diseases affecting the central nervous system during neonatal development, such as "cerebral" lactic acidosis, glutaric aciduria type II, dihydrolipoyl dehydrogenase (E3) deficiency, and propionic acidemia.

Diethylcarbamazine is only found in individuals that have used or taken this drug. It is an anthelmintic used primarily as the citrate in the treatment of filariasis, particularly infestations with Wucheria bancrofti or Loa loa. [PubChem]The mechanism of action of diethylcarbamazine is thought to involve sensitizing the microfilariae to phagocytosis. One study showed that diethylcarbamazines activity against Brugia malayi microfilariae is dependent on inducible nitric-oxide synthase and the cyclooxygenase pathway. It confirmed the important role of the arachidonic acid metabolic pathway in diethylcarbamazines mechanism of action in vivo and showes that in addition to its effects on the 5-lipoxygenase pathway, it targets the cyclooxygenase pathway and COX-1.

CE(16:0), also known as cholesteryl palmitic acid, is a cholesteryl ester. A cholesteryl ester is an ester of cholesterol. Fatty acid esters of cholesterol constitute about two-thirds of the cholesterol in the plasma. Cholesterol is a sterol (a combination of steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The accumulation of cholesterol esters in the arterial intima (the innermost layer of an artery, in direct contact with the flowing blood) is a characteristic feature of atherosclerosis. Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part to the deposition of lipoproteins (plasma proteins that carry cholesterol and triglycerides).

Lipid A is a lipid component of an endotoxin held responsible for toxicity of Gram-negative bacteria. It is the innermost of the three regions of the lipopolysaccharide (LPS, also called endotoxin) molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane. While its toxic effects can be damaging, the sensing of lipid A by the human immune system may also be critical for the onset of immune responses to Gram-negative infection, and for the subsequent successful fight against the infection. Many of the immune activating abilities of LPS can be attributed to the lipid A unit. It is a very potent stimulant of the immune system, activating cells (for example, monocytes or macrophages) at picogram per milliliter quantities.
