D-Alanyl-D-alanine

(2R)-2-[(2R)-2-aminopropanamido]propanoic acid

C6H12N2O3 (160.0848)


The ATP-dependent carboxylate-amine/thiol ligase superfamily is known to contain enzymes catalyzing the formation of various types of peptide, one of which is d-alanyl-d-alanine.(PMID: 16030213). The glycopeptide antibiotic vancomycin acts by binding to the D-alanyl-D-alanine terminus of the cell wall precursor lipid II in the cytoplasmic membrane.(PMID: 17418637). D-alanine-D-alanine ligase from Thermotoga maritima ATCC 43589 (TmDdl) was a useful biocatalyst for synthesizing D-amino acid dipeptides.D-Alanine-D-alanine ligase (Ddl) catalyzes the biosynthesis of an essential bacterial peptidoglycan precursor D-alanyl-D-alanine and it represents an important target for development of new antibacterial drugs. (PMID: 17267218). D-Alanyl-D-alanine is a microbial metabolite. Alanyl-alanine, also known as ala-ala or A-a dipeptide, is a member of the class of compounds known as dipeptides. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Alanyl-alanine is soluble (in water) and a weakly acidic compound (based on its pKa). Alanyl-alanine can be found in chives, which makes alanyl-alanine a potential biomarker for the consumption of this food product. Alanyl-alanine can be found primarily in feces. Alanyl-alanine exists in all living organisms, ranging from bacteria to humans. Acquisition and generation of the data is financially supported in part by CREST/JST. D-Ala-D-Ala constitutes the terminus of the peptide part of the peptidoglycan monomer unit and is involved in the transpeptidation reaction as the substrate. D-Ala-D-Ala is catalyzed by D-Alanine-D-Alanine ligase. D-Ala-D-Ala is a bacterial endogenous metabolite[1][2].

   

Cefazolin

(6R,7R)-3-{[(5-methyl-1,3,4-thiadiazol-2-yl)sulfanyl]methyl}-8-oxo-7-[2-(1H-1,2,3,4-tetrazol-1-yl)acetamido]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid

C14H14N8O4S3 (454.03)


Cefazolin is only found in individuals that have used or taken this drug. It is a semisynthetic cephalosporin analog with broad-spectrum antibiotic action due to inhibition of bacterial cell wall synthesis. It attains high serum levels and is excreted quickly via the urine. [PubChem]In vitro tests demonstrate that the bactericidal action of cephalosporins results from inhibition of cell wall synthesis. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins.

L-Lactic acid

1-Hydroxyethane 1-carboxylic acid

C3H6O3 (90.0317)


Lactic acid is an organic acid. It is a chiral molecule, consisting of two optical isomers, L-lactic acid and D-lactic acid, with the L-isomer being the most common in living organisms. Lactic acid plays a role in several biochemical processes and is produced in the muscles during intense activity. In animals, L-lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase (LDH) in a process of fermentation during normal metabolism and exercise. It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal. This is governed by a number of factors, including monocarboxylate transporters, lactate concentration, the isoform of LDH, and oxidative capacity of tissues. The concentration of blood lactate is usually 1-2 mmol/L at rest, but can rise to over 20 mmol/L during intense exertion. There are some indications that lactate, and not glucose, is preferentially metabolized by neurons in the brain of several mammalian species, including mice, rats, and humans. Glial cells, using the lactate shuttle, are responsible for transforming glucose into lactate, and for providing lactate to the neurons. Lactate measurement in critically ill patients has been traditionally used to stratify patients with poor outcomes. However, plasma lactate levels are the result of a finely tuned interplay of factors that affect the balance between its production and its clearance. When the oxygen supply does not match its consumption, organisms adapt in many different ways, up to the point when energy failure occurs. Lactate, being part of the adaptive response, may then be used to assess the severity of the supply/demand imbalance. In such a scenario, the time to intervention becomes relevant: early and effective treatment may allow tissues and cells to revert to a normal state, as long as the oxygen machinery (i.e. mitochondria) is intact. Conversely, once the mitochondria are deranged, energy failure occurs even in the presence of normoxia. The lactate increase in critically ill patients may, therefore, be viewed as an early marker of a potentially reversible state (PMID: 16356243). When present in sufficiently high levels, lactic acid can act as an oncometabolite, an immunosuppressant, an acidogen, and a metabotoxin. An oncometabolite is a compound that promotes tumor growth and survival. An immunosuppressant reduces or arrests the activity of the immune system. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of lactic acid are associated with at least a dozen inborn errors of metabolism, including 2-methyl-3-hydroxybutyryl CoA dehydrogenase deficiency, biotinidase deficiency, fructose-1,6-diphosphatase deficiency, glycogen storage disease type 1A (GSD1A) or Von Gierke disease, glycogenosis type IB, glycogenosis type IC, glycogenosis type VI, Hers disease, lactic acidemia, Leigh syndrome, methylmalonate semialdehyde dehydrogenase deficiency, pyruvate decarboxylase E1 component deficiency, pyruvate dehydrogenase complex deficiency, pyruvate dehydrogenase deficiency, and short chain acyl CoA dehydrogenase deficiency (SCAD deficiency). Locally high concentrations of lactic acid or lactate are found near many tumors due to the upregulation of lactate dehydrogenase (PMID: 15279558). Lactic acid produced by tumors through aerobic glycolysis acts as an immunosuppressant and tumor promoter (PMID: 23729358). Indeed, lactic acid has been found to be a key player or regulator in the development and malignant progression of a variety of cancers (PMID: 22084445). A number of studies have demonstrated that malignant transformation is associated with an increase in aerobic cellular lactate excretion. Lactate concentrations in various carcinomas (e.g. uterine cervix, head and neck, colorectal regi... Occurs in the juice of muscular tissue, bile etc. Flavour ingredient, food antioxidant.

Acetoin

1-Hydroxyethyl methyl ketone

C4H8O2 (88.0524)


Acetoin, also known as dimethylketol or 2,3-butanolone, belongs to the class of organic compounds known as acyloins. These are organic compounds containing an alpha hydroxy ketone. Acyloins are formally derived from reductive coupling of carboxylic acyl groups. Thus, acetoin is considered to be an oxygenated hydrocarbon lipid molecule. Acetoin is used as an external energy store by a number of fermentive bacteria. Acetoin, along with diacetyl, is one of the compounds giving butter its characteristic flavor. Acetoin is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Acetoin is used as a food flavoring (in baked goods) and a fragrance. Acetoin is a sweet, buttery, and creamy tasting compound. Outside of the human body, Acetoin has been detected, but not quantified in several different foods, such as cocoa and cocoa products, evergreen blackberries, orange bell peppers, tortilla chips, and pomes. This could make acetoin a potential biomarker for the consumption of these foods. Constituent of beer, wine, fresh or cooked apple, fresh or cooked leak, corn, honey, cocoa, butter, cheeses, roasted coffee and other foodstuffs. Acetoin, with regard to humans, has been found to be associated with several diseases such as eosinophilic esophagitis and ulcerative colitis; acetoin has also been linked to the inborn metabolic disorder celiac disease. Acetoin is a colorless or pale yellow to green yellow liquid with a pleasant, buttery odor. It can be found in apples, butter, yogurt, asparagus, black currants, blackberry, wheat, broccoli, brussels sprouts, cantaloupe. Constituent of beer, wine, fresh or cooked apple, fresh or cooked leak, corn, honey, cocoa, butter, cheeses, roasted coffee and other foodstuffs. Flavouring ingredient. [DFC]
