Protocatechuic acid

3,4-dihydroxybenzoic acid

C7H6O4 (154.0266076)


Protocatechuic acid, also known as protocatechuate or 3,4-dihydroxybenzoate, belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. The enzyme protocatechuate 3,4-dioxygenase uses 3,4-dihydroxybenzoate and O2 to produce 3-carboxy-cis,cis-muconate. Protocatechuic acid is a drug. In the analogous hardening of the cockroach ootheca, the phenolic substance concerned is protocatechuic acid. Protocatechuic acid is a mild, balsamic, and phenolic tasting compound. Outside of the human body, protocatechuic acid is found, on average, in the highest concentration in a few different foods, such as garden onions, cocoa powders, and star anises and in a lower concentration in lentils, liquors, and red raspberries. Protocatechuic acid has also been detected, but not quantified in several different foods, such as cloud ear fungus, american pokeweeds, common mushrooms, fruits, and feijoa. This could make protocatechuic acid a potential biomarker for the consumption of these foods. It is also found in Allium cepa (17,540 ppm). It is a major metabolite of antioxidant polyphenols found in green tea. Similarly, PCA was reported to increase proliferation and inhibit apoptosis of neural stem cells. In vitro testing documented antioxidant and anti-inflammatory activity of PCA, while liver protection in vivo was measured by chemical markers and histological assessment. 3,4-dihydroxybenzoic acid, also known as protocatechuic acid or 4-carboxy-1,2-dihydroxybenzene, belongs to hydroxybenzoic acid derivatives class of compounds. Those are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. 3,4-dihydroxybenzoic acid is soluble (in water) and a weakly acidic compound (based on its pKa). 3,4-dihydroxybenzoic acid can be synthesized from benzoic acid. 3,4-dihydroxybenzoic acid is also a parent compound for other transformation products, including but not limited to, methyl 3,4-dihydroxybenzoate, ethyl 3,4-dihydroxybenzoate, and 1-(3,4-dihydroxybenzoyl)-beta-D-glucopyranose. 3,4-dihydroxybenzoic acid is a mild, balsamic, and phenolic tasting compound and can be found in a number of food items such as white mustard, grape wine, abalone, and asian pear, which makes 3,4-dihydroxybenzoic acid a potential biomarker for the consumption of these food products. 3,4-dihydroxybenzoic acid can be found primarily in blood, feces, and urine, as well as in human fibroblasts and testes tissues. 3,4-dihydroxybenzoic acid exists in all eukaryotes, ranging from yeast to humans. Protocatechuic acid (PCA) is a dihydroxybenzoic acid, a type of phenolic acid. It is a major metabolite of antioxidant polyphenols found in green tea. It has mixed effects on normal and cancer cells in in vitro and in vivo studies . 3,4-dihydroxybenzoic acid is a dihydroxybenzoic acid in which the hydroxy groups are located at positions 3 and 4.

Oleanolic acid is a pentacyclic triterpene, found in the non-glyceride fraction of olive pomace oil (Olive pomace oil, also known as "orujo" olive oil, is a blend of refined-pomace oil and virgin olive oil, fit for human consumption). Pentacyclic triterpenes are natural compounds which are widely distributed in plants. These natural products have been demonstrated to possess anti-inflammatory properties. Triterpenoids have been reported to possess antioxidant properties, since they prevent lipid peroxidation and suppress superoxide anion generation. The triterpenes have a history of medicinal use in many Asian countries. Oleanolic acid exhibits both pro- and anti-inflammatory properties depending on chemical structure and dose and may be useful in modulating the immune response; further studies are required to confirm the immunomodulatory behaviour of this triterpenoid, and characterise the mechanisms underlying the biphasic nature of some aspects of the inflammatory response. Oleanolic acid is a ubiquitous triterpenoid in plant kingdom, medicinal herbs, and is an integral part of the human diet. During the last decade over 700 research articles have been published on triterpenoids research, reflecting tremendous interest and progress in our understanding of these compounds. This included the isolation and purification of these tritepernoids from various plants and herbs, the chemical modifications to make more effective and water soluble derivatives, the pharmacological research on their beneficial effects, the toxicity studies, and the clinical use of these triterpenoids in various diseases including anticancer chemotherapies. (PMID:17292619, 15522132, 15994040). Oleanolic acid is a pentacyclic triterpenoid that is olean-12-en-28-oic acid substituted by a beta-hydroxy group at position 3. It has a role as a plant metabolite. It is a pentacyclic triterpenoid and a hydroxy monocarboxylic acid. It is a conjugate acid of an oleanolate. It derives from a hydride of an oleanane. Oleanolic acid is a natural product found in Ophiopogon japonicus, Freziera, and other organisms with data available. A pentacyclic triterpene that occurs widely in many PLANTS as the free acid or the aglycone for many SAPONINS. It is biosynthesized from lupane.

Stearic acid

1-Heptadecanecarboxylic acid

C18H36O2 (284.2715156)


Stearic acid, also known as stearate or N-octadecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, stearic acid is considered to be a fatty acid lipid molecule. Stearic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Stearic acid can be synthesized from octadecane. Stearic acid is also a parent compound for other transformation products, including but not limited to, 3-oxooctadecanoic acid, (9S,10S)-10-hydroxy-9-(phosphonooxy)octadecanoic acid, and 16-methyloctadecanoic acid. Stearic acid can be found in a number of food items such as green bell pepper, common oregano, ucuhuba, and babassu palm, which makes stearic acid a potential biomarker for the consumption of these food products. Stearic acid can be found primarily in most biofluids, including urine, feces, cerebrospinal fluid (CSF), and sweat, as well as throughout most human tissues. Stearic acid exists in all living species, ranging from bacteria to humans. In humans, stearic acid is involved in the plasmalogen synthesis. Stearic acid is also involved in mitochondrial beta-oxidation of long chain saturated fatty acids, which is a metabolic disorder. Moreover, stearic acid is found to be associated with schizophrenia. Stearic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Stearic acid ( STEER-ik, stee-ARR-ik) is a saturated fatty acid with an 18-carbon chain and has the IUPAC name octadecanoic acid. It is a waxy solid and its chemical formula is C17H35CO2H. Its name comes from the Greek word στέαρ "stéar", which means tallow. The salts and esters of stearic acid are called stearates. As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. The triglyceride derived from three molecules of stearic acid is called stearin . Stearic acid, also known as octadecanoic acid or C18:0, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Stearic acid (its ester is called stearate) is a saturated fatty acid that has 18 carbons and is therefore a very hydrophobic molecule that is practically insoluble in water. It exists as a waxy solid. In terms of its biosynthesis, stearic acid is produced from carbohydrates via the fatty acid synthesis machinery wherein acetyl-CoA contributes two-carbon building blocks, up to the 16-carbon palmitate, via the enzyme complex fatty acid synthase (FA synthase), at which point a fatty acid elongase is needed to further lengthen it. After synthesis, there are a variety of reactions it may undergo, including desaturation to oleate via stearoyl-CoA desaturase (PMID: 16477801). Stearic acid is found in all living organisms ranging from bacteria to plants to animals. It is one of the useful types of saturated fatty acids that comes from many animal and vegetable fats and oils. For example, it is a component of cocoa butter and shea butter. It is used as a food additive, in cleaning and personal care products, and in lubricants. Its name comes from the Greek word stear, which means ‚Äòtallow‚Äô or ‚Äòhard fat‚Äô. Stearic acid is a long chain dietary saturated fatty acid which exists in many animal and vegetable fats and oils. Stearic acid is a long chain dietary saturated fatty acid which exists in many animal and vegetable fats and oils.
