L-Proline

pyrrolidine-2-carboxylic acid

C5H9NO2 (115.0633)


Proline (Pro), also known as L-proline is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Proline is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Proline is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. Proline is sometimes called an imino acid, although the IUPAC definition of an imine requires a carbon-nitrogen double bond. Proline is a non-essential amino acid that is synthesized from glutamic acid. It is an essential component of collagen and is important for proper functioning of joints and tendons. Proline is derived from the amino acid L-glutamate in which glutamate-5-semialdehyde is first formed by glutamate 5-kinase and glutamate-5-semialdehyde dehydrogenase (which requires NADH or NADPH). This semialdehyde can then either spontaneously cyclize to form 1-pyrroline-5-carboxylic acid, which is reduced to proline by pyrroline-5-carboxylate reductase, or turned into ornithine by ornithine aminotransferase, followed by cyclization by ornithine cyclodeaminase to form proline. L-Proline has been found to act as a weak agonist of the glycine receptor and of both NMDA and non-NMDA ionotropic glutamate receptors. It has been proposed to be a potential endogenous excitotoxin/neurotoxin. Studies in rats have shown that when injected into the brain, proline non-selectively destroys pyramidal and granule cells (PMID: 3409032 ). Therefore, under certain conditions proline can act as a neurotoxin and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of proline are associated with at least five inborn errors of metabolism, including hyperprolinemia type I, hyperprolinemia type II, iminoglycinuria, prolinemia type II, and pyruvate carboxylase deficiency. People with hyperprolinemia type I often do not show any symptoms even though they have proline levels in their blood between 3 and 10 times the normal level. Some individuals with hyperprolinemia type I exhibit seizures, intellectual disability, or other neurological or psychiatric problems. Hyperprolinemia type II results in proline levels in the blood between 10 and 15 times higher than normal, and high levels of a related compound called pyrroline-5-carboxylate. Hyperprolinemia type II has signs and symptoms that vary in severity and is more likely than type I to involve seizures or intellectual disability. L-proline is pyrrolidine in which the pro-S hydrogen at position 2 is substituted by a carboxylic acid group. L-Proline is the only one of the twenty DNA-encoded amino acids which has a secondary amino group alpha to the carboxyl group. It is an essential component of collagen and is important for proper functioning of joints and tendons. It also helps maintain and strengthen heart muscles. It has a role as a micronutrient, a nutraceutical, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite and a member of compatible osmolytes. It is a glutamine family amino acid, a proteinogenic amino acid, a proline and a L-alpha-amino acid. It is a conjugate base of a L-prolinium. It is a conjugate acid of a L-prolinate. It is an enantiomer of a D-proline. It is a tautomer of a L-proline zwitterion. Proline is one of the twenty amino acids used in living organisms as the building blocks of proteins. Proline is sometimes called an imino acid, although the IUPAC definition of an imine requires a carbon-nitrogen double bond. Proline is a non-essential amino acid that is synthesized from glutamic acid. It is an essential component of collagen and is important for proper functioning of joints and tendons. L-Proline is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Proline is a cyclic, nonessential amino acid (actually, an imino acid) in humans (synthesized from glutamic acid and other amino acids), Proline is a constituent of many proteins. Found in high concentrations in collagen, proline constitutes almost a third of the residues. Collagen is the main supportive protein of skin, tendons, bones, and connective tissue and promotes their health and healing.

7-Methyl-3-methylene-1,6-octadiene, also known as beta-Myrcene or myrcene is an acyclic monoterpene. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes is known to occur mainly through the methyl-erythritol-phosphate (MEP) pathway in the plastids. beta-Myrcene is a significant component of the essential oil of several plants, including allspice, bay, cannabis, hops, houttuynia, lemon grass, mango, myrcia, verbena, west indian bay tree, and cardamom. It is also the main component of wild thyme, the leaves of which contain up to 40\\\\% by weight of myrcene. Industrially, it is produced mainly semi-synthetically from myrcia, from which it gets its name. Myrcene has been detected as a volatile component in cannabis plant samples (PMID:26657499 ) and its essential oils (PMID:6991645 ). beta-Myrcene is the most abundant monoterpene in Cannabis and it has analgesic, anti-inflammatory, antibiotic, and antimutagenic activities. beta-Myrcene is a flavouring agent and it is used in the perfumery industry. It has a pleasant odor but is rarely used directly. It is a key intermediate in the production of several fragrances such as menthol, citral, citronellol, citronellal, geraniol, nerol, and linalool. Myrcene, [liquid] appears as a yellow oily liquid with a pleasant odor. Flash point below 200 °F. Insoluble in water and less dense than water. Beta-myrcene is a monoterpene that is octa-1,6-diene bearing methylene and methyl substituents at positions 3 and 7 respectively. It has a role as a plant metabolite, an anti-inflammatory agent, an anabolic agent, a fragrance, a flavouring agent and a volatile oil component. Myrcene is a natural product found in Teucrium montanum, Xylopia aromatica, and other organisms with data available. 7-Methyl-3-methylene-1,6-octadiene is found in allspice. 7-Methyl-3-methylene-1,6-octadiene is found in many essential oils, e.g. hop oil. 7-Methyl-3-methylene-1,6-octadiene is a flavouring agent.
