| Description | (±)-Erythro-Isoleucine, also known as (+/-)-isoleucine or (+/-)-erythro-form, belongs to the class of organic compounds known as isoleucine and derivatives. Isoleucine and derivatives are compounds containing isoleucine or a derivative thereof resulting from reaction of isoleucine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom (±)-erythro-Isoleucine is a very strong basic compound (based on its pKa) (±)-erythro-Isoleucine is a bitter and odorless tasting compound. Outside of the human body, (±)-erythro-Isoleucine is found, on average, in the highest concentration within a few different foods, such as caseins, milk (cow), and beluga whales and in a lower concentration in garden onions, other soy products, and sweet cherries (±)-erythro-Isoleucine has also been detected, but not quantified in, several different foods, such as soursops, oxheart cabbages, alpine sweetvetchs, mugworts, and roselles. This could make (±)-erythro-isoleucine a potential biomarker for the consumption of these foods. The ratio of leucine to other BCAA is greatest in pork, where leucine is 7 to 8 g and the other BCAA together are only 3 to 4 g (http://Www.Dcnutrition.Com). The BCAA are not without side effects. Valine, in particular, has been established as a useful supplemental therapy to the ailing liver. Branched-chain amino acids (BCAA) are essential amino acids whose carbon structure is marked by a branch point. BCAA supplementation as therapy, both oral and intravenous, in human health and disease holds great promise. lisoleucine is found in Antirrhinum majus, Castanea sativa, Catha edulis, Claviceps purpurea, Colchicum trigynum, Daphnia magna, Glycine max, Pogostemon cablin, Puccinia graminis, Stellaria media, Vicia sativa and Viscum album. lisoleucine was first documented in 2000 (PMID: 10944265). Aromatic amino acids (AAA)-tyrosine, tryptophan, and phenylalanine (as well as methionine) are increased in these conditions. |
