L-알라닌 C화학적 특성, 용도, 생산
개요
L-Alanine is a non-essential amino acid. It is produced by direct β-decarboxylation of L-aspartate by L-aspartate β-decarboxylase or transamination of pyruvate in the glucose-alanine cycle and is a precursor for gluconeogenesis. Dysregulation of L-alanine metabolism is associated with various disease states, including diabetes, metabolic syndrome, ketotic hypoglycemia, and acquired acute lactic acidosis.화학적 성질
White crystalline powder출처
Natural constituent of protein in plants and animals; found in apple, beef, carob, pea, soybean, wine and zucchini용도
L-Alanine plays a vital role in glucose-alanine cycle between tissue and liver. It is used for protein construction as well as involved in the metabolism of tryptophan and vitamin pyridoxine. It provides energy for muscles and central nervous system in order to strengthen the immune system. It helps in the metabolism of sugars and organic acids, and enhances the germination rates of Bacillus subtilis spores. It also displays a cholesterol-reducing effect in animals.정의
ChEBI: The L-enantiomer of alanine.제조 방법
Anthrobacter oxydans HAP-1 hyper produces DL-alanine in a nongrowth-associated manner.일반 설명
L-Alanine, a non-essential amino acid,?is produced enzymatically from?L-aspartate using aspartate β-decarboxylase.?It is the smallest among all the amino acids.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Safety Profile
Mutation data reported. When heated to decomposition it emits toxic fumes of NoxPurification Methods
Crystallise alanine from H2O or aqueous EtOH, i.e. crystallise it from 25% EtOH in water, or recrystallise it from 62.5% EtOH, wash it with EtOH and dry it to constant weight in vacuo over P2O5. [Gutter & Kegeles J Am Chem Soc 75 3893 1953, Walsh J Biol Chem 264 2394 1989.] 2,2'-Iminodipropionic acid is a likely impurity. [Beilstein 4 IV 2480. 2481.]L-알라닌 준비 용품 및 원자재
