L-(-)-트레오닌 C화학적 특성, 용도, 생산
화학적 성질
A white or almost white, crystalline powder or colourless crystals.용도
L-Threonine is used to alleviate anxiety and mild depression. It is an important component of many proteins such as tooth enamel, collagen, and elastin. It is an important amino acid in the nervous system and plays a vital role in porphyrin and fat metabolism. It is useful in intestinal disorders and indigestion. It is also used as a prodrug to reliably elevate brain glycine levels.정의
ChEBI: An optically active form of threonine having L-configuration.Safety Profile
Moderately toxic by intraperitoneal route. When heated to decomposition it emits toxic fumes of NOx.Purification Methods
Likely impurities are allo-threonine and glycine. Crystallise L-threonine from H2O by adding 4volumes of EtOH. Dry and store it in a desiccator. It also crystallises from 80% EtOH to give hexagonal plates m 262-263o(dec). It sublimes at 200-226o/0.3mm with 99.6% recovery and unracemised [Gross & Gradsky J Am Chem Soc 77 1678 1955].
