中文百科
亮氨酸
亮氨酸是二十种基本氨基酸的其中一种，它和异亮氨酸互为同分异构体。在营养学上，亮氨酸是人体的必需氨基酸。
亮氨酸是在蛋白质内最常出现的氨基酸，而且对于婴儿与孩童时期的正常发育和成年人身体内的氮平衡都很重要。据推测，亮氨酸可能在以平衡蛋白质的生化和分解的方法来维持肌肉上占了很重要的角色。
亮氨酸的主要食物来源有：全谷、牛奶、乳制品、蛋、猪肉、牛肉、鸡肉、豆类、叶菜。

Leucine 亮氨酸
![Human metabolic pathway for β-hydroxy β-methylbutyric acid (HMB) and isovaleryl-CoA, relative to leucine.[4] Like leucine, HMB also activates mTOR signaling, in addition to other anabolic and anti-catabolic signaling mechanisms (e.g., proteasome inhibition) in skeletal muscle tissue.[4][5] Of the two major pathways, leucine is mostly metabolized into isovaleryl-CoA, while only 5% or so is metabolized into HMB.[4]](/uploads/202501/24/ISSN_HMB_statement_Fig_14627.jpg)
Leucine (abbreviated as Leu or L; encoded by the six codons UUA, UUG, CUU, CUC, CUA, and CUG) is an α-amino acid used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH+
3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO form under biological conditions), and an isobutyl side chain, classifying it as a nonpolar (at physiological pH) amino acid. It is essential in humans—meaning the body cannot synthesize it and thus must obtain from the diet.
