生化/生理作用
缬氨酸是必需氨基酸，参与谷氨酰胺和丙氨酸的生物合成。缬氨酸是支链氨基酸（BCAA），维持着BCAA之间的平衡。L-缬氨酸是一种能量燃料。长期缺乏 L-缬氨酸会导致生长不足、器官损伤和肌肉质量损失。

Short-chain acylations of lysine residues in eukaryotic proteins are recognized as essential posttranslational chemical modifications (PTMs) that regulate cellular processes from transcription, cell cycle, metabolism, to signal transduction. Lysine butyrylation was initially discovered as a normal straight chain butyrylation (Knbu).
