D-亮氨酸 MSDSD-2-Amino-4-methylpentanoic acid
亮氨酸是一种可以在很多蛋白质里发现的氨基酸,被认为是吸收多种不同营养素所必需的;可用于生化研究;亮氨酸可作为营养补充剂,很受运动员青睐;此外,亮氨酸还可作为食物添加剂,增强食品口味。
亮氨酸、异亮氨酸和缬氨酸都是支链氨基酸,它们有助于训练后肌肉的恢复,控制血糖,并给身体组织提供能量。其中,D-亮氨酸是最有效的一种支链氨基酸,但是人体自己不能生产,只能通过饮食获得,但普通食品中几乎不含D-亮氨酸,D-亮氨酸多出现在细菌的肽聚糖中。
Human Endogenous Metabolite
In a screen of candidate neuronal receptors, D-leucine failed to compete for binding by cognate ligands, potentially suggesting a novel target. Even at low doses, D-leucine suppressed ongoing seizures at least as effectively as diazepam but without sedative effects. These studies raise the possibility that D-leucine may represent a new class of anti-seizure agents, and that D-leucine may have a previously unknown function in eukaryotes.
