1 支链氨基酸代谢支链氨基酸(branched-chain amino acids,BCAA)包括亮氨酸(Leu)异亮氨酸(He)和缬氨酸(Val),它们都是必需氨基酸。由于支链氨基酸分解代谢的关键酶转氨酸在肝内的活性过弱,其代谢主要在骨骼肌中进行。小部分BCAA
1 Branched-chain amino acids (BCAA) include Leu, Iso and Leu, all of which are essential amino acids. Since the key enzyme of branched-chain amino acid catabolism, the activity of lysine in the liver is too weak, its metabolism is mainly carried out in skeletal muscle. A small part of BCAA
