营养学中的EAA,全称为Essential Amino Acids,由9种必需氨基酸组成。这些氨基酸是赖氨酸、苏氨酸、色氨酸、亮氨酸、异亮氨酸、缬氨酸、组氨酸、苯丙氨酸和蛋氨酸。它们在人体内无法自行合成,必须通过食物摄入。为了增强营养价值,有时还会加入卵磷脂等成分。这些氨基酸在营养学中扮演着至关重要的角色,是维持人体正常生理功能不...
the nine essential amino acids are obtainable by a single complete protein. A complete protein, by definition, contains all the essential amino acids. Complete proteins usually derive from
