氨基酸组成蛋白质。二十种氨基酸里，你的身体可以合成十一种：
# Alanine (from pyruvic acid)
# Arginine (from glutamic acid)
# Asparagine (from aspartic acid)
# Aspartic Acid (from oxaloacetic acid)
# Cysteine
# Glutamic Acid (from oxoglutaric acid)
# Glutamine (from glutamic acid)
# Glycine (from serine and threonine)
# Proline (from glutamic acid)
# Serine (from glucose)
# Tyrosine (from phenylalanine)
另外九种，必须由食物获得。没有的话，梨叔很生气，后果很严重：））
# Arginine
# Isoleucine
# Histidine
# Leucine
# Methionine
# Lysine
# Phenylalanine
# Tryptophan
# Threonine
# Valine
别以为只有肉蛋奶才有蛋白质。蔬菜和米面都含有蛋白质。麦老弟一直在实践？不摄入蛋白质？还活着？一定是外星人吧：））
