肌氨酸 Sarcosine 可以提高人的智力，尤其对于像学生考试这种需要“临时的场合”效果更明显。补充肌氨酸 可以增长肌肉无氧力量和爆发力。肌氨酸在肌肉中以磷酸肌酸的形式存在，人体在高强度运动时主要靠ATP 提供能量， 但人体内ATP 储备量很少，需要不断的合成，而磷酸肌酸可促进ATP 的合成。 Sarcosine is the N-methyl derivative of glycine. Sarcosine is metabolized to glycine by the enzyme sarcosine dehydrogenase, while glycine-N-methyl transferase generates sarcosine from glycine. Sarcosine is a natural amino acid found in muscles and other body tissues. In the laboratory, it may be synthesized from chloroacetic acid and methylamine. Sarcosine is found naturally as an intermediate in the metabolism of choline to glycine. Sarcosine is sweet to the taste and dissolves in water. It is used in manufacturing biodegradable surfactants and toothpastes as well as in other applications.
