N-乙酰肌碱(NAC)具有抗衰老、抗氧化和抗糖基化的作用
N-Acetyl carnosine (NAC) is a naturally occurring compound chemically related to the dipeptide carnosine. The NAC molecular structure is identical to carnosine with the exception that it carries an additional acetyl group. The acetylation makes NAC more resistant to degradation by carnosinase, an enzyme that breaks down carnosine to its constituent amino acids, beta-alanine and histidine.
N-乙酰肌碱(NAC)是一种天然的化合物，在化学上与二肽肌碱有关。NAC的分子结构与肌碱相同，除了它携带一个额外的乙酰基。乙酰化使NAC更能抵抗肌氨酸酶的降解，肌氨酸酶是一种将肌氨酸分解为其组成氨基酸、-丙氨酸和组氨酸的酶。
