Cysteine-rich intestinal protein (CRIP) is a newly identified peptide that occurs primarily in the intestine and binds zinc in the mucosa during absorption. High dietary zinc does not affect CRIP concentration, but it greatly increases metallothionein, which may compete with CRIP to decrease zinc absorption.
富含半胱氨酸的肠蛋白(CRIP)是一种新发现的肽,主要存在于肠道中,在吸收过程中与黏膜中的锌结合。高锌饮食不影响CRIP的浓度,但会大幅增加金属硫蛋白,而金属硫蛋白可能会与CRIP竞争,从而降低锌的吸收。
