铬是动物机体必需微量元素之一,在人体中代谢中也起着重要的作用,它可以作为葡萄糖耐受因子的组成成分,协助胰岛素发挥生理功能。它可促进胰岛素的生物学功能,同时控制着氛基酸、糖和脂代谢全过程,缺铬能影响糖耐量和引起血脂代谢紊乱,引起疾病。运动可导致机体对铬需求的增加,铬补充对运动员肌肉力量、瘦体重可产生较好影响。本文主要综述了铬在人体内的存在与代谢,生物学作用,以及其与糖代谢的关系。
Chromium is one of the essential trace elements in animal body and plays an important role in the metabolism of human body. It can act as a component of glucose tolerance factor and help insulin exert its physiological functions. It can promote the biological function of insulin, while controlling the whole process of acid, sugar and lipid metabolism, lack of chromium can affect glucose tolerance and cause dyslipidemia, causing disease. Exercise can lead to the body’s increased demand for chromium, chromium supplementation on the athlete’s muscle strength, lean body mass can have a better impact. This article reviews the existence and metabolism of chromium in the human body, biological role, and its relationship with glucose metabolism.
