矿物质在人体含量的多少,一般分为两大类,即占体重0.01％以上者,称为常量元素,如Ca、P、K、Na、C1、S、Mg等;占体重0.01％以下者,称为微量元素,如Fe、Zn、Mn、Co、Cu、Mo、I、Se、F等。常量元素在机体内的主要功能是:组成骨骼、软体组织和体内的许多复杂化合物;参与细胞的发育、增殖、分泌和氧化等;帮助食物的消化、吸收,以及体内废物的排泄;参与体内各种生理生化反应。人体对微量元 Mineral content in the human body, generally divided into two categories, accounting for more than 0.01% of body weight, known as the constant elements, such as Ca, P, K, Na, C1, S, Mg, etc .; , Called trace elements, such as Fe, Zn, Mn, Co, Cu, Mo, I, Se, F and so on. The major functions of the constant elements in the body are: to make up many complex compounds in bone, soft tissue and body; to participate in cell development, proliferation, secretion and oxidation; to help digestion and absorption of food and excretion of wastes in the body; Physiological and biochemical reactions.
