微量元素锌与一系列的代谢有关,人体中锌的缺乏将会导致一系列代谢紊乱和病理变化,致使DNA、RNA的合成减少,结缔组织蛋白、肠粘液蛋白的合成及维生素A的代谢过程受到干扰。又、锌参与了,核酸和蛋白质的代谢过程,在纤维细胞增殖和胶合过程中起关键作用,因而缺锌就会出现一系列与生长发育迟缓、性机能障碍等有关的症状。锌参与缺血缺氧肌肉中能量代谢,锌可改善血流灌注,因而与肢体动脉硬化性跛行有关。锌在眼含色素的组织中浓度很高,当维生素A醇转变成能制造视紫质的 Trace element zinc is related to a series of metabolism. The lack of zinc in the human body will lead to a series of metabolic disorders and pathological changes, resulting in the reduction of synthesis of DNA and RNA, the synthesis of connective tissue protein, intestinal mucus protein and the metabolism of vitamin A interference. Also, zinc participates in the metabolic processes of nucleic acids and proteins and plays a key role in fibroblast proliferation and gluing processes, and thus zinc deficiency presents a series of symptoms associated with growth retardation, sexual dysfunction, and the like. Zinc participates in energy metabolism in hypoxic-ischemic muscle, and zinc improves blood perfusion, and thus is associated with arteriosclerotic limping. Zinc is highly concentrated in the eye’s pigmented tissue and when vitamin A is converted to rhodopsin
