成人体内大约有2.5g锌,分布于全身各组织器官,特别是视网膜、精子、前列腺及骨骼中浓度最高。科学家对锌与健康关系的研究已逾一百三十多年,但在很多领域还是知之不多。现在已知它至少参与体内100余种酶的活动,包括目前人们常提的超氧化物歧化酶(SOD)也含有锌的成分。这意味着体内有众多的生物化学反应需锌去催化完成。这是其它任何一种金属无素所不能比拟的。正因为这样,所以身体缺锌所表现的症状也比其它金属元素复杂得多。
About 2.5g of zinc in adults, distributed in the body tissues and organs, especially the retina, sperm, prostate and bone in the highest concentration. Scientists have been studying the relationship between zinc and health for more than a hundred and thirty years, but they still do not know much in many fields. It is now known to be involved in at least 100 enzymes in the body, including what is commonly known as superoxide dismutase (SOD), which also contains zinc. This means that the body has a large number of biochemical reactions need zinc to catalyze the completion. This is not any other kind of metal can not match. Because of this, so the symptoms of zinc deficiency in the body than other metal elements is much more complex.
