自60年代人们发现锌缺乏症以来,人们对锌与人体健康的认识日益加深,发现锌是体内200多种金属酶的组成成分,它直接参与DNA、RNA和蛋白质的合成代谢,是构成机体组织、维持生理功能、促进生长发育的必需微量元素。锌与胎儿发育甚为密切,妊娠期妇女需要大量的锌来维持母体自身锌的代谢调节和胎儿发育的需要,此时锌供给不足,或其他因素,使锌吸收减少或排泄增多,都会导致母体缺锌,经胎盘传送给胎儿的锌减少,对胚胎或胎儿发育产生不良影响,表现为胎儿发育迟缓或发育不良,先天性锌缺乏症,严重时甚至导致胚胎畸形或死亡。
Since the discovery of zinc deficiency in the 60s, people’s understanding of zinc and human health has deepened. It is found that zinc is a component of more than 200 kinds of metalloenzymes in the body. It is directly involved in the synthesis and metabolism of DNA, RNA and protein and constitutes body tissues , Maintain physiological functions, and promote the growth and development of essential trace elements. Zinc and fetal development is very close, pregnant women need a lot of zinc to maintain the mother’s own metabolic regulation of zinc and the needs of fetal development, when the lack of zinc supply, or other factors, so that reduced zinc absorption or excretion increased, will lead to the mother Zinc deficiency, reduction of zinc delivered to the fetus through the placenta, has an adverse effect on embryo or fetal development, manifested as fetal retardation or dysplasia, congenital zinc deficiency, and even lead to embryo malformation or death in severe cases.
