柠檬酸锌为白色粉末  ，稍溶于水  ，易溶于稀盐酸和碱性溶液中  ，分子量为610.37  ，几何构型为中心锌原子与两个柠檬酸的中间羟基及中间羧基和每一个柠檬酸的一个末端羧基相键合  ，构成锌的八面体结构 。美国的一些研究表明  ，停止人乳喂养的一岁婴儿的发锌值和血浆锌值低于成年人   ，而一直用人乳喂养的婴儿发锌值和血浆锌值维持成人水平 。前者造成锌值降低的因素可能是人乳中的锌比牛奶中的锌生物利用率高 。而且有研究者研究发现人乳喂养的婴儿比用奶粉即使是强化锌奶粉喂养的婴儿血浆锌值高  ，根据这些研究结果  ，可以推断人乳中存在一种婴儿易吸收的锌螯合物  ，它就是柠檬酸锌 。该结论已被人乳和牛奶的凝胶色谱所证实  ，在母乳中柠檬酸锌能改善锌的吸收 。柠檬酸锌也存在于人体前列腺中  ，对精液的活动具有一定影响  ，有研究发现在人体前列腺液和精液中  ，主要阴离子是柠檬酸  ，而氯离子浓度较低  ，说BB贝博艾弗森官方网站部分阳离子其中包括锌是与柠檬酸结合的 。在锌和男性不育的试验中  ，研究了精液能动中锌的生理作用  ，发现小分子螯合锌的浓度和精子活动之间有一定的相互关系 。

Physiological properties of Zinc Citrate

Zinc citrate is a white powder, slightly soluble in water, easily soluble in dilute hydrochloric acid and alkaline solution, the molecular weight is 610.37, the geometric configuration is the central zinc atom and two citric acid intermediate hydroxyl group and intermediate carboxyl group and a terminal carboxyl group of each citric acid phase bonding, forming the octahedral structure of zinc. Some studies in the United States have shown that one-year-old infants who stop human milk feeding have lower hair and plasma zinc values than adults, while infants who have been fed human milk maintain adult hair and plasma zinc values. The factor that caused the decrease of zinc value in the former may be that the zinc bioavailability in human milk is higher than that in milk. Moreover, some researchers have found that the plasma zinc value of infants fed with human milk is higher than that of infants fed with milk powder, even if it is fortified with zinc milk powder. According to these research results, it can be inferred that there is a zinc chelate that is easily absorbed by infants in human milk, which is zinc citrate. This conclusion has been confirmed by gel chromatography of human milk and milk, and zinc citrate in breast milk can improve zinc absorption. Zinc citrate also exists in the human prostate, has a certain impact on the activity of semen, some studies have found that in the human prostate fluid and semen, the main anion is citric acid, while the chloride ion concentration is low, indicating that most of the cations including zinc are combined with citric acid. In the experiment of zinc and male infertility, the physiological effect of zinc in semen motility was studied, and it was found that there was a certain correlation between the concentration of small molecule zinc chelate and sperm motility.
