肠道钙吸收机制解析与高效钙强化剂（天门冬氨酸钙Calcium L-Aspartate、甘氨酸钙Calcium Bisglycinate）的优化设计特征

人体主要吸收钙的部位位于肠道，人体中钙的吸收方式有两种：离子吸收和分子吸收。钙离子主要通过与维生素 D 结合成蛋白转运作用吸收，机体很容易运转离子钙，少量钙离子的通过细胞膜的渗透作用就可以被吸收。而分子钙不易被机体运转，其吸收主要以具有生物活性的分子型钙源进入体内，而余下的钙源分子，会被小肠粘膜吸收直接进入血液，胃酸分泌量不影响分子型钙源的吸收过程。因此，从以上结论和食物成分等角度考虑，良好的钙强化剂（天门冬氨酸钙Calcium L-Aspartate、甘氨酸钙Calcium Bisglycinate）有以下结构和特点：(1)左旋结构，即具有光学活性；(2)络合结构，络合常数适中；(3)水溶性好；(4)具有一定的脂溶性；(5)适中的分子量。

Analysis of the intestinal calcium absorption mechanism and the optimized design features of high-efficiency calcium enhancers (Calcium L-Aspartate, Calcium Bisglycinate)

The main site for calcium absorption in the human body is in the intestine. There are two ways of calcium absorption in the human body: ion absorption and molecular absorption. Calcium ions are mainly absorbed by combining with vitamin D to form protein transport. The body can easily transport ion calcium, and a small amount of calcium ions can be absorbed through the osmotic effect of the cell membrane. Molecular calcium is not easy to be transported by the body. Its absorption mainly enters the body as a biologically active molecular calcium source, and the remaining calcium source molecules will be absorbed by the small intestinal mucosa and directly enter the blood. The amount of gastric acid secretion does not affect the absorption process of the molecular calcium source. Therefore, considering the above conclusions and food ingredients, good calcium fortifiers (Calcium L-Aspartate, Calcium Bisglycinate) have the following structures and characteristics: (1) L-shaped structure, i.e. optically active; (2) complex structure, moderate complex constant; (3) good water solubility; (4) certain fat solubility; (5) moderate molecular weight.
