一般的微量元素无机盐及简单的有机盐在被动物摄入后  ，必须借助于辅酶的作用  ，与氨基酸或其他物质形成螯(络)合物后  ，才能被机体吸收  ，吸收后微量元素在血液中与某些蛋白质结合被运输到机体所需部位  ，才发生功效 。因此  ，微量元素氨基酸螯合物符合动物原始吸收模式  ，它既是机体吸收金属离子的主要形式  ，又是动物体内合成蛋白质过程中的中间物质  ，所以氨基酸微量元素螯合物不仅吸收快  ，而且可以节省许多生化过程  ，节约体能消耗  ，使其具有较高的生物学效价 。氨基酸螯合铁的相对生物效价测定采用公认的斜率比方法  ，以硫酸亚铁为参比标准物用四种铁营养敏感指标(血红蛋白、血清铁、血清铁蛋白和血清总铁结合力)  ，测得赖氨酸螯合铁和甘氨酸螯合铁的相对生物学效价分别介于102%~148%和103%~147%之间 。螯合铁在吸收、转运和利用方面都优于无机盐铁  ，与在铁元素和氨基酸等价的混合物相比较  ，螯合铁也显示出明显的营养优势 。体外酶学实验观测到甘氨酸螯合铁对血红素合成酶体系中σ-氨基γ-酮戊酸合成酶反馈抑制作用明显  ，有利于血红素的大量合成 。这是从机理阐明氨基酸铁补铁效果极佳的最好佐证 。

The biological value of Amino acid chelated iron

General trace element inorganic salt and simple organic salt after being ingested by animals, must rely on the action of coenzymes, and amino acids or other substances to form a chelate (complex) complex, in order to be absorbed by the body, after absorption of trace elements in the blood and some proteins are combined to transport to the body's required parts, before the effect occurs. Therefore, the trace element amino acid chelate conforms to the original absorption mode of animals, which is not only the main form of metal ions absorbed by the body, but also the intermediate substance in the process of protein synthesis in the animal body, so the amino acid trace element chelate is not only absorbed quickly, but also can save many biochemical processes, save energy consumption, so that it has a high biological titer. The relative biotiter of amino acid chelated iron was determined by the accepted slope ratio method, with ferrous sulfate as the reference standard and four iron nutrient sensitivity indexes (hemoglobin, serum iron, serum ferritin and serum total iron binding capacity). The relative biological titers of iron lysine chelate and iron glycine chelate were 102%-148% and 103%-147%, respectively. Chelated iron is superior to inorganic iron in terms of absorption, transport and utilization. Compared with the mixture of iron and amino acid equivalent, chelated iron also shows obvious nutritional advantages. In vitro enzymatic experiments have observed that iron glycine chelate has obvious feedback inhibition on σ-aminogamma-ketovalerate synthetase in heme synthetase system, which is conducive to the synthesis of large amounts of heme. This is the best evidence to illustrate the excellent effect of amino acid iron supplementation from the mechanism.
