乳糖与其他糖和多元醇一样，在碳酸氢盐缓冲液存在下防止或延迟钙离子沉淀。通过使用纸电泳和钙-45作为复合物的标记，证明形成不带电荷的钙-乳糖复合物。糖对钙离子的肠道吸收的促进作用可能是由一种低分子量的复合物引起的。
Lactose, like other sugars and polyols, prevents or delays the precipitation of calcium ion in the presence of bicarbonate buffer. That an uncharged calcium-lactose complex is formed was demonstrated by the use of paper electrophoresis and of calcium-45 as a label for the complex. Enhancement of the intestinal absorption of calcium ion by sugars could result from a complex of low molecular weight.
