Lactose on the other hand has a beta 1-4 glycosidic bond, meaning that carbon 1 of galactose and carbon 4 of glucose are bonded, but this time the molecules are stacked with one higher than the other.

乳糖中的糖苷键为β-1，4糖苷键，即半乳糖分子的1号碳与葡萄糖分子的4号碳以糖苷键相连，β代表了两个糖分子上下交叠，一高一低。

Insulin helps stimulate the liver to store glucose as glycogen in a process called glycogenesis - which is when some of the glucose molecules get linked together with alpha 1-4 and alpha 1-6 glycosidic bonds to form a polysaccharide called glycogen.

胰岛素还能促进肝细胞将葡萄糖转化为糖原，并贮存于肝脏，这个过程称为糖原生成，具体而言就是葡萄糖分子通过α-1，4糖苷键、α-1，6糖苷键结合成称为“糖原”的多糖的过程。
