硫酸乙酰肝素是肝磷脂的前体，是重要的抗凝剂，目前只能从血液中提取，从未成功合成提取过，它并不是蛋白质，而是一种富硫似糖的分子，经常参与糖基化反应。
This is a precursor to heparin, an important anti-clotting agent that has, at present, to be extracted from blood, rather than being synthesised. Heparan sulphate is not a protein.
硫酸乙酰肝素并不是一种蛋白质，在某种程度上它只是经常参于糖基化的一种富硫的、类糖的分子。
Heparan sulphate is not a protein. It is, rather, a sulphur-rich sugar-like molecule of a sort often involved in glycosylation.
一旦进入血液中，糖分就会与蛋白质融合产生糖基化终产物(缩写为ages)。AGEs导致胶原蛋白挥发变硬产生皱纹。
Once in the bloodstream, sugar bonds with protein and creates advanced glycation end products (aptly abbreviated AGEs), which cause collagen to become inflamed and stiff, leading to wrinkles.
