人血清白蛋白(Human Serum Albumin,简称HSA)是人血浆中主要的蛋白质,其非糖基化的单链多肽包含585个氨基酸,分子量为66kD。在血浆中其浓度为42g/L,约占血浆总蛋白的60％。在体液中人血清白蛋白可以运输脂肪酸、胆色素、氨基酸、类固醇激素、金属离子和许多治疗分子 Human Serum Albumin (HSA) is the major protein in human plasma. The non-glycosylated single-chain polypeptide contains 585 amino acids and has a molecular weight of 66 kD. Its plasma concentration of 42g / L, accounting for about 60% of total plasma protein. Human serum albumin can transport fatty acids, bile pigments, amino acids, steroids, metal ions and many therapeutic molecules in body fluids
