多糖是十个以上单糖脱水缩合而成大分子醣类。它和蛋白质、核酸、脂类构成生命四大物质。以前人们对多糖认识不足,认为多糖仅是营养物质。60年代后,人们才发现多糖具有各种功能,它能控制细胞分裂,调节细胞生长和衰老。它可作为免疫促进剂,对肿瘤、心血管疾患和肝炎具有治疗作用,从而引起人们的重视。国外科学家预言:“今后几十年将是多糖时代”。目前各国正深
Polysaccharides are more than 10 monosaccharide dehydration condensation macromolecule sugars. It and the protein, nucleic acid, lipids constitute the four life substances. In the past, people knew little about polysaccharides and thought that polysaccharides were only nutrients. After the 1960s, people discovered that polysaccharides have various functions.
