多肽是指由氨基酸组成,氨基酸用肽健连接而成的一类化合物,其在连接方式上与蛋白质相同,通常将少于100个氨基酸组成的称为多肽,而由100个以上氨基酸组成的为蛋白质。但在某些性质方面多肽又有别于蛋白质,如其空间结构较简单、稳定性较高、免疫原性较低或无免疫原性等。 Polypeptides refer to a class of compounds consisting of amino acids that are linked by peptide bonds and are the same as the protein in the ligation pattern and are usually referred to as polypeptides with less than 100 amino acids and polypeptides consisting of more than 100 amino acids protein. However, in some aspects of the nature of the polypeptide is different from the protein, such as its spatial structure is relatively simple, high stability, low immunogenicity or non-immunogenicity.
