印度人 Khanna P.等从苦瓜(Momordica charantia)的组织、果实和种子中分离得到一具有类似胰岛素的降糖活性的多肽,称之为“植物胰岛素”。经研究表明,其分子量大约为11000,是包括17种166个氨基酸残基所组成的多肽,在其组成的氨基酸中只有甲硫氨酸是在牛胰岛素中所不存在的。免疫学测定表明,“植物 Indian Khanna P. from Momordica charantia organizations, fruits and seeds isolated from a similar insulin hypoglycemic activity of the polypeptide, called “plant insulin.” Studies have shown that the molecular weight of about 11000, is composed of 17 kinds of 166 amino acid residues in the composition of the amino acids in the only methionine is not found in bovine insulin. Immunological assays show that "plants
