Diabetes:Insulin preparations according to the source of several

By source classification, insulin can be divided into cattle, pigs and human insulin three categories are:

⑴ bovine insulin: Since the cow came from the pancreas, the molecular structure of three amino acids in the human insulin and not the same, so稍差effect, prone to allergies or insulin resistance;

⑵ porcine insulin: Extract from the pig pancreas, in only one amino acid molecule with different human insulin, which means it with the people closest to the structure of insulin, the effect of higher antigen of the low, China's own production of insulin preparations main Insulin is a pig, including China's production of the highest purity of Xuzhou neutral insulin, or porcine insulin;

⑶ human insulin: obviously not from the extract of the pancreas. Human insulin from pigs into insulin from the porcine insulin and human insulin molecule in different amino acids into the same human insulin and amino acids, which turned into human insulin, or the use of recombinant technology synthetic. Clinical human insulin, antigen low, but prices more expensive. At present China is still不能自己production of human insulin, the market saw the human insulin comes mainly from Denmark, a small amount from the United States.
