According to the production mode of insulin, what types can it be divided into?

According to the production methods of insulin, it can be divided into two categories: animal insulin and human insulin. Animal insulin is extracted from the pancreas of pigs or cows through a special process, and after special processing, it is divided into pig insulin and bovine insulin. Their molecular structure is slightly different from that of insulin produced by human beings. Human insulin has the same structure as insulin produced by human body itself, and its purity is much higher than that of animal insulin. Human insulin is superior to animal insulin in terms of effect and side effects. However, because the price of animal insulin is much lower than that of human insulin, animal insulin is widely used.

According to the purity of animal insulin extraction, single-component insulin is the purest, unimodal insulin is the second, and ordinary insulin is the lowest.
