Is it true that insulin is derived from pigs.?

Question

I will definately need some type of documentation to follow up with on your answer. This has to be a resource that I can acquire.

Answer 1

Some insulin is derived from pigs and some from beef. However, in the United States most insulins are analog, or human recombinant made with the use of bacteria or yeast to duplicate the altered protein.

Where Does Commercial Insulin Come From?

The first successful insulin preparations came from cows (and later pigs). The pancreatic islets and the insulin protein contained within them were isolated from animals slaughtered for food in a similar but more complex fashion than was used by our doctor and med-student duo. The bovine (cow) and porcine (pig) insulin were purified, bottled, and sold. Bovine and porcine insulin worked very well (and still do!) for the vast majority of patients, but some could develop an allergy or other types of reactions to the foreign protein (a foreign protein is a protein which is not native to humans). In the 1980's technology had advanced to the point where we could make human insulin. The advantage would be that human insulin would have a much lower chance of inducing a reaction because it is not a foreign protein (all humans have the exact same insulin, so we do not "see" this as a foreign protein). The technology which made this approach possible was the development of recombinant DNA techniques. In simple terms, the human gene which codes for the insulin protein was cloned (copied) and then put inside of bacteria. A number of tricks were performed on this gene to make the bacteria want to use it to constantly make insulin. Big vats of bacteria now make tons of human insulin. From this, pharmaceutical companies can isolate pure human insulin.

Answer 5

Sounds like you need homework help. Why not just yahoo or google it. The lik below states "The insulin products used by people with diabetes are either taken from animals (pigs or cows) or manufactured in labs to be identical to human insulin. Beef insulin is no longer available in the United States. Beginning in January 2006, pork insulin for human use will no longer be manufactured or marketed in the U.S."

Answer 6

Forget anything you have ever been told about Diabetes.

And get this - it has nothing to do with insulin, exercise, diet or anything else you've heard in the past. It's all based on latest breakthrough research that Big Pharma is going Stir Crazy to hide from you.

Answer 7

The first insulin extracted for humans came from dogs (Banting and Best).

Pigs and cows were next for human extraction. I believe sheep too. Recombinant human DNA is the norm now, however, pigs and cow insulin is still available to some people who are resistent to recombinant DNA. Also, its available for diabetic pigs and cows.

Answer 8

It used to be. From pigs, and cows. Today, mostly human recombinant (genetically manufactured) insulin is used.

Answer 9

I always heard it was from sheep.

Answer 10

they don't make it that way anymore.
