the pancreas secretes insulin
Insulin is protein soluble and would be unable to cross the wall of the gastrointestinal tract without being broken down and the hormones in birth control pills are lipid soluble are correct.
You can't take insulin by mouth because the acids in your stomach would destroy it. http://www.healthline.com/sw/khs-using-injected-insulin
The answer is none. Just like Diabetics they have a level sugar and insulin. When sugar is so high they cannot balance out the insulin and become diabetics. The same meaning stands for Growth hormones and Anti Growth Hormones. They body produces growth hormones while at the same time Anti growth Hormones. There is no connection between the two.
An endocrinologist deals with hormones, like insufficient insulin. However, so do GPs and Internists.
The pancreatic beta islets produce insulin. Alfa cells produce glucagon. Insulin and glucogon produce a homeostatic method to produce normal blood glucose levels.
Insulin like many other peptide hormones is synthesized in the body as a pro-hormone that is then cleaved to become the more active hormone. Therefore the mature form could be said to the cleaved active horomone and not the 'juvenile' pro-hormone (actually used clinically as pro-insulin). However, in humans, the insulin of adults is the same as that of children.
hormones such as insulin opens up channel proteins which are like doors to a cell. Channel proteins allow larger molecules, such as sugar, to enter the cell.
Some hormones can get digested in the stomach, while others can't. Another example of one that has to be injected is insulin, although a powdered version that's inhaled is now available to bypass the stomach in a different way.
I think you mean 'Islets of Langerhan.' They are found in the pancreas. They are made up of endocrine cells, producing hormones like insulin and glucagon. The rest of the pancreas is exocrine tissue.
no, insulin has a strong smell though. my sister has diabetes.. but you wouldn't know what insulin tastes like. if you have tasted it, then your dead:P
Constantly and prodigeously Cell proteins are formed into at least three types of products which are i) structural eg. collagen; ii) functional such as enzymes and iii) regulatory hormones like insulin.
