People suffering from Diabetes have either the lack of insulin or decreased insulin activity. Insulin is a vital hormone and functions of insulin are essential for life. It is a polypeptide hormone produced by beta cells of islets of Langerhans in Pancreas. It plays an important role in energy metabolism and general growth and development of our body. Insulin acts in conjunction with Glucagon and other body hormones to maintain the blood glucose levels. Suboptimal glucose levels lead to either hypoglycemia or hyperglycemia both having profound implications on overall health and well being.
Diabetics use Insulin daily. So its important to know basics like - what exactly is Insulin? Here we will discuss about it and other Insulin basics like - How is it produced in our body? What are its sources and the differences between Human and Animal Insulin and get to know its structure. What is Insulin? Insulin is a polypeptide hormone secreted by Beta cells of Pancreas. Hormone is a vital substance produced in one part of the body transported through blood to act on the same or another part to alter (either increase or decrease) its functional activity. Peptide means a protein molecule made up of amino acids, the building blocks of proteins. Polypeptide indicates that it is made up of more than one peptides (see below).
