INSULIN
Function
Insulin is located in the pancreas. It is made by the pancreatic islet cells. Insulin helps to regulate the blood glucose in the body. It converts the glucose into glycogen, storing it into the liver. The glycogen then converts the stored glycogen to glucose when the body is under fasting condition to provide energy. Insulin also helps to get rid of fatty acids. It slows the breakdown of triglycerides which leads to the reduction of fatty acids in the blood. When insulin is not able to produce from your body it causes your body to uses fatty acids for energy instead or carbohydrates.
Structure
Insulin is monomeric and is composed of two polypeptide chains. There are two different types of chains. Chain A haS 21 amino acids and Chain B has 30 amino acids. Insulin has a three dimensional structure consisting of 3 helices and 3 conserved disulfide bridges.
