This lab report is not perfect‚ but can serve as a guide in understanding how to write one! Introduction Insulin‚ an amino-acid based protein‚ helps make up a larger polypeptide chain‚ proinsulin‚ which is located within the beta cells of the pancreas. Enzymes release the insulin from the larger proinsulin chain just before it is secreted from the beta cells. Insulin’s main function is to lower blood glucose levels by speeding up the membrane transport of glucose from the blood and into
