we discussed procollagen. Explain what this means in the context of cell biology. Can you find another example of a protein in the proform?
Answer- Procollagen is a precursor or proform of collagen. It is the protein that provides strength and support to the body tissues. Another example of protein in proform is Proinsulin.
Proinsulin is a proform of insulin synthesized in the beta cells of the islets of Langerhans of pancreas. It consists of A chain, B chain, and the area connecting the two, the C peptide. Disulfide bonds are present between the A and B chains. It requires three disulfide bonds to form a mature insulin in which two of these disulfide bonds are between the A and B chains.
