Starch is a homopolysaccharide of glucose. It is a storage polysaccharide of plants. Haemoglobin is the protein which transports gases like oxygen in higher animals like humans. mRNA is the template on which protein chain is synthesized in a cell. mRNA carries genetic information from nucleus to cytoplasm for translation into chain of amino acids. Sex hormones like androgens and estrogens are chemically steroids made up of cholesterol.
