  • Mechanisms of protein degradation in mantle muscle

    2012-8-15 · cephalopods typically feed upon protein-rich diets and are generally high in protein content with low reserves of lipid and carbohydrates. Most of the lipid is present in the digestive gland with very low lipid reserves in other tissues ().Studies tracking the incorporation of radiolabeled phenylalanine into the protein pool show that in feeding cephalopods, protein accretion is favored by ...
