Collagen is a structural protein necessary for the maintenance of healthy blood vessels, muscle, skin, bone, and cartilage in animals; it is also the most common protein in the animal kingdom. The production of collagen in animals is achieved through a metabolic pathway that includes two enzymes that must be bound to vitamin C in order to catalyze their reactions; the names of these enzymes are prolyl hydroxylase and lysyl hydroxylase. Though many animal species are able to synthesize their own vitamin C from glucose, primates are among a handful of animals who have lost this ability through the course of evolution and thus must attain vitamin C through their diets. In humans, one of the effects of a diet lacking in vitamin C is scurvy, a disease that includes symptoms like poor wound healing, loosening of teeth, small red spots on the skin, and easy bruising.
