Summary Introduction
To review:
The effect of deficiency of Vitamin C (scurvy) on bone tissue, dense regular collagenous connective tissue, dense irregular connective tissue, and cartilage. Collagen requires Vitamin C for its synthesis. The symptoms expected from scurvy.
Introduction:
Collagen is one of the types of protein fibers. It is a major protein in the human body. It is made up of fibrous protein, and is resistant to tension and pressure. This protein is responsible for smoothness of skin. It is found in bones, tendons, cartilage, and in extracellular tissue.

Collagenopathies, conditions characterized by the production of one or more types of defective collagen proteins, are in a group of disorders called connective tissue diseases. Many collagenopathies feature arthritis or other joint problems as part of the symptoms of the disorder. Why would defective collagen proteins affect an individual's joints?
the disease scurvy caused by a deficiency in vitamin C leads to an inability to synthesize the protein collagen. Would prescribing calcium salts help to treat the primary bone problem in the disease Why or why not
