==Background==
*Nutritional deficiency of Vitamin C (Ascorbic acid)
*Vitamin C is typically foundin fruits and vegetables.
*Vitamin C is a cofactor for hydroxylation of proline and lysine amino acids in procollagen molecules, which is required for cross-linking collagen's triple helix.  
*Scurvy therefore leads to unstable collagen and collagen fragility.
**leaking of vascular structures
***gingival bleeding
***petechiae
***easy bruising
*Vitamin C is also required for the disulfide bonding in hair leading to corkscrew appearance of hair.
