WebCollagen. Collagen is the most abundant protein in the body. Its fiber-like structure is used to make connective tissue. Like the name implies, this type of tissue connects other tissues and is a major component of bone, skin, muscles, tendons, and cartilage. It helps to make tissues strong and resilient, able to withstand stretching. WebThe other parameter which can be controlled to accelerate the wound healing process is the rate of synthesis of collagen. 73 The first step in synthesis of collagen is hydroxylation of proline to form hydroxyproline. 91 Thus, the hydroxyproline content is a good marker for collagen deposition, which has been determined in several studies on the application of …
