Document Summary
There are differences in the 3 basic components that are responsible for the variation in appearance and form, qualities, and function among the 5 major types of tissue: metabolism and structure, providing a protective sheath around organs. Insulating the body: serving as an energy reserve, providing a structural framework for the body, serving as a medium for transporting substances across the body, healing and defense of the body. Collagen is the most abundant protein in the body; it makes up 20% to 25% of total body protein. The high tensile strength of collagen makes it an important structural component of tendons and ligaments which are constantly being pulled and stretched. Collagen has very important structural roles in muscle. Collagen is responsible for the background toughness of beef. Collagen fibres are made up of collagen fibrils that are composed of tropocollagen molecules that are synthesized by fibroblasts. Collagen content of muscle has an impact on meat tenderness both quantitatively and qualitatively.
