How are proteins involved in structural tissues of the body?

For example, structural proteins maintain cell shape, akin to a skeleton, and they compose structural elements in connective tissues like cartilage and bone in vertebrates. Enzymes are another type of protein, and these molecules catalyze the biochemical reactions that occur in cells.

What are the physiological and structural roles of proteins?

Proteins are essential for the main physiological processes of life and perform functions in every system of the human body. A protein’s shape determines its function. Proteins are composed of amino acid subunits that form polypeptide chains. Hormones are a type of protein used for cell signaling and communication.

Which are examples of important proteins in the body?

Structural proteins provide support in our bodies, for example, the proteins in our connective tissues, such as collagen and elastin. Hormone proteins co-ordinate bodily functions, for example, insulin controls our blood sugar concentration by regulating the uptake of glucose into cells.
