1) Enzymes: Proteins act as biological catalysts, known as enzymes, which function to speed up chemical reactions in the body. These enzymes are involved in various metabolic processes such as digestion, energy production, and DNA replication. They help in breaking down complex molecules into simpler ones or building complex molecules from simpler ones.
2) Structural support: Proteins also play a crucial role in providing structural support to cells and tissues. The protein collagen, for example, forms the main component of connective tissues such as skin, bones, and tendons, providing strength and elasticity. Similarly, proteins like actin and myosin are responsible for the contraction and movement of muscles. Proteins also form part of the cytoskeleton, a network of fibers that helps maintain cell shape and provides mechanical support.
