The Role of Proteins in the Body

By August 23, 2008

Follow me on:

Proteins are very important molecules in our cells. They are involved in virtually all cell functions. Each protein within the body has a specific role. Some proteins are involved in structural support, while others are involved in bodily movement, or in defense against germs.

Proteins vary in structure as well as function. They are constructed from a set of 20 amino acids and have distinct three-dimensional shapes. Below is a list of a few types of proteins and their functions:

  • Antibodies defend the body from germs.
  • Contractile proteins are responsible for movement.
  • Enzymes speed up chemical reactions.
  • Storage proteins store amino acids.
