Structure and Function of Proteins

Structure and Function of Proteins

Introduction: Proteins are an essential component of all living things. They make up muscles and hair, and at the molecular level, they are the molecules that produce the different traits an organism expresses.

Proteins are made from smaller components called amino acids. There are only 20 different amino acids that combine in an infinite number of different ways to produce all of an organism's possible traits.

Proteins are also special because they can exist in one of four different forms, each having a specific function. The diagram shows these four structures of proteins.
