Definition: What are amino acids?

There are 20 different amino acids that can be found in proteins, each with its own unique structure and function. These amino acids are linked together in a specific sequence to form polypeptide chains, which then fold into complex three-dimensional structures to create functional proteins.

Amino acids are classified into two main categories: essential and non-essential. Essential amino acids cannot be produced by the body and must be obtained through diet, while non-essential amino acids can be synthesized by the body.

Each amino acid has its own specific role in the body. For example, some amino acids act as precursors for the synthesis of neurotransmitters like serotonin and dopamine, which play a crucial role in regulating mood and emotions. Others are involved in the production of collagen, a protein that provides structural support to tissues such as skin, bones, and tendons.
