Protein is a naturally occurring, complex substance made up of amino acid residues joined by peptide bonds. These molecules are essential for the proper functioning of the body.
Here are some key roles of proteins:
- Structural components: They form the basis of body structures such as skin, hair, and muscles.
- Enzymes: They catalyze biochemical reactions within the body.
- Cytokines: They act as signaling molecules for cell communication.
- Antibodies: They help the immune system fight off infections.
Proteins are found in various foods, including meat, cheese, fish, eggs, beans, nuts, seeds, and soy products.
