proteins

Proteins are large, complex molecules made up of smaller units called amino acids. They play vital roles in the body, including building and repairing tissues, supporting immune function, and facilitating biochemical reactions as enzymes. Proteins are essential for growth and development and are found in a variety of foods like meat, beans, nuts, and dairy products. The structure of a protein determines its function, and there are thousands of different proteins in the body, each with specific roles. Understanding proteins is key to nutrition, health, and biology.
