protein

Amino acid chain

Protein is one of the three main nutrients in food, along with carbohydrates and fat.

Proteins are large molecules made of amino acids, essential for building and repairing tissue.

Eggs are a good source of protein.

In nutrition talk, protein often means high-protein foods generally: I need to eat more protein.

Athletes and dieters track their protein intake closely.
