An example of a protein is the type of nutrient found in meats.
These are all good sources of protein.
any of a large class of complex polymers consisting of long chains of polypeptides often bonded with nucleic acids, lipids, etc.: proteins are found in all cells, are essential to the diet of animals, are the basic components of cartilage, hair, skin, etc., and often function as enzymes, hormones, or antibodies
Origin of proteinGerman ; from French protéine ; from Classical Greek prōteios, prime, chief ; from prōtos, first (see proto-): from being a chief constituent of plant and animal bodies
Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids.

They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.
