Protein are one of the building blocks of life. They are complex molecules built up from amino acid residues. Both animals and plants use proteins, and these can be ingested by humans and used for their own needs. As an energy source, or food, proteins provide the same amount of energy as carbohydrates.
Bacteria also use proteins and can serve as a food source.
