Based on the source of origin, proteins are divided into two types: animal
and vegetable. Animal protein is a protein of animal origin, for example, fish,
meat, eggs, and milk. Such food sources contain many essential amino acids,
including perfect protein—meanwhile, vegetable protein, namely proteins
derived from plants, especially vegetables, grains, and legumes. The content of
food amino acids such as this is less than complete, so the protein is not perfect.
Soybeans are one of the foods of biological value among animal protein and
vegetable proteins. Check Table 3.
