Based on the source of origin, proteins are divided into two types, namely
animal proteins and vegetable proteins. Animal protein is a protein of animal
origin, for example fish, meat, eggs, and milk. Such food sources contain many
essential amino acids, so it includes 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 complete, so the
protein is not perfect. Soybeans are one of the foods of biological value among
animal proteins and vegetable proteins. Check Table 3.

Protein has a variety of functions in the

body, including produces energy; building
new cells and tissues; change damaged

such as enzymes, hormones, antibodies
and chromosomes; maintaining the

buffer pH.
