Extended information;

The ingested protein is digested and hydrolyzed into amino acids in the body and absorbed, then the protein needed by the human body is synthesized. At the same time, new proteins are constantly metabolized and decomposed. Always in dynamic equilibrium.

Proteins are divided into complete proteins and incomplete proteins. Rich in essential amino acids, high-quality proteins are collectively called complete proteins, such as milk, eggs, fish, meat, etc., and soybeans in plants also contain complete proteins. Proteins that lack essential amino acids or have very low content are called incomplete proteins, such as proteins contained in cereals, wheat, and corn, and gelatin in animal skins and bones.
