A peptide is a chain of amino acids linked to one another by amide (peptide) bonds. A peptide bond is the covalent chemical bond formed when the carboxyl group of one amino acid reacts with the amino group of another. The word peptide is derived from the greek word πεσσειν, which means “to digest.” Peptides are an essential part of nature and there are thousands of them that occur naturally in the human body and in animals, but new synthetic peptides are being discovered daily, which show a promising future for health and drug development. The benefits of peptides on health have been demonstrated in numerous research studies related to neurological function, anti-aging, muscle growth, skin wrinkles, growth hormone deficiency and so forth.
