Ken R. WellsProtein
Protein are compounds composed of carbon,
hydrogen, oxygen, and nitrogen, which are arranged
as strands of amino acid. They play an essential role in
the cellular maintenance, growth, and functioning of
the human body. Serving as the basic structural mol-
ecule of all the tissues in the body, protein makes up
nearly 17% of the total body weight. To understandprotein’s role and function in the human body, it
is important to understand its basic structure and
composition.Amino Acids
Amino acids are the fundamental building blocks
of protein. Long chains of amino acids, calledpoly-
peptides, make up the multicomponent, large com-
plexes of protein. The arrangement of amino acids
along the chain determines the structure and chemical
properties of the protein. Amino acids consist of the
following elements: carbon, hydrogen, oxygen, nitro-
gen, and, sometimes, sulfur. The general structure of
amino acids consists of a carbon center and its four
substituents, which consists of an amino group (NH 2 ),
an organic acid (carboxyl) group (COOH), a hydrogenRecommended Dietary
