Proteins
Proteins are abundant in living systems. They are involved in almost all aspects of a cell's ability to
maintain homeostasis. Different types of proteins include enzymes, transport proteins, hormones,
structural proteins, defense proteins, storage proteins, and contractile proteins. Due to the differences in
their structure, proteins perform various functions including carrying substances throughout the body,
constructing new structures, aiding in digestion, and coordinating the activities of the body. All cells build
diverse proteins using the same building blocks of amino acids. There are 20 different amino acids that
can be combined to make a protein. Structural similarities within amino acids allow for protein synthesis
to be a regulated process, while differences within amino acids allow for interactions that create unique
protein structures. An amino acid attaches to another amino acid by a peptide bond, forming a peptide.
Polypeptides are formed when many amino acids link together to form a chain. Proteins are created as
amino acids in one or more polypeptide chemically interact, fold, and create their three-dimensional
structure. The diagram shows the formation of a protein.
