Detailed explanation-1: -A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides. Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next.

Detailed explanation-2: -Proteins are polypeptide structures consisting of one or more long chains of amino acid residues. They carry out a wide variety of organism functions, including DNA replication, transporting molecules, catalyzing metabolic reactions, and providing structural support to cells.

Detailed explanation-3: -Proteins are composed of long chains of amino acids.

Detailed explanation-4: -The common property of all proteins is that they consist of long chains of -amino (alpha amino) acids. The general structure of -amino acids is shown in . The -amino acids are so called because the -carbon atom in the molecule carries an amino group (―NH2); the -carbon atom also carries a carboxyl group (―COOH).
