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: -Amino acids are the monomers that make up proteins. Specifically, a protein is made up of one or more linear chains of amino acids, each of which is called a polypeptide.

Detailed explanation-3: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-4: -These molecules are called amino acids and our DNA can code for just 20 of them. Amino acids are organic molecules that contain both the amine ( ) and the carboxyl ( ) functional groups.
