Introduction to proteins
Proteins are polypeptides made up of amino acids joined together by polypeptide bonds. The number of amino acids in a protein molecule can vary from several amino acids to thousands of amino acids. Proteins are made of a combination of several of the 20 naturally occurring amino acids as well as other minor amino acids. Proteins are very important molecules in the body .They form the structural components of animal and human tissue (Yildiz, 2009).
The primary structure of proteins is determined by the sequence of the amino acids in the protein. A functional amino acid must contain the correct sequence ...
