Question

Polypetides having molecular weights above 10000 are known as:

• A. amino acids
• B. hormones
• C. proteins
• D. terminal amino acids

Answer 1

The correct option is C proteins

Peptides containing more than 10 amino acids are called poly peptides. Poly peptides are formed by the linear sequence of amino acids. Some proteins are composed of two or more poly peptide chains. Relatively shorter peptides are known as oligopeptides whereas longer polymers are called polypeptides. Polypeptides containing more than 100 amino acids having molecular mass higher than 10,000 are generally called as proteins. However the distinctive between a polypeptide and a protein is not sharp.
