Bimply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specime book. It has survived not only five centuries.

BCH 201: Chemistry of Biomolecules

Chemistry of biomolecules deals with the nature, structure, function, and reactions of biomolecules like carbohydrates, proteins, lipid and nucleic acids. It also briefly discusses the role of vitamins and enzymes in medicine.
