Detection of Biological Molecules

Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldn’t exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to […]
