Introduction
Carbohydrates, lipids, proteins, and nucleic acids are organic molecules found in every living organism. These macromolecules are large carbon based structures. The macromolecules are assembled by joining several smaller units, called monomers, together through a chemical reaction called dehydration synthesis. The resulting polymer can be disassembled through the complementary process called hydrolysis.Carbohydrates are made of carbon, hydrogen and oxygen atoms in a 1:2:1 ratio. This means that for every carbon atom present in the carbohydrate there are two hydrogen atoms and one oxygen atom present. The monomers for carbohydrates are referred to as monosaccharides. When many monosaccharides are chained together the resulting molecule is called a polysaccharide. Carbohydrates are used by living organisms as an important source of energy. Examples of carbohydrates include glucose, fructose, sucrose, galactose, ribose, deoxyribose, cellulose and chitin.Lipids are also made of carbon, hydrogen and oxygen but the ratio of carbon, hydrogen, and oxygen is not 1:2:1. Instead, lipids have a much higher number of carbons and hydrogens with few oxygen atoms present. The nonpolar bonds that form between the carbon and hydrogen atoms of a lipid cause them to be hydrophobic, or water-repellent, molecules. This explains why water and oil do not mix. The large number of carbon to hydrogen bonds also serves to make lipids energy rich storage molecules. One gram of lipid stores
