Due to their weight, macromolecules make up a great part of a living organic cell. Biological molecules are put under groups based on the way they behave and the similarities they share. There are four main types of macromolecules, namely proteins, nucleic acids, fats and membrane lipids and carbohydrates (which include monosaccharides and polysaccharides). (Alberts, Walter, Bray, Hopkin, Johnson, & Lewis, 2015) There are four smaller organic molecule families which are the primary components of macromolecules. These four molecules are the sugars, nucleotides, amino acids and fatty acids. The sugars link together to form carbohydrate molecules, fatty acids link together to form lipids and fats, amino acids form together to form proteins and
