Macromolecules: Carbohydrate, Lipid, Nucleic Acid, Protein, Enzyme Carbohydrate: Sugars and starches which body breaks down to glucose • Structural function: cellulose and chitin • Energy storage: amylose, amylopectin, glycogen • Recognition molecules: glycoproteins and glycolipidsLipids: Fatty acids and their derivatives that are soluble in water • H and C and main components • Fats • Hydrophobic- thus help separate aqueous compartments • Store energy (fats, oils, adipose) Protein: Molecules composed of amino acids joined by peptide bonds • Monomer: amino acids (amino group + carboxylic acid)(20 types) • Keratin and Collagen (hydrophobic)- not soluble in water, found in structural protein • Globular proteins are hydrophilic (hemoglobin, antibodies, enzymes)
