BIOCHEMISTRY Part II

Macromolecule ReviewMacromolecule Review  Large carbon molecule chains are called Polymers  Made up of smaller units called monomers  Monomers  polymers ( macromolecules ) 1.Nucleic Acids: Contain C,H,O, N  Monomer = nucleotide  Nucleotides: made of 3 basic parts  Phosphate group  a sugar  nitrogen containing base

Proteins: Contain C, H, O, and N  Monomer= Amino acids  Same basic structure but differ at functional (R) group  20 amino acids  Forms peptide bonds  Polymer is called a polypeptide.

CARBOHYDRATES  Monomer = monosaccharide (simple sugar)  Made of C, H, and O and easily recognized by ring structure but no N like in DNA!!

CARBOHYDRATES MACROMOLECULES  2 monosaccharides = disaccharide  3 or more monosaccharides = polysaccharide such as starch or cellulose Disaccharide 

3. Carbohydrates3. Carbohydrates  Function: broken down to provide quick energy for cells  Example: sugars and starches (pastas, breads, candy etc)

4. Lipids4. Lipids  Monomer: Fatty Acids  Functions  Store Energy  Make up cell membranes  Used to make hormones

4. Lipids4. Lipids  Made up of C, H, O  Long and non polar  Hydrophobic: does not dissolve in water  Examples: fats, oils, phospholipids, steroids, waxes, and pigments  found in mayonnaise, ice cream, hot cheetos etc
