BIOL-L 101 - Biological Molecules

BIOLOGICAL MOLECULES

All life on earth shares a common chemistry indirect evidence for evolution All cells contain only a few groups of carbon-based compounds The molecules →Carbohydrates - used as respiritory substrates, form Structural components in plasma membranes and cell walls Lipids used to form bilayer of plasma membranes, certain hormones, act as respiritory →Proteins- form many cell structures, enzymes, chemical messengers, components oc the blood Substrates → Nucleic acids Carry genetic code for production of proteins viruses →Water most Common + all living organisms - evidence for component of ceus Common to evolution monomers and polymers → monomers made are the Smaller units from from which larger molecules are Polymers are made from a large number of monomers joined joined together
