Four macromolecules: Macro (LARGE) They are all independent of each other

·      PROTEINS

·      LIPIDS

·      CARBOHYDRATES

·      NUCLEIC ACIDS

PROTEINS:

·      Composed of amino acids

·      They are polymers (MANY AMINO ACIDS)

o   AMINO ACIDS: 3 Groups

§  Carbon (4 bonds)

§  Nitrogen (3 bonds)

§  Oxygen (2 bonds

§  Hydrogen (1)

§  Sometimes Sulfur (2)

AMINO ACIDS HAVE THREE GROUPS

·      Amino Group (H²N)

·      Carboxyl Group (COOH)

·      Central Carbon Atom (CHR²)
