What are the four major categories of macromolecules? describe the basic structures and the primary functions of each.

The four macro molecules are nucleic acid, carbohydrate, proteins, and lipids.

Structure:  

1. Nucleic acids: Contain N in rings, nucleotides made of sugar, phosphate and nitrogenous base

1.Carbohydrates: Made of C,H, and O; –OH's on all carbons except one

2.Lipid: Made of C,H, and O; lots of C-H bonds; may have some C=C bonds (unsaturated)

3.Protein: Contain N, have N-C-C backbone

Function:

1.Nucleic acids: Stores and transfers info

2.Carbohydrates; Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall

3.Lipid: Insulator and stores fat and energy

4.Protein: Provide structural support, transport, enzymes, movement, defense.
