Describe the process of making the four major macromolecules.

Explanation:

Structure:

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

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

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

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

Function:

Nucleic acids: Stores and transfers info

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

Lipid: Insulator and stores fat and energy

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