Macromolecule 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. Carbohydrates

Function: broken down to provide quick energy for cells

Example: sugars and starches (pastas, breads, candy etc)

4. Lipids

Monomer: Fatty Acids

Functions Store Energy Make up cell membranes Used to make hormones

4. 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
