MACROMOLECULES OR BIOMOLECULES

4 Groups of Biomolecules: Carbohydrates l Proteins l Lipids l Nucleic Acids l

Carbohydrates Used for QUICK energy ex. glucose, starch. l Sugar + sugar = starch l

Proteins l l Made up of amino acids Used for building and repair, transport as part of the cell membrane, and enzymes.

l Enzymes are Proteins that are catalysts – they speed up the rate of chemical reactions. ● They end in -ase ex. amylase, transcriptase, etc. Su bs tra te ↓

Lipids l Used for STORING ENERGY l Examples: fats, oils, waxes l Part of cell membrane (phospholipid bilayer with polar heads and nonpolar tails)

l l DNA RNA

Nucleic Acids l l DNA contains the genetic code – It is a double helix Deoxyribose is the sugar Made up of nucleotides: 1. Sugar 2. Phosphate 3. Nitrogen Base

Nucleic Acids l RNA guides protein synthesis –it is a single strand - ribose is the sugar Made up of nucleotides: 1. Sugar 2. Phosphate 3. Nitrogen Base
