MACROMOLECULES OR BIOMOLECULES

4 Groups of Biomolecules: Carbohydrates Proteins Lipids Nucleic Acids

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

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

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

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

DNA RNA

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