Biomolecules Molecular basis of life

Polymers “mer” means unit “mono” means one Monomer-one unit “poly” means many Polymer-many units Polymers are made of many monomers

Biomolecules Four majors types of Biomolecules Carbohydrates Lipids Proteins Nucleic Acids

Carbohydrates Monomer-simple sugar like glucose Stores energy and provides structure Simple Sugars Glycogen Starch – in plants Blank

Candy Question What are lipids?

Lipids Used to store energy One gram of fat contains over twice the energy of one gram of carbohydrate Important categories Fats, Oils, Waxes Steroids Phospholipids Structure Glycerol molecule + 3 fatty acids

Proteins Monomer-amino acid Provide structure and help chemical reactions Enzymes-speed up chemical reactions

Candy Question What is the last type of biomolecule? What is a common name for this type of biomolecule?

Monomer-Nucleotide Stores and transmits genetic information Two types Deoxyribonucleic acid – DNA Ribonucleic acid - RNA Nucleic Acids

Candy Question What is the relationship between a monomer and a polymer?

Candy Question Without looking, name the four types of biomolecules.

Candy Question What do enzymes do?
