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 BiomoleculesCarbohydrates

Lipids

Proteins

Nucleic Acids

Carbohydrates

Monomer-simple sugar like glucose

Stores energy and provides structure

Simple Sugars

Glycogen

Starch – in plants

Candy Question

What are lipids?

LipidsUsed to store energy

One gram of fat contains over twice the energy of one gram of carbohydrate

Important categoriesFats, Oils, Waxes

Steroids

Phospholipids

StructureGlycerol molecule + 3 fatty acids

Proteins

Monomer-amino acid

Provide structure and help chemical reactions

Enzymes-speed up chemical reactions
