Molecular Structure

What is a polymer? Monomer?

How are they assembled?

Page 7: Molecules of Life. Carbon Compounds The Versatile Carbon Atom Carbon has 4 electrons in outer shell Can form a bond with four other molecules.

Monosaccharaides are single-unit sugars

These molecules typically have a formula that is a multiple of CH2O

Each molecule contains hydroxyl groups and a carbonyl group

Monosaccharaides are the fuels for cellular work

Carbohydrates

Isomers

Glucose and fructose are isomers They contain the

same atoms but in different arrangements
