StandardB.9A – Compare the structure and functions of
different types of biomolecules.
Essential Question How are lipids essential for life?

Lipids are molecules that are not soluble in water. They are nonpolar and hydrophobic.

The three categories of lipids include:• Fats
• Oils
• Waxes

Lipids can be used to:• Store energy.• Contain the most
energy per gram of any biomolecule. (9 Cal/gram)
• To form biological membranes and waterproof coverings. (waxy cuticle)

Many lipids are formed when a glycerol molecule combines with compounds called fatty acids.

Lipids contain only carbon (C), hydrogen (H), and oxygen (O).

Lipids
Structure: Functions:
Monomer: Polymer:
•Chain shaped•A backbone and 3 tails
Elements:•C, H, O
•Source for long term energy•Primary component of the cell membrane•waxy coating on the top of leaves (cuticle).
Good to know:•Saturated fats: contain single bonds•Unsaturated fats: contain double bonds
•Fatty acids •Triglyceride (lipid)

Energy in Food
• Burning carbohydrates – watch and write down your observations• Burning lipids – take notes and write down any observations• Calories in food – take notes…MAKE SURE you write down how many
calories per gram in each biomolecule AND the daily recommended allowance
