HAPPY MONDAY Bellwork:

-On your Bellwork Sheet write “Study for Quiz”

-Quiz will be over Levels of Organization and Basic

Chemistry.

REMINDERS

• Projects Due tomorrow• Notecards Due Wednesday• Quiz Friday• Test next Monday

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.

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

fatty acids.

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

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

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)

Carbohydrate

Structure: Functions:

Monomer: Polymer:

•Circle or ring shaped•Create a 1:2:1 ratio

Elements:•C, H, O

•Main source of immediate energy

Good to know:•Often known as simple (monomers) and complex (polymers)

•Monosaccharide•Examples: glucose, sucrose

•Polysaccharide•Examples: starch, cellulose

As always, summarize what you have learned about carbohydrates

and lipids in 30 words. In your summary, you must use the words:

energy
