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:
carbohydrateslipids
energy
