Name at least two reasons why lipids are important.

What is the difference between a saturated and unsaturated lipid?.

How many fatty acids are found in a lipid?.

Vitamin D (fat is needed to allow this vitamin to assist in calcium absorption.

This is called hydrophobic: water - fearing.

Lipids DO NOT dissolve in water: insoluble.

Plant fats like peanut oil, corn oil, and olive oil.

Animal fats such as butter and bacon grease.

Types of Fatty Acids SATURATED UNSATURATED Lipid Structure Fatty Acid Saturated (straight) Glycerol Fatty Acid Unsaturated (bent) Fatty Acid MONOMERS!

Foods with unsaturated fatty acids are liquid at room temperature.

If there is at least one carbon –carbon double bond in a fatty acid, the fatty acid is unsaturated.

Usually solid at room temperature Carboxyl group.

This means the fatty acid has the most hydrogen atoms it can possibly have.

If each carbon atom in a lipid’s fatty acid is joined to other carbon atoms by only one single bond, the lipid is called saturated.

Through hydrolysis, 3 waters are added to break apart the one Lipid molecule.

Through dehydration synthesis, 3 waters are removed to attach the 3 fatty acids.

ĭehydration synthesis Hydrolysis Ester bond

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

Some produce waterproof coverings on cells and tissues.

Fats, oils, and waxes Adipose Cells Leaf Cuticles Honeycomb Beeswax.

Only have carbon (C), hydrogen (H), and oxygen (O).

Macromolecules that generally do not dissolve in water and are made mostly of carbon and hydrogen atoms.

Recognize the monomers of each group of organic molecules.
