Fat form is solid or a semisolid
Fat form is mainly found in animals
Oil form is a liquid
Oil form is mainly in plants
Found mainly in animals.
Composed of three fatty acids and a glycerol.
Saturated & unsaturated fats
Waxes
Waxes are used to coat and protect things in nature.
Fats and Oils
Steroids

How are they used today:
Many bodybuilders and athletes used steroids to build muscle.
used in necessary medicines.
Help with acne
used as muscle relaxers if your hurt
.

Fat Molecule

Examples:
Plants use waxes to stop evaporation of water from their leaves.
Your ears make wax to protect the inside of your ear.
Bees use wax to make honeycombs.
Wax Molecule
Lipids are made of:
The elements carbon, hydrogen, oxygen
What are lipids made of?
Some even contain nitrogen and phosphorus
Long chains of fatty acids
Monomers & Assembly
Monomers: glycerol and fatty acids
Lipids assemble by attaching to one or more amino acids
Saturated Fats
Unsaturated fats
Phospholipids
Steroid Molecule
Made from glycerol, which are two fatty acids and a phosphate group
Vitamins
Soluble in water and oil
Vitamin A
Vitamin D
Vitamin E
Vitamin K
Helps with eyesight & skin health
Found in: bright yellow and orange fruits, carrots, pumpkins, broccoli, spinach
Phospholipid Example
Phospholipids
Found in: green, leafy vegetables, brussel sprouts, and broccoli
Used for clotting blood
Applied to skin to remove any unusual markings
Sources
Found in sunlight
Treats skin conditions, boosts immune system
Found in vegetable oil, cereal, animal products, fruits, and vegetables
Used in extremely underweight premature babies
Consists of tryglycerides
No double bonds between the carbon atoms
At least one double bond in the chain
Monounsaturated if one double bond
polyunsaturated fat if two or more double bonds
An example of a phosophlipid is a egg yolk.
