Transcript of CGHS Biology - Macromolecules: Lipids

LIPIDS:
Fats and Oils

Fats - A protective cell cover
Cell Membranes are made of fats
Parts of a Lipid
Monomer = glycerol and fatty acids
LIPIDS
Fancy word for fats,
oils, waxes, phospholipids,
steroids, and cholesterols
Cholesterol
A lipid with a ring structure (remember the 3 types of structures from yesterday
Functions of a Lipid
Fats and oils provide
long-term energy storage.
Fats provide insulation
1) Non-polar (don't mix with
water) molecules
2) Like carbohydrate, lipids
are made of C, H, and O
What are lipids?
Two types of Fatty Acids
Saturated Fatty Acids - come from animals
All the hydrogen bonds are full
No double bonds between the carbons
Unsaturated Fats - come from plants
Not all the hydrogen bonds are full
No double bonds are present
Critical Thoughts:
Fats and oils are similar, but why are animal fats solid and plant oils liquid?
The double bonds in unsaturated fats make kinks in the fatty acids.
This prevents molecules from being packed tightly into a solid.
Polar “head” and Non-Polar fatty acid “tail”
Polar head is hydrophilic (water-loving)
Non-Polar tail is hydrophobic (water-hating)
This fat is call as phospholipid
In cells there are two of these
phosolipid layers
The Good, the Bad, the Ugly
Including estrogen, cortisone, testosterone, and Vitamin D
Also called steroids...
regulate various physiological functions in the body.
