Functions
True/False
Are lipids heat insulators
True
True or False in saturated lipids are all carbons saturated with nitrogen bonds?
False, they are saturated with hydrogen bonds
An example of lipid
Gasoline is not a lipid
True/False
Phospholipids have a polar head and non-polar tail
True
What type of fat are testosterone and estrogen
Steroids
The name of the lipid that is solid at room temperature.
The name of the lipid that is liquid at room temperature
Saturated and Unsaturated respectively
The good fat
unsaturated fat
All steroids have what for their chemical structure backbone
4 carbon rings
What are the products that cholesterol creates/transforms into
They are a component of the cell membrane
They are the building blocks to acids and hormones
What type of chain do fatty acids have
Hydrocarbon Chain
What cartoon character represented phospholipids
The one who will build what
Heads or Tails which is the non polar in phospholipids
Tails
How energy efficient are lipids compared to carbohydrates
Roughly 2x more energy dense
COOH
Where can you find saturated fats
Meat
What molecules can pass through the phospholipid bilayer
Small non polar molecules
Why do the phospholipids positioned with their tail pointing inwards while the head points outwards.
The polar heads repel other polar molecules acting as a filter. While smaller and non-polar molecules move pass and are attracted to the non-polar tails
How does Triglycerides form
Forms when glycerol connects with 3 fatty acid molecules
The backbone of steroids
Cholesterol
What is a phospholipid made of
Glycerol, Phosphate group and 2 fatty acids
