lipids - formation identification

lipids are hydrophobic because

nonpolar.

lipid types

fats, oils, waxes, and steriods.

based off the formation, what type of lipid is this?

triglyceride - condensation reaction with water forms glycerol molecules and 3 fatty acids

based off the formation, what type of lipid is this?

phospholipid - formed through condensation reaction between one of the carbons in the glycerol molecule and phosphate head.

this is a formation of..?

generalize fatty acid

saturated fat structure

no double bonds between carb molecules —> saturated with hydrogen.

saturated fat physical property

typically solids at room temp. (butter)

unsaturated fat structure

1, 2, or more double bonds between carbons on the chain.

unsaturated fat physical property

liquids at room temp(vegetable oil)

what are cis fatty acids?

unsaturated fats where two hydrogen atoms on the same side of the double bond.

cis bonds are bent or straight?

bent

cis stability

less stable

cis melting point

low

what are trans fatty acids?

two hydrogen atoms on opposite sides of the double bonds.

trans fatty acids bent or straight?

straight

trans fatty acids stability

more stable

trans fatty acids melting point

higher due to stacking

what type of fatty acid?

unsaturated

what type of fatty acid?

saturated

what type of fatty acid? what type of fatty acid?

trans

triglycerides are used for

long term energy storage(adipose tissue)

adipose tissue is useful for

thermal insulation. (fat keeps you warmer)

phospholipids form

bilayer

the image shows examples of?

steroids

steroids can slip through the phospholipid bilayer due to their

mostly hydrocarbon and hydrophobic properties.
