1

largely nonpolar compounds that are insoluble in water

lipids

2

Lipids are composed of ?

fatty acids

3

fatty acid structure

carboxylic acid polar head. hydrocarbon nonpolar tail.

4

shorter chain length and unsaturation ? melting temperature of fatty acid

decreases

5

Cause kinds in hydrocarbon tails of fatty acids

cis double bonds

6

? fat correlates w/ heat disease

trans

7

Optimal fatty acid charactersitics for tight packing

long chain, few kinks

8

triacylglycerolstructure

fatty acid triester of glycerol. Three fatty acid chains bound to a glycerol.

9

fatty acids linked by ? linkage

ester

10

function of triacylglycerol

fatty acid storage as an energy reserve

11

major constituents of cell membrane

phospholipids

12

micelles

spheres with polar heads facing outward toward water and hydrophobic tails facing inward

13

phospholipid structure

fatty acids bound to two carbons of glycerol. Phosphate with hydrophilic group bond to third carbon

14

fatty acids form ? in water

micelles

15

Triglycerides form this in water

large spherical fat droplets

16

Phospholipids and glycolipids form this in water

bilayer

17

steroids are made from these subunits

ispoprenes

18

two common steroids

cholesterol, testosterone

19

most abundant steroid in animals

cholesterol

20

steroid that is a major component of animal membranes

cholesterol

21

cholesterol is a ? due to a hydroxyl group at its third carbon

sterol

22

combination between lipids and carbohydrates

glycolipids

23

glycolipid structure

carbohydrates are linked to polar head of amphipathic molecule
