Lipids

Question 1

Lipid

Answer 1

fatty acids monomers, hydrophobic molecules- fat, oil, phospholipid, cholesterol, hormones, waxes, etc.

Question 2

Fatty Acids

Answer 2

long hydrocarbon (nonpolar H and Cs) with a carboxyl group

Question 3

Amphipathic

Answer 3

molecule has both hydrophobic and hydrophilic areas

Question 4

Steroids

Answer 4

contains a fused ring structure- hydrophobic and insoluble

Question 5

Cholesterol

Answer 5

precursor to steroid hormones, in plasma membrane= affects fluidity and permeability of cell membranes

Question 6

Molecular structure of a triglyceride

Answer 6

3 carbon glycerol molecule bonded by an ester bond to 3 fatty acid chains, fats/oils are triglycerides

Question 7

Saturated

Answer 7

max amount of H on the Cs- can pack together nice= solid at room temp

Question 8

Unsaturated

Answer 8

at least 1 double bond between Cs= kink= harder to pack close together= liquid at room temp

Question 9

cis

Answer 9

unsaturation on the same side of the molecule (H on either side of the double bonds are on the same side), leads to kinked structure= liquid

Question 10

trans

Answer 10

unsaturation on the opposite sides of the molecule (H on either side of the double bonds are on opposite sides), leads to more linear structure= solid
