lips and proteins

Question 1

what are lipids

Answer 1

long term storage for energy
glycogen build up ➡️ converts extra carbs to fat

Question 2

what carrier is a lipid for

Answer 2

vitamins

Question 3

what material are lipids for

Answer 3

hormone synthesis

Question 4

lipid structure

Answer 4

non polar: can’t dissolve

Question 5

what structural units are lipids formed of

Answer 5

1. glycerol
2. fatty acids
   ( combined with dehydration synthesis)

Question 6

triglycerides

Answer 6

glycerol + fatty acids
Removal of water during synthesis

Question 7

fats

Answer 7

triglycerides that are solid at room temp

Question 8

saturated fats

Answer 8

single bonds between carbon atoms
hard to break down (strong)
comes from animals sources ex. butter

Question 9

oils

Answer 9

triglycerides that’s are liquid at room temperature
unsaturated fats: double bonds between atoms
easily broken down
form plant sources ex. olive oil

Question 10

phospholipids

Answer 10

glycerol and 2 fatty acids
composed of phospholipid bilayer: cell membrane

Question 11

is the head of a phospholipid polar or nonpolar

Answer 11

polar

Question 12

is the tail of a phospholipid polar or nonpolar

Answer 12

nonpolar

Question 13

waxes

Answer 13

long chain fatty acids joined to long chain alcohols of carbon rings that are non polar

Question 14

protein

Answer 14

hemoglobin (carrying o2)
polypeptides folded into 3d shapes

Question 15

what are proteins composed of

Answer 15

carbon
oxygen
hydrogen

Question 16

amino acids

Answer 16

essential amino acids must come from food

Question 17

primary protein structure

Answer 17

unique sequence of amino acids in the chain

Question 18

secondary protein structure

Answer 18

formed by hydrogen bonds between peptide chains

Question 19

tertiary protein structure

Answer 19

bending/folding due to interaction of R groups

Question 20

quaternary protein structure

Answer 20

large proteins
2 or more polypeptides

Question 21

2 polypeptides in quaternary structure are called

Answer 21

dimer

Question 22

4 polypeptides in quaternary structure are called

Answer 22

tetramer

Question 23

proteins fold:

Answer 23

spontaneously to be most stable

Question 24

coagulation

Answer 24

permanent change, can never go back to original form
ex. boiled egg

where is the chemical digestion of lipids? 

Answer 26

small instestine

Question 27

where is the chemical digestion of carbohydrates?

Answer 27

mouth
