B1.1 (lipids and glycoproteins)

Question 1

hydrophobic things in non polar

Answer 1

solvents can dissplve things

due to similar properties

Question 2

triglycerides

Answer 2

are consumed in food and can be synthesises by the liver

they are found in butter

usually solid at rtm

formed by condensation of 1 glycerol and 3 fatty acids

Question 3

every time fatty acids joins

Answer 3

h2o is released, ester bomds form between glycerol and fatty acid

Question 4

wax and steroids

Answer 4

lipid, insoluble in h2o high melting point (waxy cuticle)

lipids, made of 4 CARBON RINGS fused together

Question 5

alpha vs beta glucose

Answer 5

alpha OH BOTH on the bottom

beta OH on one bottom, one top

Question 6

formation of polysaccharides

Answer 6

monosaccharieds are joined by glysocidic bonds

we name these according to the carbons (1,4 chain of amylose, 1,4 and 1,6 chain of amylopectin)

Question 7

branches give starch

Answer 7

more effective storage

Question 8

cellulose is made of

Answer 8

beta glucose spo will form strong fibers,

this glycosidic bond alternates /inverts (pointing up and down)\

CH2OH HH. oh OH OH
oh OH OH Ch2oh HH

Question 9

amylopectin and glycogen have

Answer 9

alpha 1,4 and 1,6 glycosidic bonds

(only ones which have 1,6 which makes them branched, more efffective storage (sa) and compact )

HIGH ENERGY DENSITY

Question 10

aternative ch2oh groups in cellulose means that

Answer 10

H bonds form between asjacent cellulose to form strong microfibrils

Question 11

why polysacchaids are good storage molecules

Answer 11

1. branching of glycogen and amylopectin (starch) makes molecules compact to fit more
2. insoluble (cause are large) son are easier to be stored in 1 location and dont affect osmoregulation
3. polysaccharides are easily hydrolysed (broken down)

Question 12

monosaccharies are

Answer 12

small
sweet
soluble

Question 13

disaccharies are

Answer 13

small
less sweet
soluble

Question 14

polysaccharied are

Answer 14

large
not sweet
insoluble

Question 15

antigen is a

Answer 15

foreing or self antigen

it is a glycoprotein outside of cell

Question 16

glycoprotein is a

Answer 16

molecules made of monosaccharied and amino acids

has a carb and protein component

Question 17

glycoproteins can be used as a receptor

Answer 17

for hormones and neurotransmitters, like com drugs or when insulin arrives at a call, and it binds with a glycoprotein and indicates the cell responses to the hormones

Question 18

glycoproteins will affect red

Answer 18

blodd cell group since they are on top and have a diffrent shape for A B AB or O

these are self antigens

if the wrong blood type is transfuses, the proteins in the plasma join to the antigen and cause clotting
