Which indicator which was definitely D Bromophenol Blue

[10weid]

yepp!
umm 15 i got also got B, which was that question?

[kenhung123]

I think it was thymol blue because it should change colour after equivalence point

[Studyinghard]

was 15 the amino acid insulin question. fkn it was 49 and not 50! i got trickeddddddddd big time.

[crayolé]

FARRR
I got the right answer for 1, i circled the wrong box :@

^^^How was it 49? :/^^^

[kenhung123]

Hmm...apparently with the insulin one the number of peptide links is 49 because insulin is made of 2 strands??? Can someone confirm this? Did the question actually say insulin was made of 2 strands because I don't remember seeing that.

Hmm it said 1 molecule of insulin...and it said how many peptide in 1 molecule and 1 molecule had 51 amino acids

[10weid]

one molecule contains trwo polypeptide chains
meaning that there are 51-2 peptide links = 49 peptide links

[Studyinghard]

I KNOW WTF IT SAID ONE MOLECULE. and people are saying 2 strands? was there 2 strands in the question? If so then 49 is right but i remember seeing 1 strand. :S

[10weid]

two stanrds, connected by disulfide bridges..

i defs don't remeber seeing two strands.........

[Studyinghard]

There are 2 strands. FCK!

can someone confirm if 4 MC is C?

If MC 4 is C then I got 18/20.

[10weid]

yeh it's c

[Benny1234]

the question did say there were two strands. Each strand would have one less peptide link than amino acid so its 51 minus 2 = 49

Yeah, it's a subtle distinction.
