So in this question they ask draw the 20 common amino acids and group them accordingly.
00:11
20 common amino acids according to their group their groups are a amino acid with electrical charge sides and amino acid with electrically charge side chain charge side change are c -o -h -h -h -n -h -n -h -2 ch2 ch2 ch2 nh -nh -2 double bond nh2 plus then coeh this is called arginine in bracket r then c -o -h h, h, nh2, then ch2, nh, histidine, in bracket, h, then next coh, h, h, nh3 plus, lysin, in bracket, k.
03:06
So, these are positive amino acids.
03:19
These three are positive sides and positive positive then negative one negative amino acids coh h and h2 then ch2 coo minus then coh hnh2 co minus then coh hnh2 ch2 c2 co minus so this is asperic acid aspartic acid d this is glutamic acid in bracket e amine acid with polar uncharged side chain amino acid with polar uncharge, uncharge, side chain, side chain.

So, coh, h and h2, ch2 oh, serene, s...
