Dude The premed biochemistry TA's were like androstene-3,17-diones 4-ene will be resonanance stabilized using dmso thus preventing the reaction of the fatty acid with the 3 position and it will go strait to the 17 position with heat. 15yrs ago.
and some were like I've designed 1000's of peptide derivatives.
1000's of designer peptides bro any sequence there is bro.
