the porcine neuropeptide y ( npy ) , a 36-residue peptide amide , was synthesized by assembling six peptide fragments followed by thioanisole-mediated deprotection with trifluoromethanesulfonic acid in trifluoroacetic acid . beta-cycloheptyl aspartate , asp ( ochp ) , was employed to suppress base-catalyzed succinimide formation .
