Pirolisin
Pirolisin (lambang Pyl atawa O;[1] anu dikode ku stop kodon UAG) nyaéta asam α-amino anu dipaké dina biosintésis protéin dina sababaraha archaea jeung baktéri métanogenik;[2][3] teu aya di manusa. Pirolisin ngandung hiji gugus α-amino (wangun kaprotonan –NH+3 dina kaayaan biologis), hiji gugus asam karboxilat (wangun deprotonasi –COO− dina kaayaan biologis). Ranté gigir pirrolin-na sarupa jeung dina lisin, watekna basa jeung boga muatan positip dina pH nétral.
