1.Hab cusub oo loogu talagalay kobcinta ninhydrin ama 1,8-diazafluoren-9-one (DFO) -daaweeyay faraha dahsoon ee warqada kulaylka ayaa lagu sifayn doonaa.Inta badan sagxadaha heerkulbeegga ee xaashida kulaylka ayaa noqda mugdi marka lagu daweeyo DFO ama ninhydrin petroleum ether (NPB).Saamayntani waxay yaraynaysaa kala duwanaanshaha u dhexeeya faraha la horumariyay iyo asalka.Habka cusub ee lagu sharraxay wuxuu yareeyaa wasakhayntan mugdiga ah iyada oo aan meesha laga saarin lakabka kulaylka iyo qaybo ka mid ah faraha horumarsan, sida ku dhacda dhaqidda acetone.Habka cusub, faraha la horumariyay waxay u muuqdaan kuwo fiiqan iyo kala duwanaansho sare.Tijaabooyin ballaaran ayaa la sameeyay, taasoo keentay xal shaqo oo la hagaajiyay, kaas oo ku dallaca warqadda ugu yar ee kiimikooyinka, waa mid raqiis ah, awoodna u siinaya tiro badan oo waraaqo ah in lagu daweeyo waqti gaaban.Xalka shaqadu wuxuu ka kooban yahay ganacsi ahaan la heli karo, aan isbeddelayn, xeryahooda dabiiciga ah ee nitrogenous waxaana loo isticmaali karaa sida codsiga xalka NPB iyadoo la dhex gelinayo.

2. Warqadani waxay qeexaysaa daraasadda falcelinta u dhaxaysa 1, 8-diazafluoren-9-one (DFO) oo leh amino acid L-alanine ee khamriga methyl.Dulsaar gaar ah ayaa la siiyay doorka suurtagalka ah ee dareeraha kaas oo u muuqda inuu la falgalo DFO si loo sameeyo hemiketal kaas oo ah noocyada falcelinta.Dariiq falcelin suurtagal ah ayaa la soo jeediyay iyadoo lagu salaynayo xogta hadda la ururiyay.Dhexdhexaadiyaha falcelinta iyo alaabooyinka waxaa lagu aqoonsaday habab kala duwan oo spectroscopic ah oo ay ku jiraan spectrometry mass spectrometry (MS), resonance magnetic nuclear (NMR) spectroscopy, iyo x-ray crystallography.
