'''Wilhelm Marceli Nencki''' ([[1847]]-[[1901]]) was a famous [[Poles|Polish]] [[chemist]] and doctor.

==Work==

Nencki's main scientific interest concentrated on [[urea]] synthesis, the chemistry of [[purines]] and biological [[oxidation]] of [[aromatic]] [[Chemical compound|compounds]]. He was also interested in the structure of [[proteins]], [[enzymes|enzymatic]] processes in the [[intestine]] and [[bacteria|bacterial]] [[biochemistry]]. One of his achievements was for example demonstration that [[urea]] is formed in the [[organism]] from [[amino acids]] rather than being preformed on a [[protein]] [[molecule]] and that it is accompanied by binding of [[carbon dioxide]].

He proposed that the synthesis of [[fatty acids]] proceeds stepwise, by a gradual [[condensation]] of two-[[carbon]]-[[atom]] fragments and that oxidation of [[fatty acids]] occurs by splitting into two-carbon units.

Among Nencki's greatest achievements was his study on the chemical structure of [[haemoglobin]]. He identified [[haemopyrrole]] among degradation products of haemoglobin and showed its identity with one of the products obtained by [[Leon Marchlewski]] from [[chlorophyll]].
