Marceli Nencki

Wilhelm Marceli Nencki (1847-1901) was a famous Polish chemist and doctor.


Nencki's main scientific interest concentrated on urea synthesis, the chemistry of purines and biological oxidation of aromatic compounds. He was also interested in the structure of proteins, enzymatic processes in the intestine and 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.
