Hans von Euler-ChelpinDied 7 Nov 1964 at age 91 (born 15 Feb 1873).Hans Karl August Simon von Euler-Chelpin was a German-Swedish biochemist who shared the 1929 Nobel Prize for Chemistry with Sir Arthur Harden for work on the role of enzymes in the alcoholic fermentation of sugar. In 1904 important work by Arthur Harden had shown that enzymes contain an easily removable nonprotein part, a coenzyme. In 1923 Euler-Chelpin worked out the structure of the yeast coenzyme. He showed that the molecule is made up from a nucleotide similar to that found in nucleic acid. It was named diphosphopyridine nucleotide (now known as NAD). He also worked on vitamins. His son, Ulf von Euler, was also a Nobel prizewinner. |
