Hammarsten

Hammarsten, Olof (born in 1841), an outstanding contemporary Swedish physico-chemist, professor in Uppsala (Sweden). Among the works of H. should be noted his research on the chemistry of mucinous substances, works on blood proteins and exudates, on the mechanism of coagulation of blood and milk, on nucleoalbumins. Particularly remarkable are H's detailed studies on the chemistry of bile and his numerous works on pepsin and rennet enzyme (chymosin), which proved the proteolytic nature of the latter and the independence (non-identity) of both enzymes; this view was long and ardently defended by H. H. became widely known as the author of a very popular textbook of physiological chemistry (Lehrbuch d. physiologischen Chemie, Munich, 1922), which went through many editions and was translated into most European languages, including Russian. H. is chairman of the commission for the Nobel Prize in the field of chemistry (Stockholm). Hammarsten's test for bile pigments, see Bile pigments, Urine.
