Alexander Ellinger

Alexander Ellinger (17 April 1870, Frankfurt am Main – 26 July 1923, Frankfurt am Main) was a German chemist and pharmacologist.

From 1887 he studied chemistry at the University of Berlin under August Wilhelm von Hofmann and at the University of Bonn as a pupil of August Kekulé. Afterwards, he studied medicine at the University of Munich, followed by work as an assistant in the institute of pharmacology at the University of Strasbourg. In 1897 he became an assistant to Max Jaffé in the laboratory of medicinal chemistry and experimental pharmacology at the University of Königsberg. In 1914 he was appointed professor of pharmacology at the newly established University of Frankfurt.[1]

He is remembered for his extensive biochemical research of several amino acids, especially tryptophan.[2] In 1904 he isolated kynurenic acid from the urine of dogs that had been fed tryptophan.[3] His other work included studies on the water exchange between body tissues and blood, on the formation on lymph,[1] and with chemist Karl Spiro, he conducted investigations of blood coagulation.[4]

gollark: Probably both work to some extent for different people.
gollark: It's not really "motivated" as much as "don't hate it enough to go through the social awkwardness of going through the process of switching options", though.
gollark: I can't get motivated to exercise without being required to by school (since I picked "fitness" as one of my sports options), since it's one of those things I probably should do but don't like doing.
gollark: that moment when you actually do regular exercise at home(other people do, I mean)
gollark: I don't see myself doing that, since I basically only do exercisey things through a combination of being required(ish) to due to picking "fitness" as one of my sport options, some concern for my health, and the fact that it's in the sport-y environment at school and during a timeslot when there aren't really many other options.
