In 1883 he was appointed extraordinary professor and, in 1884, ordinary professor at the University of Prague by the Emperor, and was the rector of the same university for a time. He is particularly known for his contributions in organic chemistry and biochemistry. He was the first to synthesise uric acid from glycine in 1882. He also noticed that aminoacids were building blocks of proteins. Horbachevsky worked in Austria, Czechoslovakia, Hungary and Ukraine.
