Formed in 1955 as the International Union of Biochemistry, the union has presently 77 member countries (as of 2008). IUBMB organizes a triennial Congress of Biochemistry and Molecular Biology, and sponsors more frequent conferences, symposia, educational activities and lectures. It publishes standards on biochemical nomenclature, including enzyme nomenclature, in some cases jointly with the International Union of Pure and Applied Chemistry (IUPAC). IUBMB has instituted the Wood Whelan Research fellowship scheme for budding
