Lord Alexander R. Todd

Born 2 Oct 1907; died 10 Jan 1977 at age 69.Baron Alexander R(obertus) Todd (of Trumpington) was a British biochemist whose research on the structure and synthesis of nucleotides, nucleosides, and nucleotide coenzymes gained him the 1957 Nobel Prize for Chemistry. Nucleotides - found in the chromosomes of the cell-kernels, also in cell plasma - are connected with the units of heredity. In combination with proteins they constitute the virus molecules and many coenzymes are nucleotides of low molecular weight but with a special structure. It was known that they are built up of three quite different "building stones": phosphoric acid, a sugar, and a heterocyclic base containing nitrogen, assembled in one macromolecule. Todd researched how they are connected to each other.
