The Nobel Prize in Chemistry 1957 was awarded to Lord Todd "for his work on nucleotides and nucleotide co-enzymes".
 

Nucleotides and nucleotide coenzymes are words that may seem strange and abstruse, but these compounds are of great importance to all of us. The nucleotides have been known for nearly 90 years and they have been frequently studied by both chemists and biologists, but for a long time they were, from the chemist's point of view, an underdeveloped field of research.
