Lexicon

The pages listed below comprise a lexicon of key terms and concepts in CAZypedia. Specifically, the aim of the lexicon is to provide a precise definition of various specialized terms unique to carbohydrate chemistry [1, 2], as well as a general overview of the catalytic mechanisms of the major CAZyme classes [3, 4, 5, 6].
