This subclass contains dehydrogenases that act on primary alcohols, secondary alcohols and hemi-acetals. Sub-subclasses are based on the acceptor: NAD+ or NADP+ (EC 1.1.1), a cytochrome (EC 1.1.2), oxygen (EC 1.1.3), a disulfide (EC 1.1.4), a quinone or similar compound (EC 1.1.5), or some other acceptor (EC 1.1.99).
