The most important carriers of hydrogen in catabolic reactions [are] NADH and NAD+.... The part of the NAD+ molecule known as the nicotinamide ring is able to accept a hydrogen atom together with an additional electron (a hydride ion, H-), forming NADH. In this reduced form, the nicotinamide ring has a reduced stability because it is no longer stabilized by resonance. As a result, the added hydride ion is easily transferred to other molecules. In the biological oxidation of a substrate molecule such as an alcohol, two hydrogen atoms are lost from the substrate. One of these is added as a hydride ion to NAD+, producing NADH, while the other is released into solution as a proton (H+) 3, record 1, English, - hydrogen%20carrier
