Hydrogen is the most abundant element in the universe. If you burn it in a fusion reaction, you get helium, and lots of energy. This reaction, which takes place in the sun, is responsible for sustaining life on earth.

The mechanism of hydrogen incorporation into fatty acids was investigated with an enzyme preparation from baker's yeast. Fatty acids synthesized from malonyl-CoA and acetyl-CoA in the presence of D2O or stereospecifically deuterium-labeled NADPH were isolated and analyzed by mass chromatography to examine the localization of deuterium atoms in the molecule. The following results were obtained:
Hydrogen atoms from water were found on the even-numbered methylene carbon atoms (2-hydrogen atoms per carbon atom). The second hydrogen atom was incorporated as the result of hydrogen exchange phenomenon between the methylene group of malonyl CoA and water.
HB hydrogen of NADPH was used for Ã-ketoacyl reductase.
HB hydrogen of NADPH was also used for enoyl reductase.
Hydrogen atoms from HB position of NADPH were found on the odd-numbered methylene carbon atoms (2-hydrogen atoms per carbon atom).

It is the seperation of water. Spliting the atoms and puting them back together again, I believe.
