The first to be identified was the use of NAD + as the ADP-ribose donor in ADP-ribosylation reactions, observed in the early 1960s. Studies in the 1980s and 1990s revealed the activities of NAD + and NADP + metabolites in cell signaling – such as the action of cyclic ADP-ribose , which was discovered in 1987.

In most cases of interest in chemical thermodynamics there are internal degrees of freedom and processes, such as chemical reactions and phase transitions, which create entropy in the universe unless they are at equilibrium or are maintained at a "running equilibrium" through "quasi-static" changes by being coupled to constraining devices, such as pistons or electrodes, to deliver and receive ...

The total energy of a system can be subdivided and classified into potential energy, kinetic energy, or combinations of the two in various ways. Kinetic energy is determined by the movement of an object – or the composite motion of the components of an object – and potential energy reflects the potential of an object to have motion, and generally is a function of the position of an object ...

Mammalian alcohol dehydrogenases also have a structural zinc site. This Zn ion plays a structural role and is crucial for protein stability. The structures of the catalytic and structural zinc sites in horse liver alcohol dehydrogenase (HLADH) as revealed in crystallographic structures, which has been studied computationally with quantum chemical as well as with classical molecular dynamics ...

"I'll Be Home for Christmas" is a Christmas song written by the lyricist Kim Gannon and composer Walter Kent and recorded in 1943 by Bing Crosby, who scored a top ten hit with the song. Originally written to honor soldiers overseas who longed to be home at Christmas time, "I'll Be Home for Christmas" has since gone on to become a Chr
