The bond interaction between Ag n and ammonia is the weakest of all the systems. The bond of the ammonia molecule to the metal clusters can be compared with the pyridine-Mn systems. Both molecules ...

Carbamoyl phosphate synthetase (CPS) is a member of the amidotransferase family of enzymes that uses the hydrolysis of glutamine as a localized source of ammonia for biosynthetic transformations.

Despite their fundamental biological role, the precise molecular architecture of centromeres has remained unclear, with scientists seeking to understand how these regions differ structurally from ...
