Hydrogen gas, H2, reacts with nitrogen gas, N2, to form ammonia gas, NH3, according to the equation. 3H2(g)+N2(g)â2NH3(g) a. How many moles of NH3 can be produced from 18.0 mol of H2 and excess N2?
Glutamine: A Conditionally Essential Amino Acid. Glutamine is a non-essential amino acid under normal conditions, meaning the body is able to produce enough to meet its own requirements. Glutamine becomes essential during certain physiological states, which is why it is termed a 'conditionally essential' amino acid 2.
The enzyme Î³-glutamyl transferase (GGT) cleaves C-terminal glutamyl groups from amino acids and transfers them to another peptide or to an amino acid. It is important in glutathione metabolism, amino acid absorption and protection against oxidant injury.
