The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile).

These include vascular smooth muscle relaxation, resulting in arterial vasodilation and increasing blood flow. [4] NO is also a neurotransmitter and has been associated with neuronal activity and various functions such as avoidance learning. NO also partially mediates macrophage cytotoxicity against microbes and tumor cells.
The nitrile reacts with the catalytic active serine and forms an imidate adduct. DPP-4 inhibitors usually have an electrophilic group that can interact with the hydroxyl of the catalytic serine in the active binding site (Figure 3). Frequently that group is a nitrile group but can also be boronic acid or diphenyl phosphonate.
Dentist wearing nitrile gloves Medical gloves are disposable gloves used during medical examinations and procedures to help prevent cross-contamination between caregivers and patients. [ 1 ] Medical gloves are made of different polymers including latex , nitrile rubber , polyvinyl chloride and neoprene ; they come unpowdered, or powdered with ...
In enzymology, an aliphatic nitrilase also known as aliphatic nitrile aminohydrolase (EC 3.5.5.7) is an enzyme that catalyzes the hydrolysis of nitriles to carboxylic acids: R-CN + 2 H 2 O ⇌ {\displaystyle \rightleftharpoons } R-COOH + NH 3
Blood pressure plummets; the brain and muscles are starved of oxygen. If this happens repeatedly, the heart thickens and stop working. Perhaps not surprisingly, some dialysis patients say they ...
Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower.
Nitrile hydratase and amidase are two hydrating and hydrolytic enzymes responsible for the sequential metabolism of nitriles in bacteria that are capable of utilising nitriles as their sole source of nitrogen and carbon, and in concert act as an alternative to nitrilase activity, which performs nitrile hydrolysis without formation of an intermediate primary amide.
