NH2 or similar may refer to: Azanide (chemical formula NH − 2) Amino radical (chemical formula NH • 2) Nitrenium ion (chemical formula NH + 2) Primary amide group (chemical formula -NH 2) National Harbor–Alexandria Line (Route NH2), a WMATA bus line between Alexandria, Virginia and Prince George's County, Maryland; National Highway 2 (India)
In chemistry, the amino radical, ·NH 2, also known as the aminyl or azanyl, is the neutral form of the amide ion (NH − 2).Aminyl radicals are highly reactive and consequently short-lived, like most radicals; however, they form an important part of nitrogen chemistry.
Azanide is the IUPAC-sanctioned name for the anion NH − 2.The term is obscure; derivatives of NH − 2 are almost invariably referred to as amides, [1] [2] [3] despite the fact that amide also refers to the organic functional group – C(=O)−NR 2.
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 170°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
2′-NH 2-MPTP, also known as 2′-amino-MPTP, is a monoaminergic neurotoxin that was derived from MPTP and is used in scientific research to lesion brain monoaminergic systems in animals.
A nitrenium ion (also called: aminylium ion or imidonium ion (obsolete)) in organic chemistry is a reactive intermediate based on nitrogen with both an electron lone pair and a positive charge and with two substituents (R 2 N +).
The N-terminus is the first part of the protein that exits the ribosome during protein biosynthesis.It often contains signal peptide sequences, "intracellular postal codes" that direct delivery of the protein to the proper organelle.
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C 2 H 4 (NH 2) 2.This colorless liquid with an ammonia-like odor is a basic amine.It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. [6]
