    en.wikipedia.org/wiki/Amine

    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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...

  3. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a ...

  4. Quaternary ammonium cation - Wikipedia

    en.wikipedia.org/wiki/Quaternary_ammonium_cation

    Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.

  5. Benzylamine - Wikipedia

    en.wikipedia.org/wiki/Benzylamine

    Benzylamine, also known as phenylmethylamine, is an organic chemical compound with the condensed structural formula C 6 H 5 CH 2 NH 2 (sometimes abbreviated as PhCH 2 NH 2 or BnNH 2).It consists of a benzyl group, C 6 H 5 CH 2, attached to an amine functional group, NH 2.

    Aminoaldehydes and aminoketones are organic compounds that contain an amine functional group as well as either a aldehyde or ketone functional group. These compounds are important in biology and in chemical synthesis. Because of their bifunctional nature, they have attracted much attention from chemists.

  7. Glutamic acid - Wikipedia

    en.wikipedia.org/wiki/Glutamic_acid

    The change in protonation state occurs at pH 4.07. [11] This form with both carboxylates lacking protons is dominant in the physiological pH range (7.35–7.45). At even higher pH, the amino group loses the extra proton, and the prevalent species is the doubly-negative anion − OOC−CH(NH 2)−(CH 2) 2 −COO −. The change in protonation ...
