  2. Sympathomimetic drug - Wikipedia

    en.wikipedia.org/wiki/Sympathomimetic_drug

    A primary or secondary aliphatic amine separated by 2 carbons from a substituted benzene ring is minimally required for high agonist activity. The pKa of the amine is approximately 8.5-10. [2] The presence of hydroxy group in the benzene ring at 3rd and 4th position shows maximum alpha- and beta-adrenergic activity. [medical citation needed]

  3. Aromatic amino acid - Wikipedia

    en.wikipedia.org/wiki/Aromatic_amino_acid

    Aromatic trace amines like tyramine can displace norepinephrine from peripheral monoamine vesicles and in people taking monoamine oxidase inhibitors (MAOIs) this occurs to the extent of being life threatening. Blue diaper syndrome is an autosomal recessive disease that is caused by poor tryptophan absorption in the body.

  4. Amino acid - Wikipedia

    en.wikipedia.org/wiki/Amino_acid

    In proteinogenic amino acids, it bears the amine and the R group or side chain specific to each amino acid, as well as a hydrogen atom. With the exception of glycine, for which the side chain is also a hydrogen atom, the α–carbon is stereogenic. All chiral proteogenic amino acids have the L configuration.

  5. Droxidopa - Wikipedia

    en.wikipedia.org/wiki/Droxidopa

    Droxidopa is a prodrug of norepinephrine used to increase the concentrations of these neurotransmitters in the body and brain. [4] It is metabolized by aromatic L-amino acid decarboxylase (AAAD), also known as DOPA decarboxylase (DDC).

  6. Tyramine - Wikipedia

    en.wikipedia.org/wiki/Tyramine

    Notably, it is unable to cross the blood-brain barrier, resulting in only non-psychoactive peripheral sympathomimetic effects following ingestion. A hypertensive crisis can result, however, from ingestion of tyramine-rich foods in conjunction with the use of monoamine oxidase inhibitors (MAOIs).

  7. Triethylenetetramine - Wikipedia

    en.wikipedia.org/wiki/Triethylenetetramine

    The reactivity and uses of TETA are similar to those for the related polyamines ethylenediamine and diethylenetriamine. It is primarily used as a crosslinker ("hardener") in epoxy curing. [ 4 ] [ 5 ] TETA, like other aliphatic amines, react quicker and at lower temperatures than aromatic amines due to less negative steric effects since the ...

  8. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Most aliphatic compounds are flammable, allowing the use of hydrocarbons as fuel, such as methane in natural gas for stoves or heating; butane in torches and lighters; various aliphatic (as well as aromatic) hydrocarbons in liquid transportation fuels like petrol/gasoline, diesel, and jet fuel; and other uses such as ethyne (acetylene) in welding.

  9. Amine - Wikipedia

    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 ...
