Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9] Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names.
Examples are dopamine, norepinephrine and serotonin. All monoamines are derived from aromatic amino acids like phenylalanine, tyrosine, and tryptophan by the action of aromatic amino acid decarboxylase enzymes. They are deactivated in the body by the enzymes known as monoamine oxidases which clip off the amine group.
Substance P (SP) is an undecapeptide (a peptide composed of a chain of 11 amino acid residues) [1] and a type of neuropeptide, belonging to the tachykinin family of neuropeptides.
For example, the industrial production of chloroethane proceeds by the reaction of ethylene with HCl: [citation needed] H 2 C=CH 2 + HCl → CH 3 CH 2 Cl. In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O.
For example, one pathway may be responsible for the synthesis of a particular amino acid, but the breakdown of that amino acid may occur via a separate and distinct pathway. One example of an exception to this "rule" is the metabolism of glucose .
“Speaking of Synthesis means approaching the guiding principle of Assagiolian psychology, both the means and the goal of the entire psychosynthetic pathway. . . Synthesis is a process that involves the creation of a relationship between two or more elements through a third entity, in order to create a new reality. [5]
For example, LTP in the Schaffer collateral pathway of the hippocampus is NMDA receptor-dependent - this was proved by the application of AP5, an antagonist to the NMDA receptor, which prevented LTP in this pathway. [23] Conversely, LTP in the mossy fiber pathway is NMDA receptor-independent, even though both pathways are in the hippocampus. [24]
A common example of an indolamine is the tryptophan derivative serotonin, a neurotransmitter involved in mood and sleep. [1] Another example of an indolamine is melatonin. In biochemistry, indolamines are substituted indole compounds that contain an amino group. Examples of indolamines include the lysergamides.
