The 4 substrates of this enzyme are (4-hydroxyphenyl)ethan-1-one, NADPH, H +, and O 2, whereas its 3 products are hydroquinone acetate ester, NADP +, and H 2 O. This enzyme belongs to the family of oxidoreductases , specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen.

Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
The Wolff–Chaikoff effect is subject to an escape phenomenon that limits its action after several days. It is to be distinguished from the Plummer effect, which inhibits the proteolysis of thyroglobulin and the release of pre-formed thyroid hormones from follicles. [14] Both effects operate on different time scales. [14]
The Appel reaction is an organic reaction that converts an alcohol into an alkyl chloride using triphenylphosphine and carbon tetrachloride. [1] The use of carbon tetrabromide or bromine as a halide source will yield alkyl bromides, whereas using carbon tetraiodide, methyl iodide or iodine gives alkyl iodides.
The firing of an action potential, and consequently the release of neurotransmitters, occurs by this gating mechanism. In synaptic gating, in order for an action potential to occur, there must be more than one input to produce a single output in the neuron being gated. The interaction between these sets of neurons creates a biological AND gate. [1]
