4-Androstene-3,6,17-trione (4-AT; also marketed as 6-OXO or 4-etioallocholen-3,6,17-trione) is a drug or nutritional supplement that may increase the testosterone-estrogen ratio, but has no proven effect on body composition. Its use can be detected in urine.
Fluorexetamine (3'-Fluoro-2-oxo-PCE, 3-FXE) is a recreational designer drug from the arylcyclohexylamine family, with dissociative effects. It has reportedly been sold over the internet since around 2017, though has remained relatively uncommon.
In enzymology, a 3-oxosteroid 1-dehydrogenase (EC 1.3.99.4) is an enzyme that catalyzes the chemical reaction. a 3-oxosteroid + acceptor a 3-oxo-Delta 1-steroid + reduced acceptor. Thus, the two substrates of this enzyme are 3-oxosteroid and acceptor, whereas its two products are 3-oxo-Delta1-steroid and reduced acceptor.
Erythrosine, also known as Red No. 3, is an organoiodine compound, specifically a derivative of fluorone. It is a pink dye which is primarily used for food coloring. [2] It is the disodium salt of 2,4,5,7-tetraiodofluorescein. Its maximum absorbance is at 530 nm [3] in an aqueous solution, and it is subject to photodegradation.

In organic chemistry, keto acids or ketoacids (also called oxo acids or oxoacids) are organic compounds that contain a carboxylic acid group (−COOH) and a ketone group (>C=O). [1] In several cases, the keto group is hydrated. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in ...
Hydroformylation of an alkene (R 1 to R 3 organyl groups (i. e. alkyl-or aryl group) or hydrogen). In organic chemistry, hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes (R−CH=O) from alkenes (R 2 C=CR 2).
Interactions between carbonyl groups and other substituents were found in a study of collagen. [3] Substituents can affect carbonyl groups by addition or subtraction of electron density by means of a sigma bond. [4] ΔHσ values are much greater when the substituents on the carbonyl group are more electronegative than carbon. [4] A carbonyl ...
