DHA is a hygroscopic white crystalline powder. It has a sweet cooling taste and a characteristic odor. It is the simplest of all ketoses and has no chiral center.The normal form is a dimer (2,5-bis(hydroxymethyl)-1,4-dioxane-2,5-diol).
The name is derived from that of quinic acid (with the suffix "-one" indicating a ketone), since it is one of the compounds obtained upon oxidation of quinic acid. [4] Quinic acid, like quinine is obtained from cinchona bark , called quinaquina in the indigenous languages of Peruvian tribes.
p-Dimethylaminobenzophenone is related to Michler's ketone, but with only one amine. [5] Auramine O, a dye, is a salt of the iminium cation [(CH 3) 2 NC 6 H 4] 2 CNH 2 +.Michler's thione, [(CH 3) 2 NC 6 H 4] 2 CS, is prepared by treatment of Michler's ketone with hydrogen sulfide in the presence of acid or sulfideing auramine O. [6] Hydride reduction of Michler's ketone gives 4,4'-bis ...
Ketoacidosis is a metabolic state caused by uncontrolled production of ketone bodies that cause a metabolic acidosis.While ketosis refers to any elevation of blood ketones, ketoacidosis is a specific pathologic condition that results in changes in blood pH and requires medical attention.
“The potential issue with food additives like red dye No. 3 is their association with health concerns, including potential links to hyperactivity in children,” says Daniel Ganjian, M.D., a ...
Anthraquinone, also called anthracenedione or dioxoanthracene, is an aromatic organic compound with formula C 14 H 8 O 2.Several isomers exist but these terms usually refer to 9,10-anthraquinone (IUPAC: 9,10-dioxoanthracene) wherein the keto groups are located on the central ring.
Scientists have used a food coloring dye used in Doritos and other products to create mice with see-through skin, a low-cost way to assess the body's internal operations.
Bradman said some foods containing the dyes aren't eaten as frequently, like ice cream or candy. But the chemicals have made their way into other products that kids eat and drink daily, like juice ...
