ECHEMI Editorial Reference

Colorless to pale yellow, clear, viscous liquidChEBI: An organic disulfide that consists of two molecules of pantothenic acid linked by amide bonds to a cysteamine disulfide bridging group.
Bis(N-pantothenylamidoethyl) disulfide is an organonitrogen compound and an organooxygen compound. It derives from a beta-amino acid.
D-Pantethine is a compound in which two molecules of D-pantetheine bind through an S-S linkage. D-Pantethine is available from commercial sources as well as from D-pantothenic acid. It is known that the sulfhydryl group is the metabolically active part of the molecule. Coenzyme A is an essential cofactor in over 70 biological pathways, such as fatty acid oxidation, carbohydrate metabolism, and amino acid catabolism. Studies conducted in vitro suggest that D-Pantethine inhibits the activity of aldehyde dehydrogenase; however, related metabolites of the compound, such as Taurine (sc-202354), D-pantetheine, Coenzyme A, and D-pantothenate activate this enzyme.
Colorless to pale yellow, clear, viscous liquid
Moderately toxic by intravenous route. An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of SOx and NOx.
