Ascorbic Acid Dehydroascorbic Acid C6 Dicarboxylic Acid
Dehydroascorbic acid is shown to be converted to 2-(threo-l,2,3-trihydroxypropyl)tartronic acid in aqueous alkaline solutions. The structure of the acid was determined by mass spectrometry of its acyclic Me3Si derivative. Mass spectrometric and chromatographic data are compared with those of related compounds. The acid is formed by a benzilic acid rearrangement of the intermediate 2,3-hexodiulo...
متن کامل2,2′-Bipyridine-5,5′-dicarboxylic acid
The title mol-ecule, C(12)H(8)N(2)O(4), lies on an inversion center. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect mol-ecules into one-dimensional chains along [11].
متن کاملcis-Cyclohexane-1,4-dicarboxylic acid
In the title compound, C(8)H(12)O(4), the two carboxyl groups are on the same side of the cyclohexane ring and the ring adopts a chair conformation. Adjacent mol-ecules related by an inversion centre are linked by pairs of O-H⋯O hydrogen bonds, forming a zigzag chain along [1].
متن کاملC4-Dicarboxylic acid cycle and Salmonella typhi.
Several papers have already been published for answering the question whether or not the tricarboxylic acid cycle or the C4-dicarboxylic acid cycle plays a role in microorganisms, and a summarizing description of the subject is seen in Ajl's article(1). Karlson and Barker(2), for example, stated that the tricarboxylic acid cycle does not operate in Azotobacter agilis, Barron, Ardao and Hearon (...
