The invention relates to sustained-release preparations that contain at least one compound of formula I, for the controlled release of an aldehyde or ketone together with an alcohol and a carboxylic acid, wherein it is in the released aldehydes or ketones to organoleptic substances, in particular...
Gluconic acid is produced by oxidizing the aldehyde group of glucose with either bacteria or filamentous fungi [7]. It is a strong chelating agent widely used in foods and various industrial products. Table 1 summarizes the industrial applications and market sizes of these carboxylic acids. Table ...
An efficient synthesis of rac-trichostatic acid (1) and its analogues is reported starting from a commercially available aldehyde. Further manipulations of... A Chatterjee,J Richer,T Hulett,... - 《Organic Letters》 被引量: 19发表: 2010年 ...
Bacterial luciferase catalyses the oxidation of a flavin mononucleotide using molecular oxygen to form an intermediate peroxide, which then reacts with an aliphatic aldehyde (that is produced by the protein products of luxCDE). This reaction produces light, which can then be quantified via ...
Drugs (gemfibrozil 1aa, naproxen 1ab, and fenofibric acid 1ac) were also tested under the standard conditions, delivering the amination products in good yield; and again, the aldehyde was also isolated from the reaction of 1ac and 2a (see SI). Bio-renewable lignin 1ad also underwent the ...
3a, b. Certain osteoblast-related genes, such as NOTCH-regulated ankyrin repeat protein (NRARP), aldehyde dehydrogenase 3 family member A1 (ALDH3A1), and Multimerin 1 (MMRN1), were significantly differentially expressed. Gene ontology (GO) biological process analysis demonstrated that three ...
In this review, we highlight the current state and conversion potential of C1feedstocks to oxo chemicals using isobutyraldehyde as an example. Isobutyraldehyde is a representative oxo aldehyde that serves as a platform chemical for producing a large portfolio of bioproducts including alcohols, acids ...
Another approach used hydrazide-modified gold films, where the hydrazide reacted with the terminal aldehyde group of the carbohydrates [58]. A similar approach employed amine-functionalized surfaces and the coupling of the carbohydrates took place by reductive amination [59–60]. A simple method for...
A 2-ODD has been identified as catalyzing the oxidation of the C-7 group of GAs from an aldehyde to a carboxylic acid in the endosperm of Cucurbita maxima and the embryos of Hordeum vulgare (Fig. 6).48,49 Curiously, both species also have a P450-dependent monooxygenase capable of catalyzi...
In the first step, alcohol groups from ethylene glycol (EG) were oxidized in the presence of nitrate ions to the aldehyde and then to diglycolic acid. In the second step, NaOH was used as a hydrolysis agent. Substitution of hydroxyl groups in nitrate ions formed gadolinium hydroxide (Gd(OH...
