An organism belonging to Pseudomonadaceae and capable of utilizing 3-hydroxy-3-methylglutarate as sole carbon source has been isolated from soil. Whole-cell preparations catalyze the oxidation of acetoacetate, acetate, glyoxylate, and citric acid cycle intermediates. Cell-free extracts of 3-hydroxy-3-methylglutarate-grown cells show an adenosine triphosphate, coenzyme A (CoA), and Mg(2+)-depend...

Carbonaceous meteorites deliver a variety of organic compounds to Earth that may have played a role in the origin and/or evolution of biochemical pathways. Some apparently ancient and critical metabolic processes require several compounds, some of which are relatively labile such as keto acids. Therefore, a prebiotic setting for any such individual process would have required either a continuou...

?Weight to go? for questioning these claims, especially as they seem "too good to be true." Hydroxy citric acid (HCA), a modified form of citric acid, is commonly used as a ?fat burner? [2] in many weight loss supplements. It?s derived from the Garcinia cambogia (G. cambogia), a fruit-bearing tree found Asia, Africa, and the Polynesian islands. HCA is believed to inhibit lipogenesis (the metabo...

A model solution of orange juice was prepared and stored. Factors affecting browning and formation of such decomposition products as 3-hydroxy-2-pyrone (3OH2P), 5-hydroxymethylfurfural (HMF), furfural, 5-hydroxymaltol, and 2-furoic acid were examined. Ascorbic acid (AsA) was essential for browning, which was stimulated by amino acids and citric acid, and repressed by chelators and radical scave...

Matract-Polyphenok condens with 2-methylbut-3cne-2-d or y,ydimethylallyl alcohol in 5% aqueous citric acid solution to yield phenolic 2Jdimethylchromans These facik condensation provide chemical support for the biogenetic theory of C-isopentenylation of phenols by 7,7dimcthylallyl pyrophosphate. Iso-psoralidin (20) has been synthesized from 7-hydroxy-2Jdimethylchroman (12) by a novel and conven...

a study was carried out to investigate the effects of organic acid mixture as well as two methionine supplements on performance, carcass characteristics and weight of gastrointestinal tract in broiler chickens. six hundred unsexed day-old ross 308 broiler chicks were utilized in a factorial arrangement of treatments (3×2) based on completely randomized design (crd) of 4 replicates of 25 chicks ...
