Saccharides are better known as carbohydrates (literally hydrates of carbon). Relatively complex carboyhydrates are known as polysaccharides.The simplest carbohydrates are monosaccharides, which are small straight-chain aldehydes and ketones with many hydroxyl groups added, usually one on each carbon except...
Short-chain aliphatic epoxides and ketones are two classes of toxic organic compounds formed biogenically and anthropogenically. In spite of their toxicity... SA Ensign,FJ Small,JR Allen,... - 《Archives of Microbiology》 被引量: 142发表: 1998年 The Catalytic Activity of Four Expressed Human ...
etc., is laying the groundwork for the generation of biotic resistance, leading to an increase in antibiotic tolerance by many microorganisms. Lastly, considerations must be made regarding reports of eco-toxicity: while increasing the length of the alkyl chain enhances the antimicrobial efficacy of...

presence of alkyl groups in the benzene ring of the phenol due to increased steric hindrance [117]. In general, the classes of molecules demonstrate effectiveness in inhibiting growth in the following order: phenols, cinnamic aldehydes, alcohols, aldehydes, ketones, ethers, and finally hydrocarbons ...
In the human body, certain amino acids can be converted to other amino acids, proteins, glucose, fatty acids or ketones [42,43]. Other functions of amino acids: Chemical messengers (neurotransmitters) in the nervous system: aspartate, GABA, glutamate, glycine, serine Precursors of other neurot...
Fig. 4. 3-Thia fatty acids affect pathways of hepatic BCAA catabolism and 3-HIB degradation. (A) Levels of various short chain acyl-CoA derivatives in liver homogenates of rats treated with TTA (n = 5) or BCMTD (n = 5) for 7 days. The results are presented as mean ± S.D. (On...
We evaluated the quality and content of fish oil supplements in New Zealand. All encapsulated fish oil supplements marketed in New Zealand were eligible for inclusion. Fatty acid content was measured by gas chromatography. Peroxide values (PV) and anisid
A majority of the DUBs inhibitors are compounds with Michael acceptors such as α, β-unsaturated ketones which are capable of forming covalent adducts with free thiols of nucleophilic cysteine which in turn blocks the DUBs activity [178]. A diverse number of compounds ranging from synthetic small...
