Phenoxymethylpenicillin functional groups

WebPenicillin V contains electronegative oxygen in the PhO substituent, which draws the electron density away from the amide carbonyl group and so reduces its tendency to act as a nucleophile and react with the β-lactam ring. This has important consequences. Web16. mar 2016 · The functional groups are: at 1, a thioether at 4,7,8, an amide at 11,12,13, a carboxylate ion at 14,15, an amide

WebAs they contain a number of keto groups in the molecules they are also considered a class of compounds known as polyketides. Members belonging to this antibiotic class include tetracycline, oxytetracycline, chlortetracycline, demeclocycline, minocycline, doxycycline, methacycline and lymecycline. WebPenicillin acts by inhibiting the transpeptidase enzyme - it mimics a peptidoglycan chain and an ester is formed that joins the penicillin to the enzyme. As the penicillin group is so large, it prevents attack of a nucleophile at the ester carbonyl and so the ester does not react with the second peptidoglycan chain. snow nyc weather https://thecykle.com
