Cov khoom siv
4-Methoxybenzoic acid tau siv rau hauv oxidation thiab txo cov cytochrome c hauv kev daws los ntawm kev sib txawv ntawm tus kheej sib dhos monolayers ntawm kub electrodes siv cyclic voltammetry. Nws tseem yog ib qho ntawm cov pa roj carbon thiab lub zog rau kev loj hlob hauv kab lis kev cai ntawm Nocardia sp. DSM 1069. Nqe lus piav qhia Anisic acid los yog methoxybenzoic acid yog cov organic compound uas yog carboxylic acid. P-Anisic acid, hu ua 4-methoxybenzoic acid los yog Draconic acid, uas yog ib tug methoxybenzoic acid hloov nrog ib tug methoxy pab pawg neeg ntawm txoj hauj lwm C-4, thiab P-Anisic acid yog cov organic acid nrog qab zib tsw. Nws yog ib qho ntawm cov isomers (m-anisic acid, thiab o-anisic acid) ntawm anisic acid. Lub sij hawm anisic acid feem ntau siv los piav txog p-anisic acid thiab P-anisic acid yog tsim los ntawm oxidation ntawm p-cresyl-methyl ether. P-Anisic acid yog carboxylic acid pom nyob rau hauv anise, flowering nroj tsuag nyob rau hauv tsev neeg Apiaceae. P-Anisic acid muaj nyob rau hauv cov dawb crystalline khoom uas yog insoluble nyob rau hauv dej, heev soluble nyob rau hauv cawv, thiab soluble nyob rau hauv ether.
