I-I-I-Protocatechuic acid CAS 99-50-3Isicelo

I-Protocatechuic acid (PCA) yi-3,4-dihydroxybenzoic acid. I-phenolic acid elula, eyisandulela sokuhlanganiswa kwamanye ama-molecule ayinkimbinkimbi, njenge-anthocyanin 3-ochemicalbook- β- D-glucoside ne-vanillin. Itholakala emifino edliwayo, izithelo, amantongomane, irayisi elinsundu, ama-pecans, itiye, izimbali ze-hibiscus kanye neminye imithi yamakhambi yaseShayina.
