I-Ethyl vallin
I-Ethyl vallin yinxalenye yezinto eziphilayo ngefomula (c2h5o) (HO) C6H3CE. Esi sixhobo esingenamibala siquka i-ring ye-bengdroxyl, i-ethotey, kunye namaqela eFomati kwi-4, 3, kunye ne-1, ngokwahlukeneyo.
I-Ethyl vallin yimolekyuli yokwenziwa, engafumaneki kwindalo. Ilungiselelwe ngokuhamba ngamanyathelo aliqela ukusuka kwi-Cagechol, iqala ngembeko ukuba inike "i-guethol". Le mincili ye-emer nge-glyculoc acid ukuba inike i-acid ye-acid ye-acid ehambelana nayo, eyathi i-oxidation kunye nentsokothi ye-descysid inika i-Ethyl vallin.
Njenge-Exlivonces, i-Ethyl Vallin imalunga namaxesha amathathu njenge-vallin kwaye isetyenziswa kwimveliso yetshokholethi.
