Isicelo

D - (-) - I-Arabinose yiswekile yokunciphisa eyi-analogue ye-pentose ye-D-ribose. Iyingxenye ye-arabinogalactan kwindonga yeseli ye-Bacillus subtilis kwaye isebenza njenge-substrate ye-synthesis ye-D-erythroid ascorbic acid kwimvubelo; D - (-) - iArabinose isetyenziselwa ukukhusela ukungcoliseka kwentsimbi enzima
