Isingeniso

Okubabayo kancane. Kulula ukumunca umswakama futhi uzinzile ngaphansi kwezimo ezijwayelekile, kodwa kulula ukukhiqiza i-propionaldehyde, i-lactic acid, i-pyruvate ne-acetic acid emazingeni okushisa aphezulu. Ixubene namanzi, i-acetone ne-chloroform, futhi inyibilika ku-ether. Umthamo obulalayo omaphakathi (igundane, ngomlomo) ngu-25ml/kg.
