Liu says damage caused by two key inhibitors, furfural (short for 2-furaldehyde
) and HMF (which stands for 5-hydroxymethyl-2-furaldehyde), is representative of the havoc that inhibitors can wreak on biorefinery yeasts.

These workers also reported the oxidative behaviours and relative reactivities ofsome aliphatic aldehydes, XCHO (where X = H-, Me-, Me[CH.sub.2], [Me.sub.2]CH-), 2-furaldehyde
and aromatic aldehydes, [YC.sub.6][H.sub.4]CHO (where Y = -H, -[NO.sub.2] -Cl and OMe) towards bis (dihydrogen tellurato)cuprate(III) ion22 in alkaline medium.

Of interest, under acidic conditions, are the pentoses, which decompose and dehydrate to form 2-furaldehyde
and the hexoses, which decompose and dehydrate to form 5-(hydroxy-methyl)-2-furaldehyde.
