O le a le glyoxylic acid?

Glyoxylic acid, e lauiloa foi o le acid formoic, hydrated glyoxylic acid ma le oxyacetic acid, chemical formula C2H203, o le aldehyde acid sili ona faigofie, lea o loʻo i ai i fualaau aina e le o matua, lau lanu meamata vaivai ma suka beets. O tioata mai vai o tioata monoclinic (e iai le 1/2 vai tioata). Ole mamafa ole mole mole ole 70.04. O le mea e liusuavai ai e 98 ℃. E i ai se tofo le lelei. Ose acid corrosive malosi, lea e faigofie ona deliquescence ma e mafai ona fausia se paʻu pe a faʻaalia i le ea. E solu teisi i le ethanol, eter ma benzene, ma e mafai ona solufua saoloto i le vai. Ole vai vai e mautu ma e le fa'aleagaina ile ea. O lo'o iai ile vai vaifofo ile fa'asusu. E mafai ona tali atu i le tele o u'amea se'i vagana ua u'amea. O lo'o i ai uiga o le acid ma le aldehyde.
