I-formaldehyde reaction yi-prebiotic chemical reaction enokwenzeka eyaziwa kakhulu ngokuvelisa iiswekile. Kulo msebenzi, sibonisa ukuba inkqubo yeCannizzaro yinkqubo elawulayo ye-toluose reactions phantsi kweemeko ezahlukeneyo kwaye ngoko ke ifuna ii-catalysts ze-toluose reactions phantsi kweemeko ezahlukeneyo zendalo.
I-formaldehyde reaction efundwayo ivelisa ikakhulu ii-organic acids ezinxulumene ne-metabolism (inkqubo ye-protometabolic) kunye nenani elincinci leswekile eseleyo. Oku kungenxa yokubola kweeswekile ezininzi eziveliswa yi-methyl sugar reaction kunye nokwakheka kwee-acids ezininzi yi-Cannizzaro reaction.
Sikwabonisa ukwahlukana kwe-Lewis acid catalysis yeempendulo ze-toluose ziinkqubo zeeminerali ezinxulumene ne-serpentine. Iiminerali ezibonisa umsebenzi we-catalytic ziquka i-olivine, i-serpentine, i-calcium kunye ne-magnesium minerals kuquka i-dolomite, i-calcite kunye negadi yethu yeekhemikhali ze-calcium kunye ne-magnesium. Ukongeza, izifundo zokubala zesigaba sokuqala se-formaldehyde reaction zenziwe ukuze kufundwe i-reaction ye-formaldehyde ukuze kwenziwe i-methanol kunye ne-formic acid okanye ukwenza i-glycolaldehyde nge-reaction ye-Cannizzaro.
Ngoko ke sicebisa ukuba i-serpentinization yinkqubo yokuqalisa efunekayo ekuqaliseni inkqubo elula ye-protometabolic (inkqubo ye-formometabolic).
