Cov tshuaj tiv thaiv formaldehyde yog ib qho tshuaj tiv thaiv prebiotic uas paub zoo tshaj plaws rau kev tsim cov suab thaj. Hauv txoj haujlwm no, peb qhia tau tias cov txheej txheem Cannizzaro yog cov txheej txheem tseem ceeb rau cov tshuaj tiv thaiv toluose nyob rau hauv ntau yam xwm txheej sib txawv thiab yog li ntawd xav tau cov tshuaj catalysts rau cov tshuaj tiv thaiv toluose nyob rau hauv ntau yam xwm txheej ib puag ncig.
Cov tshuaj formaldehyde uas tau kawm no feem ntau tsim cov organic acids uas cuam tshuam nrog kev ua haujlwm ntawm lub cev (protometabolic system) thiab me ntsis ntawm cov suab thaj seem. Qhov no yog vim muaj kev lwj ntawm ntau cov suab thaj uas tsim los ntawm cov tshuaj methyl sugar thiab kev tsim ntau cov acids los ntawm cov tshuaj Cannizzaro.
Peb kuj qhia txog kev sib txawv ntawm Lewis acid catalysis ntawm toluose reactions los ntawm cov mineral systems uas cuam tshuam nrog serpentinization. Cov minerals uas ua rau muaj kev ua haujlwm catalytic suav nrog olivine, serpentine, calcium thiab magnesium minerals suav nrog dolomite, calcite thiab peb lub vaj tshuaj calcium thiab magnesium. Tsis tas li ntawd, kev tshawb fawb txog theem thawj zaug ntawm formaldehyde reaction tau ua tiav los kawm txog kev sib xyaw ntawm formaldehyde los tsim methanol thiab formic acid lossis los tsim glycolaldehyde los ntawm Cannizzaro reaction.
Yog li ntawd, peb xav tias serpentinization yog ib qho txheej txheem pib uas yuav tsum tau rau kev pib ntawm ib qho yooj yim protometabolic system (formometabolic system).
