Formate is a common C-1 source in living systems. It is formed from many precursors including choline, serine, and sarcosine. It provides a C-1 source in the biosynthesis of some nucleic acids. Formate (or formic acid) is ina leaving group in the demethylation of some sterols.. These conversions are catalyzed by … Meer weergeven Formate (IUPAC name: methanoate) is the conjugate base of formic acid. Formate is an anion (HCO−2) or its derivatives such as ester of formic acid. The salts and esters are generally colorless. Meer weergeven Formate esters have the formula HCOOR (alternative way of writing formula ROC(O)H or RO2CH). Many form spontaneously when alcohols dissolve in formic acid. Meer weergeven • ethyl formate, CH3CH2(HCOO) • sodium formate, Na(HCOO) • potassium formate, K(HCOO) Meer weergeven When dissolved in water, formic acid converts to formate: HCO2H → HCO−2 + H Formate is a planar anion. The two oxygen atoms are equivalent and bear a partial negative charge. The remaining C-H bond is not acidic. Meer weergeven Formate salts have the formula M(O2CH)(H2O)x.
