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..

Formate is an anion (HCO−2) or its derivatives such as ester of formic acid. The salts and esters are generally colorless. See more 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. The most important formate ester is methyl formate, … See more • ethyl formate, CH3CH2(HCOO) • sodium formate, Na(HCOO) • potassium formate, K(HCOO) See more 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. See more Formate salts have the formula M(O2CH)(H2O)x. Such salts are prone to decarboxylation. For example, hydrated nickel formate decarboxylates at about 200 °C with reduction of … See more
