PEP is a 3C compound which serves as primary$C{O}_2$acceptor in the mesophyll cell cytoplasm of$C_4$plants like Maize, Sugarcane,Sorghumetc.

PEP is able to rapidly fix carbon at very low concentrations of hydrogen carbonate in presence of Phosphoenolpyruvate carboxylase enzyme the addition of bicarbonate$\left(HC{O}_3^{-}\right)$to phosphoenolpyruvate$\left(PEP\right)$to form the four-carbon compound oxaloacetate and inorganic phosphate

$PEP+HC{O}_3^{-}\to oxaloacetate+Pi$
