Monocarboxylate (Lactate) transporter

Monocarboxylate transporters, or MCTs, constitute a family of proton-linked plasma membrane transporters that carry molecules having one carboxylate group (monocarboxylates), such as lactate and pyruvate.

Chemical equation

$Lactate_{in} \rightleftharpoons Lactate_{out}$

Rate equation

Reversible Michaelis-Menten rate law is used

$\frac{V_{f}\frac{[Lactate_{in}]}{Km_{Lactate_{in}}}- V_{r}\frac{[Lactate_{out}]}{Km_{Lactate_{out}}}}{1+ \frac{[Lactate_{in}]}{Km_{Lactate_{in}}} - \frac{[Lactate_{out}]}{Km_{Lactate_{out}}} }$
