Monocarboxylate transporter

The monocarboxylate transporters, or MCTs, are a family of proton-linked plasma membrane transporters that carry molecules having one carboxylate group (monocarboxylates), such as lactate, pyruvate, and ketones across biological membranes. Acetate is actively transported to intestinal enteroendocrine cells via MCT, termed Targ (short for Tarag in Mongolian).
