part of monocarboxylic acid transmembrane transporter activity lactate transmembrane transporter activity https://github.com/geneontology/go-ontology/issues/24076 https://github.com/geneontology/go-ontology/issues/27521 Enables the transfer of lactate from one side of a membrane to the other. Lactate is 2-hydroxypropanoate, CH3-CHOH-COOH; L(+)-lactate is formed by anaerobic glycolysis in animal tissues, and DL-lactate is found in sour milk, molasses and certain fruit juices. molecular_function monocarboxylate (lactate, pyruvate, mevalonate) uptake/efflux porter activity Reactome:R-HSA-373875 Reactome:R-HSA-373867 GO:0015129 lactate transmembrane transport
