Generic Name
Lactic acid
DrugBank Accession Number
DB04398
Background

A normal intermediate in the fermentation (oxidation, metabolism) of sugar. The concentrated form is used internally to prevent gastrointestinal fermentation. (From Stedman, 26th ed) Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste. It is produced by fermentation of a sugar source, such as corn or beets, and then, by neutralizing the resulting lactic acid to create a compound having the formula NaC3H5O3.

Lactic acid was one of active ingredients in Phexxi, a non-hormonal contraceptive agent that was approved by the FDA on May 2020.1

Pharmacodynamics

Lactic acid produces a metabolic alkalinizing effect.

Mechanism of action

Lactate ions are metabolized ultimately to carbon dioxide and water, which requires the consumption of hydrogen cations.

Proton-coupled monocarboxylate symporter. Catalyzes the rapid transport across the plasma membrane of monocarboxylates such as L-lactate, pyruvate and ketone bodies, acetoacetate, beta-hydroxybutyrate and acetate (PubMed:32415067, PubMed:9786900). Dimerization is functionally required and both subunits work cooperatively in transporting substrate (PubMed:32415067)

General Function
Mediates the Na(+)-independent transport of steroid sulfate conjugates and other specific organic anions (PubMed:10873595, PubMed:11159893, PubMed:11932330, PubMed:12724351, PubMed:14610227, PubMed:16908597, PubMed:18501590, PubMed:20507927, PubMed:22201122, PubMed:23531488, PubMed:25132355, PubMed:26383540, PubMed:27576593, PubMed:28408210, PubMed:29871943, PubMed:34628357). Responsible for the transport of estrone 3-sulfate (E1S) through the basal membrane of syncytiotrophoblast, highlighting a potential role in the placental absorption of fetal-derived sulfated steroids including the steroid hormone precursor dehydroepiandrosterone sulfate (DHEA-S) (PubMed:11932330, PubMed:12409283). Also facilitates the uptake of sulfated steroids at the basal/sinusoidal membrane of hepatocytes, therefore accounting for the major part of organic anions clearance of liver (PubMed:11159893). Mediates the intestinal uptake of sulfated steroids (PubMed:12724351, PubMed:28408210). Mediates the uptake of the neurosteroids DHEA-S and pregnenolone sulfate (PregS) into the endothelial cells of the blood-brain barrier as the first step to enter the brain (PubMed:16908597, PubMed:25132355). Also plays a role in the reuptake of neuropeptides such as substance P/TAC1 and vasoactive intestinal peptide/VIP released from retinal neurons (PubMed:25132355). May act as a heme transporter that promotes cellular iron availability via heme oxygenase/HMOX2 and independently of TFRC (PubMed:35714613). Also transports heme by-product coproporphyrin III (CPIII), and may be involved in their hepatic disposition (PubMed:26383540). Mediates the uptake of other substrates such as prostaglandins D2 (PGD2), E1 (PGE1) and E2 (PGE2), taurocholate, L-thyroxine, leukotriene C4 and thromboxane B2 (PubMed:10873595, PubMed:14610227, PubMed:19129463, PubMed:29871943, Ref.25). May contribute to regulate the transport of organic compounds in testis across the blood-testis-barrier (Probable). Shows a pH-sensitive substrate specificity which may be ascribed to the protonation state of the binding site and leads to a stimulation of substrate transport in an acidic microenvironment (PubMed:14610227, PubMed:19129463, PubMed:22201122). The exact transport mechanism has not been yet deciphered but most likely involves an anion exchange, coupling the cellular uptake of organic substrate with the efflux of an anionic compound (PubMed:19129463, PubMed:20507927, PubMed:26277985). Hydrogencarbonate/HCO3(-) acts as a probable counteranion that exchanges for organic anions (PubMed:19129463). Cytoplasmic glutamate may also act as counteranion in the placenta (PubMed:26277985). An inwardly directed proton gradient has also been proposed as the driving force of E1S uptake with a (H(+):E1S) stoichiometry of (1:1) (PubMed:20507927)

General Function
Bidirectional proton-coupled monocarboxylate transporter (PubMed:12946269, PubMed:32946811, PubMed:33333023). Catalyzes the rapid transport across the plasma membrane of many monocarboxylates such as lactate, pyruvate, acetate and the ketone bodies acetoacetate and beta-hydroxybutyrate, and thus contributes to the maintenance of intracellular pH (PubMed:12946269, PubMed:33333023). The transport direction is determined by the proton motive force and the concentration gradient of the substrate monocarboxylate. MCT1 is a major lactate exporter (By similarity). Plays a role in cellular responses to a high-fat diet by modulating the cellular levels of lactate and pyruvate that contribute to the regulation of central metabolic pathways and insulin secretion, with concomitant effects on plasma insulin levels and blood glucose homeostasis (By similarity). Facilitates the protonated monocarboxylate form of succinate export, that its transient protonation upon muscle cell acidification in exercising muscle and ischemic heart (PubMed:32946811). Functions via alternate outward- and inward-open conformation states. Protonation and deprotonation of 309-Asp is essential for the conformational transition (PubMed:33333023)

General Function
Mediates the transport of prostaglandins (PGs, mainly PGE2, PGE1, PGE3, PGF2alpha, PGD2, PGH2) and thromboxanes (thromboxane B2) across the cell membrane (PubMed:11997326, PubMed:26692285, PubMed:8787677). PGs and thromboxanes play fundamental roles in diverse functions such as intraocular pressure, gastric acid secretion, renal salt and water transport, vascular tone, and fever (PubMed:15044627). Plays a role in the clearance of PGs from the circulation through cellular uptake, which allows cytoplasmic oxidation and PG signal termination (PubMed:8787677). PG uptake is dependent upon membrane potential and involves exchange of a monovalent anionic substrate (PGs exist physiologically as an anionic monovalent form) with a stoichiometry of 1:1 for divalent anions or of 1:2 for monovalent anions (PubMed:29204966). Uses lactate, generated by glycolysis, as a counter-substrate to mediate PGE2 influx and efflux (PubMed:11997326). Under nonglycolytic conditions, metabolites other than lactate might serve as counter-substrates (PubMed:11997326). Although the mechanism is not clear, this transporter can function in bidirectional mode (PubMed:29204966). When apically expressed in epithelial cells, it facilitates transcellular transport (also called vectorial release), extracting PG from the apical medium and facilitating transport across the cell toward the basolateral side, whereupon the PG exits the cell by simple diffusion (By similarity). In the renal collecting duct, regulates renal Na+ balance by removing PGE2 from apical medium (PGE2 EP4 receptor is likely localized to the luminal/apical membrane and stimulates Na+ resorption) and transporting it toward the basolateral membrane (where PGE2 EP1 and EP3 receptors inhibit Na+ resorption) (By similarity). Plays a role in endometrium during decidualization, increasing uptake of PGs by decidual cells (PubMed:16339169). Involved in critical events for ovulation (PubMed:27169804). Regulates extracellular PGE2 concentration for follicular development in the ovaries (By similarity). Expressed intracellularly, may contribute to vesicular uptake of newly synthesized intracellular PGs, thereby facilitating exocytotic secretion of PGs without being metabolized (By similarity). Essential core component of the major type of large-conductance anion channel, Maxi-Cl, which plays essential roles in inorganic anion transport, cell volume regulation and release of ATP and glutamate not only in physiological processes but also in pathological processes (By similarity). May contribute to regulate the transport of organic compounds in testis across the blood-testis-barrier (Probable)
