Lactic acid (Standard) is the analytical standard of Lactic acid (HY-B2227). Intended for research and analytical applications, it acts as a hydroxycarboxylic acid receptor 1 (HCAR1) activator and an epigenetic modulator inducing lysine residues lactylation. This compound is also a glycolysis end-product, bridging the gap between glycolysis and oxidative phosphorylation.
- Acts as an oncometabolite.
- Possesses an immune protective role in anti-tumor immunity.
- Exhibits antimicrobial activity, suitable for food preservation.
- Used as an analytical standard in qualitative, quantitative, and methodological research experiments.
- Applicable in techniques such as HPLC, GC, and MS.

Lactic Dehydrogenase (LDH) has a total molecular weight of 140 kDa and is composed of 4 subunits which are designated M subunit (muscle) and H subunit (heart). These subunits may be mixed in any of 5 combinations (M4 M3H1 M2H2 MH3 and H4). Skeletal muscle contains LDH that is predominately M4 with some small amounts of M3H and traces of H2H2. The H and M subunits are quite similar in molecular weight but differ substantially in amino acid composition. Rabbit muscle LDH dissociates into dimeric species (MW ~70 kDa) in acetate-chloride at pH 5.0 the dissociation is reversible. Biochemistry 13 3527-3531 (1974). Oxidizes glyoxylate and lactate.Isoelectric point 8.4-8.6Optimal pH 7.5 .

Histone lysine lactation (Kla) is a newly discovered histone modification that regulates gene expression in macrophages. In M1 macrophages, lactic acid is derived from incompletely oxidized glucose and then produces lactyl-CoA, which is transferred via acetyltransferase p300 to the lysine tail of the histone. This modification is abundant in gene promoter regions that lack acetylation and are associated with gene expression activation.
