β-Lactose is a disaccharide commonly found in milk and dairy products. It consists of two monosaccharides, glucose and galactose, linked by β-glycosidic bonds. β-Lactose has various applications in the food industry, especially as a sweetener and bulking agent. Furthermore, it can be used as a substrate for enzymes involved in lactose metabolism and as a model compound for studying carbohydrate-protein interactions.

(2R,3R)-Butane-2,3-diol is a non-covalent, reversible agonist targeting lanthanum (La 3+)-sensitive calcium channels in bacteria (e.g., Escherichia coli) with an EC50 of approximately 25 mM. (2R,3R)-Butane-2,3-diol binds to calcium channel proteins or related complexes, induces channel opening, promotes extracellular calcium influx, and triggers intracellular calcium transients, which may regulate bacterial physiological activities such as growth, metabolism, and signal transduction. (2R,3R)-Butane-2,3-diol mediates bacterial-host cell signaling interactions and affects the metabolic balance of intestinal microorganisms, and can be used to study lactose intolerance and other related diseases .

Metabolic Disease

Beta-galactose dehydrogenase is a selective catalyst for β-galactose. Under pH 8.6 conditions, beta-galactose dehydrogenase catalyzes the oxidation of β-galactose, produced by the hydrolysis of lactose by β-galactosidase, with nicotinamide adenine dinucleotide (NAD) to produce reduced nicotinamide adenine dinucleotide (NADH). Beta-galactose dehydrogenase specifically mediates this oxidation reaction for the quantitative detection of the substrate, used in the analysis of lactose concentration in samples such as breast milk .

Soy PE (LPI) is the most abundant phospholipid in prokaryotes and the second most abundant found in the membrane of mammalian, plant, and yeast cells, comprising approximately 25% of total mammalian phospholipids. In the brain, phosphatidylethanolamine comprises almost half of the total phospholipids. It is synthesized mainly through the cytidine diphosphate-ethanolamine and phosphatidylserine decarboxylation pathways, which occur in the endoplasmic reticulum (ER) and mitochondrial membranes, respectively. It is a precursor in the synthesis of phosphatidylcholine and arachidonoyl ethanolamide and is a source of ethanolamine used in various cellular functions. In E.coli, phosphatidylethanolamine deficiency prevents proper assembly of lactose permease, suggesting a role as a lipid chaperone. It is a cofactor in the propagation of prions in vitro and can convert recombinant mammalian proteins into infectious molecules even in the absence of RNA. This product contains phosphatidylethanolamine molecular species with variable fatty acyl chain lengths at the sn-1 and sn-2 positions .
