DL-O-Phosphoserine	Microorganisms Classification of Application Fields Ketones, Aldehydes, Acids Metabolic Disease Endogenous metabolite Disease Research Fields Source Classification	Endogenous Metabolite
DL-O-Phosphoserine is a normal metabolite in human biofluids and is a mixture of phosphoserine with two stereochemical structures (D-type and L-type O-phospho-serine). O-phospho-L-serine is a competitive inhibitor of serine racemase and phagocytosis. O-phospho-L-serine inhibits the enzymatic reaction by competing with the active site of serine racemase, thereby affecting the production of D-serine. O-phospho-L-serine also mimics the phosphatidylserine head group, binds to the phosphatidylserine receptor, interferes with phagocytic signal transduction, and partially blocks the phagocytosis of apoptotic cells by cells. O-phospho-L-serin can be used in the research of retinal regeneration, bone repair, and insect growth and development .

Cucumarioside H	Triterpenes Animals Terpenoids Source Classification	Mitochondrial Metabolism
Cucumarioside H is a novel triterpene glycoside isolated from the Far Eastern sea cucumber Eupentacta fraudatrix, including H2, H3 and H4. These glycosides have a branched pentasyl structure with a rare 3-O-methyl-D-xylose as the terminal monosaccharide. H2 contains 23,24,25,26,27-pentanolone sterols and has an 18(16)-lactone, which is not common in sea cucumbers. The glycoside portion of H3 contains an extremely rare ethoxyl radical at the 25 position, which may be an artifact formed during the long ethanol extraction process. Studies have shown that H1-3 are cytotoxic to mouse spleen lymphocytes, hemolytic to mouse erythrocytes, and cytotoxic to Ehrlich carcinoma cells. The presence of a 25-hydroxyl group in the glycoside portion significantly reduces these activities.
