(s)baminoisobutyric acid

(S)-3-Hydroxybutanoic acid (L-(+)-3-Hydroxybutyric acid) is a normal human metabolite that has been found elevated in geriatric patients remitting from depression. (S)-3-Hydroxybutanoic acid is synthesized in the liver from acetyl-CoA in humans, and can be used as an energy source by the brain when blood glucose is low.

(S)-Coriolic acid (13(S)-HODE) is an important intracellular signaling agent, generated by the reaction of linoleic acid with plant and mammalian lipoxygenases, and is involved in cell proliferation and differentiation in various biological systems. (S)-Coriolic acid inhibits the adhesion of tumor cells to the vascular endothelium and down-regulates the expression of IRGpIIb/IIIa receptors at around 1 μM. (S)-Coriolic acid is a metabolite of 15-lipoxygenase (15-LOX), which often acts as an endogenous ligand to activate PPARγ. (S)-Coriolic acid induces mitochondrial dysfunction and airway epithelial damage.

Ganodermic acid S, as a membrane acting agent isolated from the fungus Ganoderma lucidum, exerts multiple effects on human platelet function.

S-30-Hydroxygambogic acid, a polyprenylated xanthone epimer isolated from the gamboges of Garcinia hanburyi, exhibits cytotoxicity against Human Leukemia K562 cell lines with IC50 values of 4.49 μM for K562/R and 3.61 μM for K562/S. This compound is utilized in cancer research [1].

(S)-2-acetamido-4-amino-4-oxobutanoic acid (Nα-Acetyl-L-asparagine), also known as acasn, is an endogenous metabolite.

A novel combination of triterpenoids includes at least ganoderic acid S (GAS), ganoderic acid T (GAT), ganoderic acid Me (GAMe), ganoderic acid R (GAR), and ganodermic acid S (GMAS), the composition is suitable for the treatment or prophylaxis of colon ca

(S)-b-aminoisobutyric acid is a non-protein amino acid originating from the catabolism of valine and thymine.

(S)-2-Hydroxybutanoic acid is a natural product for research related to life sciences. The catalog number is T65934 and the CAS number is 3347-90-8.

(S)-3-(4-Hydroxyphenyl)-2-hydroxypropionic acid, a metabolite isolated from Cryptococcus mesentericus cultures, exhibits high DPPH radical scavenging activity and antioxidant activity.

(S)-Gossypol acetic acid is the isomer of a natural product Gossypol.

(S)-2-Amino-3-(4-hydroxy-3,5-diiodophenyl)propanoic acid dihydrate (jodgorgon) is a product from the iodination of MONOIODOTYROSINE. In the biosynthesis of thyroid hormones, diiodotyrosine residues are coupled with other monoiodotyrosine or diiodotyrosine residues to form T4 or T3 thyroid hormones.

(S)-Malic acid ((S)-2-Hydroxysuccinic acid) is a tart-tasting organic dicarboxylic acid that plays a role in many sour or tart foods. Apples contain malic acid, which contributes to the sourness of a green apple. Malic acid can make a wine taste tart, although the amount decreases with increasing fruit ripeness. (wikipedia). In its ionized form malic acid is called malate. Malate is an intermediate of the TCA cycle along with fumarate. It can also be formed from pyruvate as one of the anaplerotic reactions. In humans, malic acid is both derived from food sources and synthesized in the body through the citric acid cycle or Krebs cycle which takes place in the mitochondria. Malate's importance to the production of energy in the body during both aerobic and anaerobic conditions is well established. Under aerobic conditions, the oxidation of malate to oxaloacetate provides reducing equivalents to the mitochondria through the malate-aspartate redox shuttle. During anaerobic conditions, where a buildup of excess of reducing equivalents inhibits glycolysis, malic acid's simultaneous reduction to succinate and oxidation to oxaloacetate is capable of removing the accumulating reducing equivalents. This allows malic acid to reverse hypoxia's inhibition of glycolysis and energy production. In studies on rats it has been found that only tissue malate is depleted following exhaustive physical activity. Other key metabolites from the citric acid cycle needed for energy production were found to be unchanged. Because of this, a deficiency of malic acid has been hypothesized to be a major cause of physical exhaustion. Notably, the administration of malic acid to rats has been shown to elevate mitochondrial malate and increase mitochondrial respiration and energy production.

(S)-Leucic acid is an amino acid metabolite used as a muscle builder.

Dexamethasone exhibits anti-inflammatory activity.

(S)-3,4-Dihydroxybutyric acid is a human urinary metabolite.

(S)-2-Hydroxy-3-phenylpropanoic acid (L-(−)-3-Phenyllactic acid) is a chiral aromatic compound involved in phenylalanine metabolism. It is likely produced from phenylpyruvate via the action of lactate dehydrogenase. The D-form of this organic acid is typically derived from bacterial sources while the L-form is almost certainly endogenous. Levels of phenyllactate are normally very low in blood or urine. High levels of PLA in the urine or blood are often indicative of phenylketonuria (PKU) and hyperphenylalaninemia (HPA). PKU is due to lack of the enzyme phenylalanine hydroxylase (PAH) so that phenylalanine is converted not to tyrosine but to phenylpyruvic acid (a precursor of phenylacetate).
