<p>NAAD sodium salt (NAAD Na salt) is a substrate of nicotinamide adenine dinucleotide synthase and can be used in studies about the specificity and kinetics of</p>

<p>Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are endogenous lipids that are influenced by fasting and high-fat diets and linked to improved insulin sensitivity in mice. These compounds typically feature a chain of either 16 or 18 carbon atoms (for example, palmitoleic, palmitic, oleic, or stearic acid) esterified with a hydroxy fatty acid chain of similar length. One specific FAHFA, known as 5-OAHSA, consists of oleic acid bonded to the fifth carbon of hydroxy stearic acid. Within the FAHFA family, OAHSAs exhibit the highest serum levels in AG4OX mice, which are known for their glucose tolerance attributed to the overexpression of the Glut4 glucose transporter in adipose tissue.</p>

<p>Hypusine is an N-terminal amino alcohol derivative of Lys occurring in bovine brain &amp;</p>

<p>Argininosuccinic acid disodium, involved in the urea cycle's fourth step, is cleaved by argininosuccinate lyase (ASL) into arginine and fumarate.</p>

<p>5α-Androst-16-en-3-one, a mammalian pheromone present in boar saliva, plays a crucial role in facilitating social and sexual interactions by acting as a volatile chemical cue. It is utilized to prime sows in estrus for mating or artificial insemination, underscoring its significance in reproductive behavior. Additionally, this compound is detected in human sweat and urine, where it is involved in studies concerning receptor-mediated odorant detection and the genetic foundations of anosmias, thereby broadening its scope of relevance beyond the animal kingdom.</p>

<p>Sulforhodamine 101 DHPE, a fluorescent probe, results from the conjugation of sulforhodamine 101, a red fluorescent dye with excitation/emission spectra of 586/605 nm, to the phospholipid 1,2-dipalmitoyl-sn-glycero-3-PE. It effectively integrates into phospholipid bilayers and is utilized for imaging solid supported lipid bilayers, detecting protein-ligand interactions on bilayers, and monitoring lipid probe colocalization in liposomes through resonance energy transfer (RET).</p>

<p>1,2-Dioleoyl-3-docosohexaenoyl-rac-glycerol, a triacylglycerol, consists of oleic acid at the sn-1 and sn-2 positions and docosahexaenoic acid at the sn-3 position. This compound has been identified in human breast milk.</p>

<p>Taurohyocholic acid (THCA), a taurine-conjugated form of porcine-specific primary bile acid hyocholic acid, inhibits cholesterol crystal precipitation by stabilizing cholesterol in the liquid-crystalline phase and prevents cholestasis and cellular necrosis in isolated rat livers induced by taurolithocholic acid. Additionally, THCA levels rise in the urine of patients with hepatitis B-induced cirrhosis.</p>

<p>7,12-Diketolithocholic acid, a bile acid, exhibits elevated plasma levels in patients experiencing cholestasis.</p>

<p>1-Linoleoyl-3-α-linolenoyl-rac-glycerol, a diacylglycerol, features linoleic acid at the sn-1 position and α-linolenic acid at the sn-3 position. This compound is identified in olive oil that has undergone lipase-catalyzed glycerolysis, utilizing immobilized lipase B derived from C. antarctica.</p>

<p>Biliverdin, produced through the oxidation of bilirubin, can also be synthesized through a non-protoporphyrin pathway in Corynebacterium glutamicum [1].</p>

<p>2-Myristyl dipalmitin (PMP), a triglyceride of palmitic acid, shows potential as a lipid marker for Wilson's disease (WD) [1] [2].</p>

VPC32183 is a competitive antagonist of LPA1 and LPA3 receptors.

<p>Prostaglandin E1 (PGE1), though not predominantly found in nature, plays a significant role in clinical treatments, addressing conditions such as peripheral occlusive vascular disease, erectile dysfunction, and neonatal cardiology issues. The metabolism of PGE1 primarily begins with the oxidation at C-15, producing 13,14-dihydro-15-keto PGE1 as its major metabolite. Alternatively, inhibiting this pathway or overwhelming it with too much PGE1 could potentially enhance the production of 2,3-dinor metabolites, like 2,3-dinor PGE1, though their biological activities remain unreported. Cayman Chemical stands out as a prominent provider of prostaglandins and their metabolites, uniquely manufacturing 2,3-dinor PGE1.</p>

<p>Cis-13-Octadecenoic acid, a monounsaturated fatty acid, is identified in bovine milk fat.</p>

<p>C2 Dihydro Ceramide (d18:0/2:0) (C2 Dihydroceramide) is a ceramide that is a precursor of ceramide synthesis and stimulates ABCA1-mediated cholesterol efflux.</p>

<p>(±)16,17-EDT, an oxylipin metabolite of adrenic acid produced through the cytochrome P450 (CYP) pathway, effectively induces dilation in isolated porcine</p>

<p>(+/-)12-HpETE, a vasodilator, is a 12-hydroxyicosatetraenoic acid produced by lipoxygenase [1].</p>

<p>1a,1b-Dihomo Prostaglandin F2α (1a,1b-dihomo PGF2α), a hypothetical product of adrenic acid in the COX pathway, is predominantly synthesized in the renal medulla, reflecting the selective distribution of adrenic acid in this region.</p>

<p>3-Aminoisobutyric acid, a non-protein amino acid resultant from thymine catabolism, plays a significant role in metabolic activities. At a 5 µM concentration, it triggers browning in primary adipocytes, notably elevating uncoupling protein 1 (UCP-1) and CIDEA expression. Additionally, it boosts PPARα expression in both primary adipocytes and mouse inguinal white adipose tissue (WAT) in vivo, alongside enhancing β-oxidation in hepatocytes. Its plasma levels surge post-exercise in mice, and its administration at 100 mg/kg daily curtails weight gain and body fat without diminishing food consumption or hiking energy output, whilst ameliorating glucose tolerance. Notably, 3-aminoisobutyric acid concentrations are heightened in individuals with β-ureidopropionase deficiency, a genetic flaw impairing pyrimidine degradation, affecting plasma, urine, and cerebrospinal fluid.</p>
