<p>N-Acyl taurines, such as N-lignoceroyl taurine, alongside various arachidonoyl amino acid conjugates like N-arachidonoyl dopamine and N-arachidonoyl-L-serine, have been identified in bovine brain and through mass spectrometry lipidomic studies in the brain and spinal cord of both wild-type and FAAH knockout mice. Notably, N-lignoceroyl taurine levels were found to be 23-26 times higher in FAAH knockout mice than in wild types, suggesting its degradation by FAAH, despite in vitro evidence showing FAAH hydrolyzes N-lignoceroyl taurine significantly slower than oleoyl ethanolamide. Additionally, N-acyl taurines with polyunsaturated acyl chains are known to activate TRPV1 and TRPV4 channels within the transient receptor potential (TRP) family of calcium channels.</p>

<p>Leukotriene C4 (14,15-LTC4) is an inflammatory mediator synthesized from arachidonic acid through the actions of 15- and 12-lipoxygenases (LOs), involving intermediates such as 15-HpETE and 14,15-LTA4. Unlike the majority of leukotrienes formed via the 5-LO pathway, 14,15-LTC4 is an eoxin predominantly produced by eosinophils, although mast cells and nasal polyps can also synthesize it. While its physiological roles are not well understood, 14,15-LTC4 exhibits limited contractile activity on guinea pig ileum and pulmonary parenchyma. However, it can increase vascular permeability in human endothelial cell monolayers in vitro with potency comparable to 5-LO-derived leukotrienes, contributing to plasma leakage characteristic of inflammation.</p>

Similar to other FAHFAs which are known to enhance glucose tolerance, stimulate insulin secretion, and exert anti-inflammatory effects, 13-OAHSA may play a pivotal role in managing metabolic syndrome and inflammation.</p>

<p>N-Oleoyl taurine, an amino-acyl endocannabinoid isolated from rat brain, along with several arachidonoyl amino acids such as N-arachidonoyl dopamine and N-arachidonoyl serine, have been derived from bovine brain. Mass spectral lipidomics analysis of rat brain revealed a series of fatty acyl amides of taurine, marking the discovery of a new class of compounds. These compounds, found in the kidney, are known to activate members of the transient receptor potential (TRP) family of calcium channels, with N-Oleoyl taurine specifically potentially activating TRPV1 and TRPV4 channels.</p>

Moreover, as a TP receptor agonist, PGH2 irreversibly aggregates human platelets at concentrations of 50-100 ng/ml.</p>

<p>11β-13,14-Dihydro-15-keto PGF2α, a PGD2 metabolite in the 15-hydroxy PGDH pathway, is formed in human males upon infusion or inhalation of tritiated PGD2, with peak plasma levels of both 11β-PGF2α and 11β-13,14-dihydro-15-keto PGF2α observed within 10 minutes. In human lung homogenates, PGD2 is metabolized firstly to 11β-PGF2α and subsequently to 11β-15-keto-PGF2α in the presence of NAD+, but not to 11β-13,14-dihydro-15-keto PGF2α. Conversely, guinea pig liver and kidney homogenates can metabolize PGD2 to 11β-13,14-dihydro-15-keto PGF2α via 11β-PGF2α, with both NAD+ and NADP+ being requisite for this conversion.</p>

<p>Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are lipids recently discovered to be modulated by dietary influences such as fasting and high-fat feeding, and they play a role in enhancing insulin sensitivity. These compounds typically feature a carbon-16 or carbon-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) esterified to a carbon-16 or carbon-18 hydroxy fatty acid. A specific example is 12-SAHSA, which consists of stearic acid linked to 12-hydroxy stearic acid. Notably, 12-SAHSA levels are found to be moderately increased in the serum of glucose tolerant AG4OX mice, a model characterized by adipose tissue-specific overexpression of the Glut4 glucose transporter.</p>

<p>Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are recently discovered lipids that play a role in the body's response to fasting and high-fat diets, with a link to insulin sensitivity. These compounds consist of a long-chain fatty acid (such as palmitoleic, palmitic, oleic, or stearic acid) bonded to a hydroxy fatty acid, both ranging in length from C-16 to C-18. Specifically, 12-OAHSA is a type of FAHFA where oleic acid is attached to the 12th carbon of hydroxy stearic acid. Within the FAHFA family, OAHSAs are particularly notable for their high concentration in the serum of AG4OX mice, a strain engineered to express the Glut4 glucose transporter predominantly in their adipose tissue, which demonstrates an enhanced glucose tolerance.</p>

<p>10-OAHSA is a newly discovered endogenous lipid categorized within the group of branched fatty acid esters of hydroxy fatty acids (FAHFAs). This specific FAHFA comprises oleic acid esterified to 10-hydroxy stearic acid. It stands out among its FAHFA counterparts for its potential bioactive properties, similar to other members of its family such as PAHSAs, which are notably prevalent in the adipose tissue of AG4OX mice exhibiting glucose tolerance due to overexpression of the Glut4 glucose transporter specifically in adipose tissue. Like other FAHFAs, 10-OAHSA may play significant roles in enhancing glucose tolerance, stimulating insulin secretion, and exerting anti-inflammatory effects, which suggests its importance in managing metabolic syndrome and inflammation.</p>

<p>Very long chain polyunsaturated fatty acids (VLCPUFA), notably present in the retina, sperm, and brain, have yet to be fully understood in terms of their biosynthesis and functional roles within these tissues.

<p>Branched fatty acid esters of hydroxy fatty acids (FAHFAs) have emerged as significant regulators of metabolic processes, influenced by dietary changes such as fasting and high-fat diets, and are linked to improved insulin sensitivity in mice. These compounds typically feature a fatty acid chain, either C-16 or C-18 in length (for example, palmitoleic, palmitic, oleic, or stearic acid), esterified to a hydroxy fatty acid of similar length. A specific FAHFA, 12-POHSA, involves the esterification of palmitoleic acid to the 12th carbon of stearic acid. Notably, 12-POHSA levels are markedly higher in the serum of AG4OX mice, which exhibit enhanced glucose tolerance due to overexpression of the Glut4 glucose transporter in adipose tissue. Given the capacity of FAHFAs to enhance glucose tolerance, stimulate insulin secretion, and exert anti-inflammatory actions, 12-POHSA holds potential as a bioactive lipid implicated in managing metabolic syndrome and inflammation.</p>

<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>
