<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>Selenocystine, a broad-spectrum anticancer agent, effectively induces DNA damage, notably DNA double-strand breaks (DSBs), in HepG2 cells, showcasing</p>

<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>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>

<p>13-OAHSA, a branched fatty acid ester of hydroxy fatty acids (FAHFAs), results from the esterification of oleic acid to 13-hydroxy stearic acid. It represents a significant component of the FAHFA family, most abundantly expressed in the serum of glucose-tolerant AG4OX mice that exhibit adipose tissue-specific overexpression of the Glut4 glucose transporter. 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>15-deoxy-Δ12,14-Prostaglandin D2 (15-deoxy-Δ12,14-PGD2) is a PGD2 metabolite functioning as an agonist for the PGD2 receptor 2 (DP2), with a binding affinity (Ki) of 50 nM for the mouse DP2 receptor expressed in HEK293 cell membranes. It activates eosinophils with an EC50 of 8 nM and enhances the recruitment of steroid receptor coactivator-1 (SRC-1) to peroxisome proliferator-activated receptor γ (PPARγ), initiating PPARγ-mediated transcription at 5 µM concentration.

<p>Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are recent discoveries in endogenous lipids that are influenced by dietary changes such as fasting and high-fat diets, showing a link with enhanced insulin sensitivity in mice. These compounds typically feature a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) bound to a hydroxy group on another C-16 or C-18 fatty chain. A specific FAHFA, 9-POHSA, consists of palmitoleic acid connected at the hydroxy stearic acid's 9th position. This molecule, in particular, exhibits notably increased levels in the serum of glucose-tolerant AG4OX mice, which express the Glut4 glucose transporter predominantly in their adipose tissue. Given the broader family of FAHFAs' roles in enhancing glucose tolerance, promoting insulin secretion, and exerting anti-inflammatory effects, 9-POHSA emerges as a potential bioactive lipid involved in managing metabolic syndrome and inflammation.</p>
