1-Hydroxypyrene (1-Pyrenol) 是一种暴露于多环芳烃的生物标志物，存在尿液样本中，也是一种暴露于 pyrenes 中的主要生物标志物。

10(R)-PAHSA is a stereoisomer of 10-PAHSA , an endogenous lipid that belongs to a collection of branched fatty acid esters of hydroxy fatty acids (FAHFAs).

10(S)-PAHSA is a stereoisomer of 10-PAHSA , an endogenous lipid that belongs to a collection of branched fatty acid esters of hydroxy fatty acids (FAHFAs).

10-PAHSA is a newly identified endogenous lipid that belongs to a collection of branched fatty acid esters of hydroxy fatty acids (FAHFAs). It is a FAHFA in which palmitic acid is esterified to 10-hydroxy stearic acid. Among the FAHFA family members, PAHSAs are the most abundant in the adipose tissue of glucose tolerant AG4OX mice, which overexpress the Glut4 glucose transporter specifically in adipose tissue. As other FAHFAs improve glucose tolerance, stimulate insulin secretion, and have anti-inflammatory effects, 10-PAHSA may be a bioactive lipid with roles in metabolic syndrome and inflammation.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are newly identified endogenous lipids regulated by fasting and high-fat feeding and associated with insulin sensitivity. Structurally, these esters are comprised of a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) linked to either a C-16 or C-18 hydroxy substituent. 12-PAHSA is a FAHFA in which palmitic acid is esterified at the 12th carbon of hydroxy stearic acid. Among the FAHFA family members, PAHSAs are the most abundant in the adipose tissue of glucose tolerant AG4OX mice, which overexpress the Glut4 glucose transporter specifically in adipose tissue. 12-PAHSA is present at 2- to 3-fold higher levels in adipose tissue of AG4OX mice compared to wild type mice. Levels of 12-PAHSA are also higher in fasted wild-type mice compared to fed mice and are reduced upon high-fat diet-induced obesity in insulin-resistant mice.

9(R)-PAHSA is a stereoisomer of 9-PAHSA , an endogenous lipid that belongs to a collection of branched fatty acid esters of hydroxy fatty acids (FAHFAs).

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are newly identified endogenous lipids regulated by fasting and high-fat feeding and associated with insulin sensitivity. Structurally, these esters are comprised of a C-16 or C-18 fatty acid (e.g., palmitoleic, palmitic, oleic, or stearic acid) linked to a hydroxylated C-16 or C-18 lipid. 9-PAHSA is a FAHFA in which palmitic acid is esterified to 9-hydroxy stearic acid. PAHSAs are the most abundant forms of FAHFA in serum as well as white and brown adipose tissues of glucose tolerant AG4OX mice, which overexpress Glut4 specifically in adipose tissue. 9-PAHSA is the predominant isomer of PAHSA in wild type and AG4OX mice. It is found in humans and is reduced in the serum and adipose tissues of insulin-resistant humans. 9-PAHSA improves glucose tolerance, stimulates insulin secretion, and has anti-inflammatory effects in mice.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are lipids influenced by dietary changes, playing a crucial role in insulin sensitivity. These compounds typically consist of a C-16 or C-18 fatty acid (for example, palmitoleic, palmitic, oleic, or stearic acid) linked to a hydroxy fatty acid with the same carbon chain length. 13-PAHSA, a derivative where palmitic acid is esterified to 13-hydroxy stearic acid, is notably prevalent in the adipose tissue of glucose-tolerant AG4OX mice, which exhibit enhanced glucose transport via the overexpression of the Glut4 glucose transporter. This observation, along with the metabolic benefits seen from other FAHFAs—including improved glucose tolerance, stimulated insulin secretion, and anti-inflammatory properties—suggests that 13-PAHSA may function as a bioactive lipid beneficial in managing metabolic syndrome and inflammation.

Branched fatty acid esters of hydroxy fatty acids (FAHFAs) are a class of endogenous lipids whose levels are modulated by fasting and high-fat diets, and they play a role in insulin sensitivity. These compounds consist of a fatty acid—either a C-16 or C-18, such as palmitoleic, palmitic, oleic, or stearic acid—esterified to a hydroxylated C-16 or C-18 lipid. One notable FAHFA, 9-PAHSA, features an ester linkage between palmitic acid and 9-hydroxy stearic acid. PAHSAs, with 9-PAHSA being the most prevalent isomer, are significantly found in the serum and both white and brown adipose tissues of glucose-tolerant AG4OX mice, which express the Glut4 gene in adipose tissue, enhancing insulin sensitivity. Additionally, 9-PAHSA is abundant in wild type and AG4OX mice and present in humans, though at reduced levels in those with insulin resistance. 9-PAHSA is associated with improved glucose tolerance, enhanced insulin secretion, and anti-inflammatory effects in mice. The compound 19-PAHSA^13C4 represents an isotopically enriched form of this polyunsaturated fatty acid.

5-PAHSA, a FAHFA formed through the formal condensation of the carboxy group of palmitic acid with the hydroxy group of 5-hydroxystearic acid, serves as a human metabolite, possesses anti-inflammatory and hypoglycemic properties, and is categorized as a long-chain fatty acid. This compound, deriving from hexadecanoic acid and octadecanoic acid, is the conjugate acid of a 5-PAHSA(1-).

1-Palmitoyl-2-12-PAHSA-3-oleoyl-sn-glycerol, an endogenous triacylglycerol, comprises palmitic acid (at the sn-1 position), the fatty acid ester of hydroxy fatty acids (FAHFA), 12-PAHSA (at the sn-2 position), and oleic acid (at the sn-3 position). Identified in the lipid extract of mouse adipose tissue, this triacylglycerol demonstrates that levels of FAHFA-containing triacylglycerols are over 100-fold higher than those of non-esterified FAHFAs, suggesting their role as intracellular storage reservoirs for FAHFAs.
