3-hydroxy stearic acid

3-hydroxy Stearic Acid (3-hydroxystearic acid) 是从假单胞菌和菌丝桃属植物中发现的一种脂肪酸。

3-Hydroxy Stearic acid methyl ester, a hydroxylated fatty acid methyl ester, occurs in methyl-branched poly(3-hydroxyalkanoate) (PHA) polymers synthesized by Streptomyces sp. JM3 and is present in trace amounts in M. bijuga fruit. Additionally, it is identified as a chemical scent constituent in the feces of adult wild Iberian wolves (C. lupus signatus). [Matreya, LLC.

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-hydroxy Stearic Acid 是一种羟基脂肪酸，是9-PAHSA 的活性代谢物。9-hydroxy Stearic Acid 是由9-PAHSA 通过肝脏和胰腺的羧基酯脂肪酶形成的。9-hydroxy Stearic Acid (5 μM)抑制HT-29结肠癌细胞裂解物中组蛋白去乙酰化酶1 (HDAC1)的表达。3 .当浓度为100 μM.1时，可抑制HT-29细胞的增殖，并诱导细胞周期阻滞于G0 g1期。

1-Stearoyl-2-hydroxy-sn-glycero-3-PG, a lysophospholipid characterized by the presence of stearic acid (18:0) at the sn-1 position, finds application in the creation of micelles, liposomes, and various artificial membranes, including those utilized in lipid-based drug delivery systems.
