Notes: 3-hydroxy Palmitic acid is a form of the 16:0 lipid palmitic acid (Item No. 10006627). The lipid A part of lipopolysaccharides contain various 3-hydroxy fatty acids, making oxylipins such as 3-hydroxy palmitic acid useful as chemical markers of endotoxins.{31684} In R. solanacearum, 3-hydroxy palmitic acid is converted by an S-adenosyl methionine-dependent methyltransferase to 3-hydroxy palmitic acid methyl ester, which acts as a quorum sensing signal molecule for post-transcriptional modulation of genes involved in virulence.{31682} Long-chain 3-hydroxy fatty acids, such as 3-hydroxy palmitic acid, are also known to accumulate during long-chain 3-hydroxy-acyl-CoA dehydrogenase and mitochondrial trifunctional protein deficiencies.{31683} Such accumulation induces oxidative stress, leading to mitochondrial bioenergetics deregulation and eventual multi-organ dysfunction.{31683}
