Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, 10,16-dihydroxyhexadecanoic acid is considered to be a fatty acid lipid molecule. 10,16-dihydroxyhexadecanoic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 10,16-dihydroxyhexadecanoic acid can be found in garden tomato (variety) and gooseberry, which makes 10,16-dihydroxyhexadecanoic acid a potential biomarker for the consumption of these food products. 10,16-Dihydroxy-hexadecanoate 10,16-Dihydroxypalmitic acid C16H32O4 288.4229 288.230059512 10,16-dihydroxyhexadecanoic acid 10,16-dihydroxy-palmitic acid 3233-90-7 OCCCCCCC(O)CCCCCCCCC(O)=O InChI=1S/C16H32O4/c17-14-10-6-5-8-12-15(18)11-7-3-1-2-4-9-13-16(19)20/h15,17-18H,1-14H2,(H,19,20) VJZBXAQGWLMYMS-UHFFFAOYSA-N belongs to the class of organic compounds known as long-chain fatty acids.
