Very long-chain fatty acids are fatty acids with an aliphatic tail that contains at least 22 carbon atoms. Thus, lignoceric acid is considered to be a fatty acid lipid molecule. Lignoceric acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Lignoceric acid can be found in a number of food items such as hazelnut, cheese, rye bread, and cetacea (dolphin, porpoise, whale), which makes lignoceric acid a potential biomarker for the consumption of these food products. Lignoceric acid can be found primarily in blood and feces, as well as in human fibroblasts tissue. Lignoceric acid exists in all eukaryotes, ranging from yeast to humans. In humans, lignoceric acid is involved in a couple of metabolic pathways, which include adrenoleukodystrophy, x-linked and beta oxidation of very long chain fatty acids. Lignoceric acid is also involved in carnitine-acylcarnitine translocase deficiency, which is a metabolic disorder. Lignoceric acid, or tetracosanoic acid, is the saturated fatty acid with formula C23H47COOH. It is found in wood tar, various cerebrosides, and in small amounts in most natural fats. The fatty acids of peanut oil contain small amounts of lignoceric acid (1.1% – 2.2%). This fatty acid is also a byproduct of lignin production .C24H48O2368.6367368.36543078tetracosanoic acidlignoceric acid557-59-5CCCCCCCCCCCCCCCCCCCCCCCC(O)=OInChI=1S/C24H48O2/c1-2-3-4-5-6-7-8-9-10-11-12-13-14-15-16-17-18-19-20-21-22-23-24(25)26/h2-23H2,1H3,(H,25,26)QZZGJDVWLFXDLK-UHFFFAOYSA-N belongs to the class of organic compounds known as very long-chain fatty acids.
