Fatty Acids & Lipids

Lipids are biological molecules that are soluble in nonpolar solvents and insoluble in aqueous solution. The main physiological functions of lipids in human physiology include signaling, working as structural components of biological membranes, and providing energy reserves mainly in the forms of triglycerides. Lipids are classified into different types, including fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, polyketides, and sterol lipids and prenol lipids. A fatty acid, the common component of complex lipids, is a carboxylic acid with a long aliphatic chain. Based on their chain structure and functional groups, fatty acids can be classified into different types, including normal fatty acids (straight chain), branched chain fatty acids, ring containing fatty acids, and fatty acyl-CoA. In the body, fatty acids can work as the precursor for the synthesis of bioactive lipids and play an important role in biological processes and in the construction of biological structures. Outside the body, they can be used in the production of soaps, detergents, and cosmetics.

As a supplier of isotope labeled products in the industry, Creative Proteomics offers more than 10,000 products labeled with different isotopes of carbon, hydrogen, nitrogen, and oxygen. Creative Proteomics supplies stable isotope labeled and unlabeled fatty acids and lipids, such as lauric acid, heptanoic acid, and oleic acid. These lipids and fatty acids standards are utilized in various areas, including clinical and diagnostic testing, biomarker discovery, analysis of functional foods or nutraceutical formulations, food matrix testing, and microbiology. Custom synthesis of isotope labeled fatty acids and lipids is also available to meet our customers’ research needs.
