Background:


Docosahexaenoic acid 1,2,3,4-13C (DHA 1,2,3,4-13C) is intended for use as an internal standard for the quantification of DHA by GC- or LC-MS. DHA is a long-chain ω-3 polyunsaturated fatty acid (PUFA) found in fish and algal oils.1It comprises approximately 40% of total brain PUFAs and is abundant in grey matter and retinal membranes.2DHA typically represents 0.52-7.5% of human total plasma fatty acids. It is produced from α-linolenic acidviaa series of desaturase- and elongase-catalyzed reactions, resulting in a docosapentaenoic acid intermediate, which is elongated, desaturated, and β-oxidized to produce DHA.3DHA can be liberated from cellular membranes by phospholipase A2(PLA2) and converted to numerous oxylipins, including specialized pro-resolving mediators (SPMs), which are produced by lipoxygenases and include D-series protectins and resolvins, as well as maresins, that regulate host defense and the resolution of inflammation.4DHA has roles in several physiological and pathological processes, including neural development, cardiovascular diseases, obesity, and inflammation.3,5
