Background

Docosanoic acid-d₄ is intended for use as an internal standard for the quantification of docosanoic acid by GC- or LC-MS. Docosanoic acid is a long-chain saturated fatty acid. It has been found in peanut and M. oleifera seed oils.^1,2 It inhibits the double-stranded DNA binding activity of p53 through a direct interaction with the DNA binding domain (K_d = 12 nM).³ Docosanoic acid inhibits rat DNA polymerase β and human DNA polymerase Λ activity in cell-free enzyme assays when used at a concentration of 100 µM and inhibits human DNA topoisomerase I and II relaxation activity at a concentration of 25 µM.⁴ Liver levels of docosanoic acid are reduced in rats fed a high-fat or a high-fat high-cholesterol diet but not a high-cholesterol diet.⁵ Formulations containing docosanoic acid have been used in hair conditioner and moisturizers.
