1,2-Dipalmitoyl-sn-glycero-3-PG (1,2-DPPG) is a phospholipid containing the long-chain (16:0) palmitic acid inserted at the sn-1 and sn-2 positions. It can be used in the generation of micelles, liposomes, and other types of artificial membranes.
1,2-Dipalmitoyl-sn-glycero-3-PG (sodium salt) (UV radiation exposure) suffers cleavage of C―O, C=O and -PO2- bonds and loses monolayer stability; when DNA exists in the subphase, ionic degradation products from DPPG and DNA stabilize intact DPPG molecules and mitigate UV irradiation damage.

1,2-Dipalmitoyl-sn-glycor-3-PG (sodium salt) undergoes C-O, C=O, and - PO2-chemical bond cleavage upon exposure to ultraviolet radiation, leading to a decrease in the stability of the monolayer film; When DNA is present in the subphase, 1,2-Dipalmitoyl-sn-gycero-3-PG (sodium salt) and the ion products generated by DNA degradation can stabilize and complete DPPG molecules, reducing damage caused by UV irradiation.
