This reduc-es surface tension and creates a thin, even release barrier not to see other 2 answers. Lecithin has a simultaneous affinity for both oils and water, which makes it an effective ingredient in pan releases and oth-er lubricants. Hence, the disaturated lecithins from these sources were essentially all dipalmitoyl lecithin. Wehave developed a convenient and … Acts preferentially with unsaturated acyl-CoA derivatives. Lecithin is essential for proper biological function. A commercial form of lecithin is commonly used in the preparation of food, cosmetics, and medications, as it extends shelf life and acts as an emulsifier.

When phosphatidylcholine is taken by mouth, it can sometimes cause excessive sweating, stomach upset, and diarrhea.. Phosphatidylcholine injections can cause irritation, swelling, redness, itching, burning, bruising, and … The results suggest that lecithin could act as a steric surfactant to increase the surface charge density of SCA, generating sufficient electrostatic repulsive forces between the adjacent solid surface of SCA clusters to prevent their premature self-aggregation in an aggregated form during the nucleation stage . We argue that this is the main reason for a similar decrease in pH for lecithin based emulsions and subsequent instability in drug laden emulsions. Also acts on phosphatidylethanolamine, choline plasmalogen and phosphatides, removing the fatty acid attached to the 2-position. All rabbit tissues analyzed contained disaturated lecithins, but they accounted for more than 10% of the total lecithins in lung, brain, alveolar macrophages, and polymorphonuclear leukocytes only. 1-Acyl-sn-glycero-3-phosphoinositol can also act as acceptor.
