Ballantyne, in Encyclopedia of Fish Physiology, 2011 Deacylation–reacylation. Deacylation –reacylation in cold acclimation replaces a less unsaturated acyl chain (e.g., 18:1) with an unsaturated fatty acid (e.g., 22:6n-3). The reassigning of acyl chain positions within a PL may be an important role for this process, … WebWater and organic alcohols react with acyl chlorides and acetic anhydrides very similarly to ammonia and amines; the only difference is that the products are carboxylic acids if they react with... laundry service westminster
