Ether bonds, hydrolytic enzymes

Most cells continually degrade and replace their membrane lipids. For each hydrolyzable bond in a glycerophospholipid, there is a specific hydrolytic enzyme in the lysosome (Fig. 10-15). Phospholipases of the A type remove one of the two fatty acids, producing a lysophospholipid. (These esterases do not attack the ether link of plasmalogens.) Lysophospholipases remove the remaining fatty acid. 

It has been shown that there exists the possibility of accelerating electrochemical reactions by means of enzymes catalyzing the hydrolytic cleavage of covalent, for instance, ether, bonds. If a compound RX undergoes an electrochemical transformation at high overvoltage...
