Effect of products of PLA2 catalyzed hydrolysis of DLPC on motion of rising bubbles

- The hydrolysis of 1,2-dilauroyl-sn-glycero-3-phosphocholine (DLPC) to lauryl acid (LA) and lyso-phosphatidylcholine (lyso-PC) was investigated at water/air interface.
- Velocities of rising bubbles decrease with appearance of the surface-active products of the enzymatic reaction.
- Lyso-PC has a dominating effect on bubble motion.
- The kinetics of transfer from spread layer to the solution is faster for lyso-PC than LA.
