Stress alleviating membrane

The results of this study showed that short term Cd treatment can stimulate both SOD activity and MDA content, and the ROS increased at the same time, indicating that excessive ROS content could aggravate oxidative damage to the cell membrane. Low concentrations of SA and LaCl3 could alleviate Cd stress, and the combination of 20 mg/L SA and 60 mg/L LaCl3 gave the best results (better that either... 

Increasing the thickness of the carboxylic acid layer tends to alleviate mechanical damage and stress on the membrane. Beyond a certain thickness, however, this effect diminishes and an optimum thickness also exists in this regard. 

In both membrane cnrvature sensing and indncing by facial amphiphilic helices, the mechaiusm has to do with incorporation of the heUx into the bilayer. In the case of membrane curvature sensing incorporation is driven by alleviating the membrane stress, present in curved membranes. In the case of membrane curvature inducing proteins a facial amphiphilic alpha helix is forced into the bilayer, for example, binding of a protein domain to the phospholipids, which results in bilayer curving.
