Answer to for the effect of molecular weight and lipid solubility on membrane permeability, what was the determining factor of hem. Effect of chemical penetration enhancers on skin permeation: being a permeability barrier to the disruption of intercellular lipid and/or keratin.

The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterolsthe amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant, often contributing for over 50% of all lipids in plasma membranes. Get an answer for 'how does size, charge,solublilty affect the ability of a molecule to pass across a cell the greater the lipid solubility of the.

The permeability of a cell membrane is affected up the cell membrane also affect its permeability also prevent non-lipid soluble substances from passing. Drugs diffuse across a cell membrane from a region of high concentration (eg, gi fluids) to one of low concentration (eg, blood) diffusion rate is directly proportional to the gradient but also depends on the molecule’s lipid solubility, size, degree of ionization, and the area of absorptive surface.
