Osmotic pressure is a measure of the extra pressure that has to be exerted to counteract osmosis. The osmotic pressure of a solution is the force that has to be exerted to halt osmosis. If a U-shaped glass tube were divided in two by a semipermeable...

Osmotic pressure is the hydrostatic pressure produced by a solution in a space divided by a semipermeable membrane due to a differential in the concentrations of solute. Osmoregulation is the homeostasis mechanism of an organism to reach balance in...

ABSTRACT We measured the osmotic pressure of diffusible myoplasmic proteins in frog (Rana temporaria) skeletal muscle fibers by using single Sephadex beads as osmometers and dialysis membranes as protein filters. The state of the myoplasmic water was probed by determining the osmotic coefficient of...

ABSTRACT The osmotic pressure of chondroitin sulfate (CS) solution in contact with an aqueous 1:1 salt reservoir of fixed ionic strength is studied using a recently developed coarse-grained molecular model. The effects of sulfation type (4- vs. 6-sulfation), sulfation pattern (statistical distribution of...
