A protein-free liposome with an initial volume of 5nl contains an impermeant (uncharged) organic solute at a concentration of 0.25M and a concentration of Na+ of 0.1M. What will be its final volume when placed in a solution containing 0.1M NaCl? In addition what are the final concentrations of the internal organic solute and [Na+] at equilibrium? Is the 0.1M NaCl solution hypertonic, isotonic, or hypotonic?

74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...
A. What is the Isoelectric point pI of the peptide Gly-Glu-Ala-Lys-Val ? B. A purified protein is in a Hepes buffer at pH 7 with 300 mM NaCl. A sample (2mL) of the protein solution is placed in a tube made of dialysis membrane and dialyzed against 1 L of the same Hepes buffer with no NaCl. Small molecules and ions (such as Na+, Cl-, and Hepes) can diffuse across the dialysis membrane, but the protein cannot. 1. Once the...

Question two
A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 ml solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O2. The initial concentration of both the acid and the base are 0.0100 mol/0.1000...

INTRODUCTION Albumin is synthesised in the liver at a rate that is dependent on dietary protein intake. Little is lost from the body by excretion. It is catabolized in various tissues, where it is taken up by cells by pinocytosis. Albumin has a vast capacity for ligand binding due to the large number of charges on each molecule as well as the very large number of molecules available. This binding property of albumin is related to one of its functions,...
