Blood Glycolysis

Abstract-(Add more info) Molecular weight is one factor that affects a soupcons ability to cross a sales booths membrane. To determine how different the spreading set ups would be for differing molecular weights, 1mL of a ovine release line of swop stall suspension was added to 4mL of ethylene dihydric alcohol (62.07 Daltons), diethylene glycol (106.10 Daltons), or triethylene glycol (150.17 Daltons). To accurately monetary standard the rate of diffusion, a lettuce-lamp was used to measure the hemolysis time in seconds. The ovine red origin cell suspension was hypertonic to for each one of the glycol treatments, which meant that the cells big and ruptured when they spread out. Once the horizontal thread of the slit was visible, 75% of the red blood cells were hemolyzed, and the time was stopped and recorded. The slew of the data indicated that as the molecular weight increased so did the time for the molecule to hemolyze, except for ethylene glycol. Diethylene g lycol diffused faster because of its polarity. We hypothe sized that size would have an impact on the osmosis rate of the glycols. The time it took for the blood cell to lyse was significantly longish in the larger glycol, triethylene. haematolysis rate was tested lodge times on ternary different size glycols. The diethylene had the fastest diffusion rate, while triethylene took the longest.

surface could cause different range of diffusion in glycols. Therefore, the rate of diffusion is directly relative to the size of the glycol molecule. Introduction- (Do research) on the whole cells and organisms require diverse molecules and nutrients to principal(prenominal)tain life. T he purpose of the selectively semipermeable! membrane, called the phospho lipoid bilayer, is to abet in the regulation of these molecules. There argon deuce-ace main ways molecules can cross the membrane: the lipid bilayer, aqueous channels (or aquaporins), and carrier-mediated transport. Furthermore, other factors that determine the rate of diffusion are size and polarity.
