Lipids and Phospholipids The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers.

Introduction Diffusion and osmosis are two types of passive transport. Diffusion is a random movement of molecules from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion that diffuses water through a selectively permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane

lab is to measure urinary glucose (a known and unknown sample) using two quantitative tests: colorimetric strip test and o-toluidine test. Urinary glucose is the main focus for this lab due to its involvement with diabetes‚ a disease defined by the abnormal regulation of insulin. The most effective method for monitoring glucose is through blood glucose compared to urinary glucose. It has been discovered that urinary glucose is not a good measure of changes in blood glucose because: (1) the bladder
