The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols

Crossing the Line How would you react if you were told you have the power to design your first child? Would you be disgusted with the thought? Would you be curious about this new process? This is a question that has been popping up more and more at fertility clinics across the nation. This interesting process is known as pre-implantation genetic diagnosis (PGD). Basically‚ PGD is a technique whereby a three-day-old embryo‚ consisting of about six cells‚ is tested in a lab to see if it carries

Separating Water Soluble and Acetone Soluble Inks through Chromatography Abstract: Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent lab we measured the distance traveled by the different colored water and acetone soluble
