the unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol

when they are underweight and continue to engage in unhealthy weight loss tactics. The video “Dying to be Thin” depicts a story with a young girl that is struggling with her weight and feels as though she is not thin enough. This girl begins to engage in actions like binging and purge eating in order to lose weight and continues to believe she is overweight. The girl in the video thrives to be thin and yearns for the control in her life of having an eating disorder. The article Anorexia nervosa: Friend

between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention on the stationary phase and thus affect the separation. Thin layer chromatography (TLC) is a chromatographic technique that we use to separate the components of a mixture using a thin stationary phase such as silica plate supported by an inert backing. It applies mainly in medical‚ biological‚ chemical and pharmaceutical sciences because it is easy to be done and saves

The articles and documentary‚” Dying to be thin” were very insightful and discussed the challenges of individuals with eating disorders such as anorexia nervosa and bulimia nervosa. These eating disorders are dangerous and can be fatal. Not only are there physical affects‚ but mental affects take place as well. In the documentary‚ pressures to be thin and the “ideal” body weight were discussed amongst aspiring dancers and models. In was reported that three out of one hundred girls will develop eating

I agree that people make snap decisions of others based on very little data. Growing up‚ most of us are taught to not make sudden assumption about others‚ nevertheless‚ we still do it. I agree that thin-slicing is a viable topic‚ which “refers the ability of our unconscious to find patterns in situations and behavior based on very narrow slices of experience” (Gladwell). I believe that everyone has the ability to find patterns in situations and behaviors‚ however‚ not everyone is capable of making

Model Thin “If you’re thin you are in ” is a recurring motto for many teenage girls. Being thin means they are beautiful‚ strong and can do whatever they want‚ or at least that’s what the media is trying to say.
