This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

recommended in 2003 that consumption of trans fats be limited to less than 1% of overall energy intake. WHO also recommended that the Governments around the world should try to gradually phase out PHVO or trans fat. The US National Academy of Sciences (NAS) recommends that trans fatty acids are not essential and provide no known benefit to human health‚ whether of animal or plant origin.Secondly‚ while both saturated and trans fats increase levels of LDL‚ trans fats also lower levels of HDL‚ thus

How Acetylsalicylic Acid was Discovered Acetylsalicylic Acid in its earliest form was a powder for the bark and leaves of the willow tree. Hippocrates‚ who lived sometime between 460 B.C. and 377 B.C‚ founded it. This “Miracle Drug” that was able to relieve pains was later looked into with further detail by Johann Buchner. He isolated a tiny amount of bitter tasting yellow‚ need- like crystals‚ and called salicin. By 1829 French Chemist Henri Leroux had improved the extraction procedure to

Trans-Atlantic Slave Trade (Essay) The Trans-Atlantic slave trade had a massive impact the British‚ West Indies‚ Africa‚ and the emerging African American culture. The British were impacted with massive profits‚ to the disadvantage of many parts of Africa‚ where large amounts of men and women from all around the continent were forced into slavery. The West Indies were impacted by being turned into sugar plantations‚ and an African American Culture was born from all the African slaves that were

Central‚ and South America. These two overlapping waves of transcontinental slave trading made the slave trade central to the economies of many African states and threatened many more Africans with enslavement‚ and can to be known as the Trans-Saharan and Trans-Atlantic Slave Trade. The merchants who traded slaves on the coast to European ship captains – for example the Vili traders north of the Congo‚ the Efik in the Bight of Biafra‚ and behind them the groups

Punished by Acid Several people from the third world become a victim of an acid attack. The victim’s life has changed tremendously‚ which is what the photographer shows with his world-known pictures. On Ebrahim Noroozi’s photoseries you see a mom named Somayeh and her daughter‚ Rana and what acid has done to their faces. Now they most stay by themselves and take care of themselves. It is hard for me to understand some people will walk up to you to pour acid on you. Somayeh looked like an average
