The essential amino acid phenylalanine‚ with the molecular formula C9H11NO2‚ is abbreviated in the 3 letter form as Phe‚ or the single letter F‚ and is classified as a nonpolar amino acid due to the hydrophobic nature of the benzyl side chain (UPAC-IUBMB Joint Commission on Biochemical Nomenclature‚ 1983). The presence of the benzene ring determines that phenylalanine is an aromatic amino acid. Phenylalanine‚ being an essential amino acid‚ is needed by the body for many necessary biological functions

Molisch ’s test is a sensitive chemical test for the presence of carbohydrates‚ based on the dehydration of the carbohydrate by sulphuric acid to produce an aldehyde‚ which condenses with two molecules of phenol‚ resulting in a red- or purple-colored compound. Benedict ’s test allows for the detection of the presence of reducing sugars (sugars with a free aldehyde or ketone group). All

and industrial applications. Citric Acid is one of the organic acids commonly used as a chelating agent. It is considered an excellent chelating agent that binds metals. It is used to remove lime scale from boilers and evaporators. It can be used to soften water‚ which makes it useful in soaps and laundry detergents. By chelating the metals in hard water‚ it lets these cleaners produce foam and work better without need for water softening devices. Citric acid is the active ingredient in some bathroom

The basic building blocks of proteins are amino acids‚ the biuret reaction tests for protein. A solution of sodium hydroxide is added to a sample then a few drops of copper sulphate solution‚ if positive – the solution will turn mauve. There are 20 different amino acids and they can be joined in any order. Therefore there can be many different functions. A protein consists of one or more polypeptide chains (a polypeptide chain being multiple amino acids joined together via condensation‚ producing

Protein SCI/241 Protein A protein are organic compounds that made up of amino acids and are the building blocks of the cells in the body. Every cell in the body requires proteins to grow and repair themselves so these proteins are necessary for a healthy body and survival. Having so much protein can hurt your body so when you consume so much can get you sick and the right size of protein can keep you from getting sick. They’re five types of protein in everything that we eat. The largest class
