“Use of Biuret Reagent to Test for Proteins In Food” Cindy Zhou Introduction Protein is a series of amino acids that are connected together by peptide bond. The bond is located between the end of previous amino acid‚ which is the carboxyl group‚ and the head of next amino acid‚ which is a amino group. The Biuret reagent is a solution of copper sulfate and potassium hydroxide. When peptide bond are presented‚ the copper (II) will interact with them (MadSci Network: General Biology). It is

Determination of Protein Content Using Kjedahl and Titration 2.0 Introduction Proteins are polymers. They are the source of dietary amino acids and are used for growth and maintenance of living systems. They are costlier sources of energy compared to carbohydrates and fats and hence the human body utilizes proteins mainly for biosynthesis rather than as an energy source‚ though the energy yield is 5 kcal/g of protein. Twenty different types of amino acids occur naturally in proteins. Proteins differ

four food apple sauce‚ carrot juice‚ cracker juice‚ and turkey juice contain protein‚ starch‚ or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice.

BIURET FOOD TEST FOR PROTEINS molecules consisting of one or more chains of amino acids.Proteins are complex molecules that react differently to many compounds but are also fragile and cannot withstand high temperatures or strong acids and bases without degrading. The Biuret Method‚ or biuret test‚ is used to detect the presence of peptide bonds. It has this name because it reacts positively to the biuret molecule’s peptide bonds. Correctly evaluating the number of peptide bonds is a step towards
