source of minerals and vitamins and is rich in total water soluble sugars‚ free reducing sugars‚ amide proteins among other nutrients. It has been reported that on an average‚ the oblong-fruited eggplant cultivars are rich in total soluble sugars‚ whereas the long-fruited cultivars contain a higher content of free reducing sugars‚ anthocyanin‚ phenols‚ glycoalkaloids (such as solasodine)‚ dry matter‚ and amide proteins (Bajaj et al. 1979). For processing purposes‚ the fruit should have high dry matter

amino acids with non-polar side chains. Rank the following according to increasing non-polarity i.e. 1 = least non-polar‚ 4 = most non-polar. leu; phe; val; ala Polar Side Chains: Side chains which have various functional groups such as acids‚ amides‚ alcohols‚ and amines will impart a more polar character to the amino acid. The ranking of polarity will depend on the relative ranking of polarity for various functional groups as determined in functional groups. In addition‚ the number of

ISOLATION OF GLUTEN FROM WHEAT FLOUR AND ITS COLOR REACTION IN DIFFERENT QUALITATIVE TESTS Abstract: Gluten is isolated from wheat flour by washing it with water‚ dissolving the flour’s water soluble components and therefore separating gluten from it. The isolated gluten was then used in different qualitative colour reaction tests. These tests determine what amino acids are present in a protein‚ in this case gluten. Introduction: Proteins are large biological molecules that are made up of amino

pure sample was 76%. The melting point of the pure sample was 167C - 169C. Introduction: Formulation of acetaminophen involves treating an amine with an acid anhydride to give rise to an amide. In this experiment‚ p-aminophenol‚ the amine‚ is treated with acetic anhydride to form acetaminophen‚ the amide. The crude acetaminophen was expected to be dark in color. This was due to the fact that the impurities were formed from oxidation of the starting phenol. The intensity of this was enough to
