Gelatin, a mixture of heterogeneous, water-soluble proteins present in collagen and isolated by boiling the tendons, ligaments, bones, and relevant skin with water.
BACKGROUND Principle: Here a modified Friedel-crafts acylation reaction is occurring. This reaction is a series of electrophilic aromatic substitutions, with hydroxyl leaving groups picking up protons by Lewis acid catalysis. It increases the electrophilicity of pthalic anhydride in the first step, and facilitates the elimination of the hydroxyl groups....
Methyl-Red Test is one of the important biochemical test performed on bacterial species for studying about the ability of an organism to perform mixed acid fermentation from given glucose. It is a part of IMViC test.
