Denatured protein has gone bad and should not be eaten has l
Solution
Solution:
 5.(B)Proteins are made up of amino acids.These amino acids chains folded up three dimensionally and give rise to protein\'s primary and secondary structure.When denaturation of protein occur due to heat or some other source its three dimensional structure is disrupted.And the function of protein is directly related to its secondary and tertiary structure.
6.(C)A disaccharide consist of two monomers of sugar or we can say that two monosaccharides of simple sugar.These two monosaccharides joined mainly by glycosidic linkage.
7.(D)Steroids are hydrophobic and not soluble in water.Due to their hydrophobic nature they can easily pass through the cell membranes.
8.(B)Thymine base is present in DNA molecule.In RNA,thymine is replace by uracil.
