Thermodynamic measurements indicate that native proteins are only marginally stable under physiological conditions, The free energy required to denature them is ∼0.4 kJ∙mol−1 per amino acid residue so which of the following is true for so a fully folded 100-residue protein

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. To denature them only 40 kJ.mol−1 is required, which is equal to the breaking of one hydrogen bond
  2. To denature them only 40 kJ.mol−1 is required, which is equal to the breaking of two hydrogen bond
  3. To denature them only 40 kJ.mol−1 is required, which is equal to the breaking of three hydrogen bond
  4. To denature them only 40 kJ.mol−1 is required, which is equal to the breaking of four hydrogen bond

Cyanogenic Glycosides and Glucosinolates are nitrogen containing secondary metabolites in plants. Following are some statements regarding the action of Cyanogenic Glycosides and Glucosinolates;

a) Cyanogenic Glycosides release the poison hydrogen cyanide by the action of enzyme known as Hydroxynitrile lyase

b) Release of the mustard-smelling volatiles from glucosinolates is catalyzed by a hydrolytic enzyme, called a thioglucosidase or myrosinase

c) substerate for Glycosidase is Cyanogenic glycoside and Thioglucosidase is Aglycone

d) Like cyanogenic glycosides, glucosinolates are stored in the intact plant separately from the enzymes that hydrolyze them, and they are brought into contact with these enzymes only when the plant is crushed
