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
Which of the following combinations of above statement is true?
