Which of the following test is used for the detection of aldoses?
The enzyme which cuts from the N-terminal side of the amino acids having Leu, Asp and Glu amino acids is/are
Given, all the enzymes except pepsin cuts from the C-terminal side.
The protecting group of amines which is deprotected by base is
The number of π-electrons which are in delocalization in pyridine ring is/are____
there are three π-bonds in pyridine ring. So, that total of 6π-electrons are invoved in delocalization. Hence, aromatic.
Among the following sugars which gives both Bromine water and Tollen’s Test positive is/are
D-glucose, D-Fructose, D-mannose, D-iodose
D-glucose, D-mannose and D-iodose all have aldehydic functional group and gives both positive tests.
While as D-fructose have ketonic functional group and gives negative bromine water test, but positive Tollen’s test.
