Equanil
Naproxen
Tetracycline
Chlorpheninamine
The hormone which controls the processes like burning of fats, proteins and carbohydrates to liberate energy in the body is
cortisone
thyroxine
adrenaline
insulin
Which one of the following structures represents the peptide chain ?
The number of molecules of ATP produced in the lipid metabolism of a molecule of palmitic acid is
130
36
56
86
The cell membranes are mainly composed of
carbohydrates
proteins
phospholipids
fats
On hydrolysis of starch, we finally get
glucose
fructose
both (a) and (b)
sucrose
Number of chiral carbon atoms in βD(+) glucose is
five
six
three
four
Sucrose in water is dextrorotatory, [ α ]D = + 66.4o when boiled with dil HCI, the solution becomes leavo - rotatory , [α ]D = -39.9o .
In this process the sucrose breaks into
L-glucose + D-fructose
L-glucose + L-fructose
D-glucose + D-fructose
D-glucose + L-fructose
In DNA, the complementary bases are
adenine and thymine, guanine and cytosine
uracil and adenine, cytosine and guanine
adenine and guanine, thymine and cytosine
adenine and thymine, guanine and uracil
Which statement is incorrect about peptide bond
C — N bond length in proteins is longer than usual bond length of C — N bond
Spectroscopic analysis show planar structure of group
C — N bond length in proteins is smaller than usual bond length of C — N group
None of the above
