Which are true about fibrous proteins ?
a) polypeptide chains coil around.
b) generally insoluble in water.
c) eg . myosin
a,b
a,b,c
b,c
a,c
As we have learnt,
Fibrous protiens have several polypeptide chains running parallel which are held together by bonds and disulphide bonds
Eg. Keratin , Collagen Myosin (muscle protein)
It is Globular protein in which there is a coiling of polypeptide chains to give a spherical shape.
Hence, statements (b) and (c) are correct.
Therefore, the correct answer is Option (3)
