Glyco protein are conjugated protein. They have sugars as their prosthetic group.
Fibrous protein have linear thread like molecules. They are structural material for animal tissue, e.g.~ keratin, hair, nail etc.
In Globular protein, polypeptide chains of these proteins coil around itself to give protein molecule spheroidal shape e.g., all enzymes, antibodies, haemoglobin, alburnim etc.
Hence, haemoglobin is an example of globular protein.
