1.	These are cross linked proteins and are condensation product of acidic and basic amino acids.	These are linear condensation polymer
2.	These are soluble in water, mineral acids and bases.	These are insoluble in water but soluble in strong acids and bases.
3.	These proteins have three dimensional folded structure. These are stabilised by internal hydrogen bonding. e.g., egg albumin enzymes.	These are linear polymers held together by intermolecular hydrogen bonds. e.g., hair, silk.
