PROTEINS ON THE BASIS OF STRUCTURE
1.Simple proteins
● albumins
● globulins
● glutelins
● prilamins
● albuminoids
2.Conjugated proteins
● nucleoproteins
● glycoproteins
● phosphoproteins
● lipoproteins
● metallo proteins
3.Deived proteins.
proteins have four structures
1.primary structure
2.secondary structure
● alpha helix
● beta pleated sheets
● collagen or tropocollagen helix
3.Tertiary structure
4.Quaternary structure.
