What are the types of proteins in metabolism of lens?
Soluble Proteins
Its synthesis takes place in the equatorial part on the surface of lens.
a. Alpha crystallins
b. Beta crystallins
c. Gamma crystallins
Insoluble Proteins
When alpha crystallins combine with disulphide linkage or C-S bond, the insoluble fractions are formed, Insoluble fractions are urea or alkali soluble fractions, other Lens proteins: These are glycoproteins, nucleoproteins, phosphoproteins, lipoproteins and fluorescent protein.
