ABSTRACT: 1.1. A purified vitellin was isolated from the mature ovaries of the prawn (Penaeus monodon) after purification with gel filtration, hydroxylapatite, DEAE-Sephacel and polyacrylamide gel electrophoresis.2.2. Eight polypeptide subunits and a molecular weight of 492 kDa were suggested as being present in the purified vitellin.3.3. Polypeptide subunits are associated with each other through non-disulfide bonds, and the subunits of the purified vitellin were easily rearranged during the purification.4.4. It has been suggested that the purified vitellin is a lipo-glyco-carotenoprotein. The amino acid composition of the vitellin has also been analyzed.
