Shells of a modern scallop, Patinopecten yessoensis were heat-treated in order to examine diagenetic changes in amino acid compositions of conchiolin proteins. Amino acid compositions of the insoluble fractions after the heating are different from that of the original, but resemble to the compositions of the fossil shells, showing less aspartic acid and serine contents. These changes are probably due to the presence of different conchiolin proteins of the scallop, and discussed in relation to the change of amino acid compositions of the scallop during diagenesis.
