Abstract

  • 1.

    1. While global nacre conchiolin shows in its composition the predominantly concentrations of four amino acids: glycine, alanine, serine and aspartic acid, global prism conchiolin shows a different pattern, characterized by two predominantly amino acids: glycine and aspartic acid.

  • 2.

    2. Prism conchiolin has been isolated from fossil shells of Pinna affinis (London, Clay, Lower Eocene) and Inoceramus sp. (Gault, Cretaceous). The comparison of modern and fossil prism conchiolins shows differences in the pattern of amino acid composition. The significance of these differences is discussed.
