Abstract:

Histochemical, solubility, thermal, infrared spectral, elemental and amino acid analysis methods were used for chemical characterization of the barnacle cement. Histochemical methods suggest mainly proteinaceous material containing free amino groups and some reducing groups. Solubility and thermal analyses indicate a highly crosslinked proteinaceous substance. The infrared spectra of the barnacle cement is characteristic of proteins, but the possible presence of some carbohydrate is also indicated. Elemental analysis verified the proteinaceous character of the cement to the extent of up to 80 percent of the dry material. The amino acid profile of the protein fraction was also determined.
