| Research Abstract |
It has been hypothesized that biomineralization, an action of mineral formation by organisms, is regulated by a small amount of organic materials included in biominerals. Using calcified tissues of some aquatic organisms we searched for calcification-regulating organic compounds, and purified them for structural and functional identification. We also clarified the crystallographic properties of each calcified tissue by electron microscopic analyses and verified the hypothesis by discovering many high- and low-molecular-weight organic compounds, which regulate calcification.
