Abstract

Biomineralizacija je složen skup biokemijskih i fizioloških procesa pomoću kojih živi organizmi stvaraju čvrste strukture - biominerale. U morskim organizmima procesi biomineralizacije započinju u ranim embrionalnim razvojnim stadijima, odvijaju se tijekom čitavog životnog ciklusa, a očituju se u kalcifikaciji, dekalcifikaciji i polimorfnim promjenama minerala u tkivima, ljušturama ili skeletima. Proces biomineralizacije ovisi o unutarnjoj aktivnosti organizma, te utjecajima okoliša. Jedan od enzima koji sudjeluju u procesu biomineralizacije je ugljična anhidraza koja katalizira reakciju hidratacije i dehidracije \(CO_2\). Proučavanje mehanizama biomineralizacije je jako popularno zbog široke primjene minerala nastalih tim procesom.<br />Biomineralization is a complex combination of biochemical and physiological processes, during which living organisms produce solid structures - biominerals. In marine organisms, biomineralization processes begin in early embryonic developmental stages and occur throughout the entire life cycle, which is manifested in calcification, decalcification and polymorphic changes of minerals in tissues, shells or skeletons. The biomineralization process depends on endogenous activity of an organism and the exogenous environmental influence. One of the enzymes involved in the biomineralization process is carbonic anhydrase that catalyzes the reaction of hydration and dehydration of \(CO_2\). Biomineralization mechanisms are very popular because of the wide application of minerals created by this process.
