During mollusk shell formation, the mineral phase forms within an organic matrix composed of beta-chitin, silk-like proteins, and acidic glycoproteins rich in aspartic acid. The matrix is widely assumed to play an important role in controlling mineralization. Thus, understanding its structure is of prime importance. Cryo-transmission electron microscopy (Cryo-TEM) studies of the matrix of the bivalve Atrina embedded in vitrified ice show that the interlamellar sheets are composed mainly of… CONTINUE READING
