Mineralized tissues

The main structural elements involved in the mollusk shell formation process are: a hydrophobic silk gel, aspartic acid rich protein, and a chitin support. The silk gel is part of the protein portion and is mainly composed of glycine and alanine. It is not an ordered structure. The acidic proteins play a role in the configuration of the sheets. The chitin is highly ordered and is the framework of the matrix. The main elements of the overall are:
#The silk gel fills the matrix to be mineralized before the mineralization takes place. #The highly ordered chitin determines the orientation of the crystals. #The components of the matrix are spatially distinguishable. #Amorphous calcium carbonate is the first form of the mineral. #Once nucleation begins on the matrix, the calcium carbonate turns into crystals. #While crystals grow, some of the acidic proteins get trapped within them.
