What is conchiolin made from?
What is conchiolin made from?
Conchiolins (sometimes referred to as conchins) are complex proteins which are secreted by a mollusc’s outer epithelium (the mantle). These proteins are part of a matrix of organic macromolecules, mainly proteins and polysaccharides, that assembled together form the microenvironment where crystals nucleate and grow.
What does conchiolin mean?
: a scleroprotein forming the organic basis of mollusk shells (as mother-of-pearl) — see nacre sense 2.

Are pearls strong?
Pearls and mother-of-pearl are both made from nacre, an organic-inorganic nanocomposite material. It is strong, resilient, and iridescent, and it has high fracture-resistance. Nacre is secreted by some mollusks, including pearl oyster shells and freshwater pearl mussels.
What is the formula for the protein conchiolin?

What is the function of conchiolin in shells?
Shells of molluscs also contain phosphorus (e.g., calcium phosphate), and the phosphorylated protein conchiolin is abundant in their soft tissues, playing a key role in the aggregation of minerals and organic compounds to produce shells (Cariolou & Morse, 1988).
What kind of scleroprotein is conchiolin made of?
They are composed of a complex scleroprotein named conchiolin and calcium carbonate in the form of aragonite and or calcite arranged in concentric layers.
What is the specific gravity of a conchiolin core?
The average figure is quoted as 2.71, while around 80% of all pearls do not reach a figure higher than 2.72. The figure may fall to 1.91 or even lower if a large inner conchiolin core is present, the specific gravity of conchiolin is quoted as 1.34.
