Gorgonin

The skeleton of a bamboo coral; the darker joints are gorgonin nodes

Gorgonin is a flexible[1] scleroprotein[2] which provides structural strength to gorgonian corals, a subset of the order Alcyonacea.[3] Gorgonian corals have supporting skeletal axes[clarification needed] made of gorgonin and/or calcite.[4] Gorgonin makes up the joints of bamboo corals in the deep sea,[5] and forms the central internal skeleton of sea fans.[1] It frequently contains appreciable quantities of bromine, iodine, and tyrosine.[3]

Gorgonin is diagenetically stable and is deposited in discrete annual growth rings in Primnoa resedaeformis, and possibly other species.[6][7]
