Sulfation patterns and the amounts of chondroitin sulfate in the diamond squid, Thysanoteuthis rhombus

Abstract

We determined the sulfation patterns and the amount of chondroitin sulfate in several tissues of the diamond squid, Thysanoteuthis rhombus. Every tissue contained the highly-sulfated E type of chondroitin. The arms, skin, and fin had non-sulfated chondroitin as the homogenous polymer. The skin and fin possessed larger amounts of chondroitin sulfate per unit of weight than the other tissues.
