Sterol composition was determined in snow crab hepatopancreas and mackerel and herring viscera for various locations and collection periods. A simple and valuable method, using direct saponification and extraction with water-cyclohexane has been optimized to recover total sterol. They were identified and quantified as trimethylsilyl ether derivatives by(More)
Sequential acidic precipitation followed by a single chromatographic step (gel filtration) allowed the recovery of a collagenolytic fraction containing several proteases from by-products of snow crab (Chionoecetes opilio). The partial purification was particularly efficient to recover tryptic (purification fold = 1,352.5; yield = 110%) but also(More)
