Lipid classes of selected anatomical structures from the portuguese man-of-war Physalia physalis

Abstract

1. 1. The total lipids and principal lipid classes of six distinct anatomical portions of Physalia physalis were determined. 2. 2. The principal total body store of lipids was in the gastrozooids. 3. 3. Cholesterol accounted for 4% of the dry weight of the saccus and 2% of the gas gland. 4. 4. Although present at a very low level, cholesterol was detected in the gastrovascular fluid for the first time.
