Abstract
1. The synthesis of proteins, glycoproteins and sulfated macromolecules increase after hatching of the gastropod Concholepas concholepas larvae. 2. Sulfate present in the sea-water, stimulates over 30-fold the sulfation of sulfated macromolecules but not the proteins. 3. Analysis of the sulfated macromolecules indicates that almost 90% are localized in the larval insoluble material, corresponding to a high molecular weight macromolecule, probably a proteoglycan.
