dc.description.abstract In the pioneering and systematic study presented here, infrared spectroscopy was used to identify some of the chemical constituents of selected South African red (Rhodophyta), brown (Phaeophyta) and green seaweeds (Chlorophyta). The techniques used were KBr pellet, infrared microscope and diffuse reflectance Fourier transform spectroscopy. The main constituents of the red algae were found to be agar, carrageenans, cellulose and protein. The brown kelp seaweeds contain mainly alginates, cellulose and protein. The green seaweeds contain a considerable amount of protein, as well as cellulose and starch. The crystal habit of calcium carbonate present in calcified seaweeds was determined and the findings throw light on the study of the deposition process. It is shown that the differences in the chemical composition of the seaweeds are reflected in their infrared spectra. This fact may prove useful for taxonomic classification purposes. en
