Molecular markers for marine algal polysaccharides
Alginate, carrageenan and agar are marine algal polysaccharides with several common features. They all contain linear substructures which enable them to form gels. All three types of polymers vary within and between samples in subunit composition and arrangement, and in molecular weight. That the subunit organization in these complex algal polymers is neither completely regular nor completely random is becoming increasingly clear (Larsen, 1981; Greer et al., 1984). The relationship between carbohydrate primary structure, polymer conformation and biochemical properties of marine algal carbohydrates is gaining increasing attention as new experimental approaches are being developed. Recent studies have involved combinations of chemical or enzymatic fragmentation; size, ionic or electrophoretic separations; and analysis of polymer properties or interactions by nuclear magnetic resonance spectroscopy, infrared spectroscopy, optical rotatory dispersion, circular dichroism, light scattering, calorimetry and other modern techniques (e.g., Dea et al., 1972; Larsen, 1981; Smidsrod & Grasdalen, 1984; Lahaye et al., 1985).
