Natural sources, like seaweeds, are rich in effective anticancer molecules. Dietary consumption of seaweeds was reported to extensively reduce the occurrence of carcinogenesis (Sheu, Huang, & Duh, 1996). In the last few decades, many studies have focused on seaweeds and their benefits. The major component of seaweeds includes carbohydrates and proteins while other minor components like minerals and vitamins are also present in it. Polysaccharides from seaweeds are known to possess various biological activities, for example, effects on cancer cells and immune system (Yoshizawa et al., 1995). Thus, seaweeds are gaining much attention in the field of research with a main emphasis on seaweed polysaccharides and proteins as they are known to possess high therapeutic value in the field of nutrition or medicine. Our interest to study about seaweed glycoproteins was due to the above-mentioned reasons.
