The disclosed subject matter, in one aspect, relates to compounds and compositions {e.g., polysaccharides and polysaccharide complexes) and methods for providing and using such compounds and compositions. Disclosed are compositions comprising a polysaccharide or polysaccharide complex obtained from Chlorella, wherein the polysaccharide or polysaccharide complex has a molecular weight of from about 1 x 103 to about 1 x 106 Da. Also disclosed are methods of providing a polysaccharide or polysaccharide complex, comprising the steps of providing a Chlorella extract, contacting the extract with a solvent to provide a precipitate, contacting the precipitate with additional substances {e.g., a surfactant) and isolating an insoluble fraction, and size fractioning the insoluble fraction, thereby providing the polysaccharide or polysaccharide complex. Disclosed are also methods for using the disclosed polysaccharide and polysaccharide compositions.
