For improvinghealth care products and drugs for the prevention and treatment of metabolicdiseases lay the foundation and providing important basis, research anddevelopment of marine biological products in view of the unknown mechanism andpoor effect of seaweed polysaccharide in the prevention and treatment ofmetabolic syndrome will be demonstrated. The research and development of marinebiological products comprehensively uses the technology of macrogenomics,molecular biology, metabonomics and pharmacology to study the functionmechanism of intestinal bacteria polysaccharide lyase in the prevention andtreatment of metabolic syndrome by seaweed polysaccharide. Establishing thepolysaccharide lyase and low molecular weight seaweed polysaccharide libraryand developing a new type of seaweed polysaccharide library will be carriedout.
