how do u define bioactive molecules?
Bioactive molecules are substance that can be acted upon by a living organism or by an extract from a living organism. These molecules especially glycosaminoglycans(a polysaccharides) have therapeutic potential. They can be extracted from microorganism ,marine organism etc these can be used as anti-cancer. Bioactives molecules are the secondary metabolite (as organic compounds formed as bio products in organisms, not directly related to growth, development and normal reproduction of thereof) of an living organism especially microbes. Seaweeds are recognized as one of the richest sources of new bioactive compounds because survive in extreme conditions provides an enormous potential for the production of unique compounds.
