Macroalgae or seaweed are relative un-explored and promising sources of novel
molecules for the food industry including peptides and carbohydrates for their use as
functional foods and nutraceuticals. Several algae-derived bioactive compounds have
shown a wide range of biological activities both in vitro and in vivo, i.e. antihypertensive
and antioxidant, that are strongly associated with the chemical structure of the
peptides or carbohydrates. Multiple improvements in the purification and analytical
tools to characterize these compounds have been reported in recent years, aiming to
gain further insight into the complexity of different molecular structures of bioactive
peptides and carbohydrates. This paper discusses the variable composition of algae
and the opportunities of the use of this biomass to obtain novel functional bioactive
peptides and carbohydrates for functional food applications. The main biological
activities of the discovered bioactive peptides and carbohydr...
