Abstract(s)
A crescente preocupação da população em geral com a saúde e bem-estar incentiva a indústria a apostar em produtos que se revelam benéficos na prevenção e/ou tratamento de doenças.
A natureza tem sido desde sempre a maior fonte de moléculas com atividades biológicas interessantes. Nos últimos anos tem vindo a crescer o interesse pelo estudo dos compostos obtidos de organismos marinhos, nomeadamente as macroalgas.
As macroalgas são um grupo muito heterogéneo que pode ser subdivido em três grupos distintos de acordo com a pigmentação que apresentam. As macroalgas castanhas por possuírem compostos exclusivos são estudadas intensivamente. Com um elevado valor nutritivo, mas de um baixo teor calórico, as macroalgas castanhas apresentam na sua constituição, entre outros compostos, metabolitos secundários biologicamente ativos nomeadamente polifenóis, que além de conferirem proteção às macroalgas ainda apresentam, entre outras, propriedades antioxidantes e anti-inflamatórias que podem ser incorporados em nutracêuticos.
Com o desenvolvimento deste trabalho, pretende-se analisar as propriedades biológicas de diversos compostos extraídos das macroalgas castanhas e os seus possíveis benefícios na incorporação dos mesmos em nutracêuticos.

In recent years there has been growing interest in the study of compounds of marine organisms, such as macroalgae. Macroalgae are a very heterogeneous group that can be subdivided into three distinct groups according to a pigmentation it presents. As brown macroalgae because they have a way of getting free are intensively studied. With a high nutritional value, but with low caloric content, such as brown macroalgae, among others, metabolites that are biologically active are polyphenols, which also confer the guarantee to macroalgae still present, among others, antioxidant and anti-oxidant properties that can be incorporated into nutraceuticals. In order to carry out the work, we intend to analyze the biological characteristics of the compounds extracted from the macroalgae and to allow the incorporation of the same in nutraceuticals.
