The world’s oceans, which cover more than 70% of the Earth’s surface, represent an enormous source of potential therapeutic agents. During the last few decades, numerous novel compounds have been found from marine organisms with interesting pharmaceutical activities. Therefore, marine organisms are believed to be a potential source of not only novel biologically active substances that aid in the development of pharmaceuticals but also compounds essential to human nutrition (Blunt et al. 2006; Vo and Kim 2010). In particular, marine peptides have attracted a great deal of attention due to their potential effects in promoting health and reducing disease risk.
