Marine organisms have long been recognized as rich source of bioactive material with numerous health benefit effects. Among bioactive material, proteins and peptides derived from marine organisms have been shown to inhibit the development of neuro-degenerative diseases such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis. The neuro-protective action of protein and peptide seem to be mediated through direct interaction of absorb protein and peptide with a numerous of cellular and molecular targets with enzyme/ion channels. This contribution presents an overview of marine proteins and peptides neuro-protective effect and their potential application in neuro-protection.
