Collagen is the most studied protein with a wide range of applications including pharmaceutical, biomedical, cosmetics, leather, and film industries due to its special characteristics that are high biocompatibility, good bioactivity, and weak antigenicity. Although collagen sources are abundant, the outbreak of varied diseases among land animals posed threat to its utilization in our daily life. Thus, a probe for an alternative source began, which in turn revealed the immense untapped marine sources, such as fish, jellyfish, and some marine Mammals. The present article deals with a brief description of collagen, its characteristics, marine sources, extraction, collagen peptides and their biological activities, potential use and application in various field.
Keywords: application; bioactivity; collagen; marine source; peptides.
