Collagen is a general term to define a group of structural proteins of the extracellular matrix, organized in a fibrillar arrangement. Collagen is the main component of connective tissue (e.g. in cartilage, bones, tendons, ligaments, and skin). Collagens are the most abundant high molecular weight proteins in both invertebrate and vertebrate organisms, including mammals and fish. Collagen consists of amino acids bound together in a triple helix. Depending upon the degree of mineralization, collagen tissues may be rigid (bone), compliant (tendon), or have a gradient from rigid to compliant (cartilage). Bovine collagen is of Type I and Type III while fish collagen is composed of collage Type I.
Gelatin is the partially hydrolysed form of collagen and consists of a mixture of peptides and proteins.
Fish oil is a major source of the omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which play an important role in regulating body functions and health
Tunicates are a group of sea invertebrates known as the only animals to produce cellulose. The name "tunicates" is derived from their outer covering, which is referred to as a tunic. Ascidians are the major group of tunicates, found mostly on hard surfaces, such as rocks, and include the filter feeding animal Ciona intestinalis.
