Physicochemical And Structural Properties

The review covers recent literature on the ocean as both a source of biotechnological tools and as a source of bio-inspired materials. The emphasis is on marine biomacromolecules namely hyaluronic acid, chitin and chitosan, peptides, collagen, enzymes, polysaccharides from algae, and secondary metabolites like mycosporines. Their specific biological, physicochemical and structural properties together with relevant applications in biocomposite materials have been included. Additionally, it refers to the marine organisms as source of inspiration for the design and development of sustainable and functional (bio)materials. Marine biological functions that mimic reef fish mucus, marine adhesives and structural colouration are explained.

AbstractHyaluronic acid (HA) is widely distributed in the human body, and it is heavily involved in many physiological functions such as tissue hydration, wound repair, and cell migration. In recent years, HA and its derivatives have been widely used as advanced bioactive polymers for bone regeneration. Many medical products containing HA have been developed because this natural polymer has been proven to be nontoxic, noninflammatory, biodegradable, and biocompatible. Moreover, HA-based composite scaffolds have shown good potential for promoting osteogenesis and mineralization. Recently, many HA-based biomaterials have been fabricated for bone regeneration by combining with electrospinning and 3D printing technology. In this review, the polymer structures, processing, properties, and applications in bone tissue engineering are summarized. The challenges and prospects of HA polymers are also discussed.

Additional Value

Insects or products derived from insects are considered as a valuable feed ingredient for aquaculture, poultry, and pigs but also exert possible secondary effects of health stimulators in livestock as reported in literature. Health benefits attributed to insects can create additional value in the insect chain. Three categories of bioactive compounds in insects are reported in this desk study: antimicrobial peptides (such as α-helical peptides, cysteine-rich peptides, proline-rich peptides, glycine-rich peptides), fatty acids (especially lauric acid), and polysaccharides (especially chitin and chitosan). The review summarises the recent literature on these three categories. Antimicrobial properties or immuno-modulating effects may contribute to reduce the use of antibiotics and to avoid antibiotic resistance in livestock when these insect products are included in animal diets. Furthermore, antioxidant capacity of insect-proteins might reduce collateral tissue damage. Health stimulating effects of insect products may result in additional applications of insect products in animal feed for livestock.
