Alginate is an acidic polysaccharide mainly extracted from kelp or sargassum, which comprises 40% of the dry weight algae. It a linear polymer consisting β-D-mannuronic acid (M) and α-L-guluronic (G) with 1,4-glycosidic linkages, possessing various applications in food nutraceutical industries due to its unique physicochemical properties health benefits. Additionally, alginate able form gel matrix presence Ca2+ ions. also affect gelation, including structure experimental conditions such as pH, temperature, crosslinker concentration, residence time ionic strength. These features this have been widely used industry, gels, controlled-release systems film packaging. This review comprehensively covers analysis discussed potential industry nutraceuticals.

Alginate lyases can fully degrade alginate into various size-defined unsaturated oligosaccharide products by β -elimination. Here, we identified the bifunctional endolytic lyase Aly35 from marine bacterium Vibrio sp. Strain H204. The enzyme is classified polysaccharide 7 superfamily and contains two catalytic domains. relationship function of domains are not well known. Thus, full-length recombinant its truncated proteins Aly35-CD1 (catalytic domain 1), Aly35-CD2 2 domain) were constructed. three enzymes showed similar biochemical characteristics exhibited temperature pH stability. Further research that efficiently alginate, polymannuronate (PM) polyguluronate (PG) a series oligosaccharides, while exhibits greater PM-degrading activity than but degraded PG efficiently. results suggest (Trp 295 -His 582 ) critical for PG-degrading activity, has (Leu 53 -Lys 286 higher both together confer increased (including M-blocks G blocks)-degrading activity. truncations will be useful tools structural analyses preparing bioactive especially used to prepare unit–rich oligosaccharides alginate.

Natural bone tissue has the certain function of self-regeneration and repair, but it is difficult to repair large damage. Recently, although autologous grafting "gold standard" for improving high cost, few donor sources. Besides, allogeneic causes greater immune reactions, which hardly meet clinical needs. The engineering (BTE) been developed promote repair. Gelatin, due its biocompatibility, receives a great deal attention in BTE research field. However, disadvantages natural gelatin are poor mechanical properties single structural property. With development BTE, often used combination with range natural, synthetic polymers, inorganic materials achieve synergistic effects complex physiological process review delves into fundamental structure unique gelatin, as well excellent necessary scaffold materials. Then this explores application modified three-dimensional (3D) scaffolds various structures including 3D fiber scaffolds, hydrogels, nanoparticles. In addition, focuses on efficacy composite consisting or polymeric materials, bioactive ceramics metallic/non-metallic defects. these gelatin-based provides new ideas design good biosafety.

Abstract Seaweed polysaccharides are natural biomacromolecules with unique physicochemical properties (e.g., good gelling, emulsifying, and film‐forming properties) diverse biological activities anticoagulant, antioxidant, immunoregulatory, antitumor effects). Furthermore, they nontoxic, biocompatible biodegradable, abundant in resources. Therefore, have been widely utilized food, cosmetics, pharmaceutical industries. However, their bioactivities sometimes not satisfactory for some purposes. Modification of can impart the amphiphilicity new functions to biopolymers change structure conformation, thus effectively improving functional so as meet requirement targeted applications. This review outlined modification methods representative red algae (carrageenan agar), brown (fucoidan, alginate, laminaran), green (ulvan) that potential food applications, including etherification, esterification, degradation, sulfation, phosphorylation, selenylation, on. The improved modified seaweed applications also summarized.
