“…[Ca 2+ ] did not have an obvious influence on the radical scavenging rate of these two collagen peptides, which corresponded with the reducing power trend. The antioxidants of GBB‐10SP and TYPE‐S were more significant than some special collagen and its peptide (Wen et al, ; Wu et al, ).…”

Empirical evidence proves that the antioxidant property plays a main role in the biological activities of biomaterials, which is influenced by several factors. In order to explore in‐depth, the influence of ionic systems on the antioxidant activity of collagen peptides was studied. Type‐I‐collagen peptides (GBB‐10SP and TYPE‐S) contained a high amount of hydrophobic amino acids and possessed good antioxidant activity at high concentrations in water. On the other hand, increasing [H+] and [Na+] concentrations (0.1 M to 0.5 M) decreased the reducing power of GBB‐10SP and TYPE‐S; however, [Ca2+] had no effect on the reducing power. Interestingly, the hydroxyl radical scavenging rate of these two peptides was increased by [Na+], decreased by [H+], and [Ca2+] had no effect. In general, TYPE‐S showed better antioxidant properties than GBB‐10SP. Overall, the above results confirmed that the antioxidant capacity of collagen peptides was affected by [H+] and [Na+] and not by [Ca2+]. Practical applications The present study mainly deals with the influence of ions on the antioxidant properties of collagen peptides. Recently, fish collagen peptides have been widely used as food supplements to cure several disorders and maintain normal physiological health in humans. It is noted that the use of collagen from fish processing wastes has brought several potential benefits including low value‐added products, preventing environmental pollution, and disease transmission by mammalian‐based collagen. But the biological activity of this peptide varied based on the preparation and its biochemical compositions. Here, we are reporting how to improve the biological activity of collagen, and also the factors affecting the antioxidant properties in order to avoid the down‐regulating mechanism. This study concluded that the [H+] and [Na+] influenced the antioxidant properties of collagen peptides, but [Ca2+] had not effect on the antioxidant properties.

“…Additionally, new uses for TGM in the field of novel biomaterials are suggested and can be generated via site-specific substrate binding by proteins modified by TGM [159,160]. Regarding different feedstocks, TGM has shown to improve the physical properties of fish feed, while, in cosmetics, the TGM-catalyzed reactions between amino groups of starch and γ-carboxamide groups of collagen peptides were investigated and reported to increase the effectiveness of some synthesized materials, such as drugs [156,161,162].…”

Stabilization and reusability of enzyme transglutaminase (TGM) are important goals for the enzymatic process since immobilizing TGM plays an important role in different technologies and industries. TGM can be used in many applications. In the food industry, it plays a role as a protein-modifying enzyme, while, in biotechnology and pharmaceutical applications, it is used in mediated bioconjugation due to its extraordinary crosslinking ability. TGMs (EC 2.3.2.13) are enzymes that catalyze the formation of a covalent bond between a free amino group of protein-bound or peptide-bound lysine, which acts as an acyl acceptor, and the γ-carboxamide group of protein-bound or peptide-bound glutamine, which acts as an acyl donor. This results in the modification of proteins through either intramolecular or intermolecular crosslinking, which improves the use of the respective proteins significantly.

Natural polymers, such as polysaccharides and proteins, have been widely studied for numerous biomedical applications because of their bioactivity, natural origin, and biodegradability. To address the different needs of a broad spectrum of biomedical applications, natural polymers are modified with or conjugated to small molecular compounds, synthetic and natural polymers, and inorganic nanomaterials and surfaces. Among these hybrid materials, polysaccharide–peptide conjugates have drawn much attention due to their design flexibility, biocompatibility, tunable degradability, and structure similarity to naturally occurring glycoproteins. In the past 20 years, polysaccharide–peptide conjugates have demonstrated the promising potential to address many long‐standing medical challenges. Thus, the design, conjugation chemistry and method, and biomedical applications of polysaccharide–peptide conjugates are summarized and discussed in this review. The conjugation techniques are reviewed from the view of the chemical reactions. Meanwhile, some inspiring examples of polysaccharide–peptide conjugates in biomedical applications, including drug delivery systems, nucleic acid delivery carriers, tissue engineering, and antimicrobial applications, are highlighted. Moreover, the outlook on the challenges and demands of polysaccharide–peptide conjugates is also elaborated.
