Collagen, gelatin and collagen hydrolysate were prepared from bovine limed split wastes by different preparative processes. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed that the molecular weight distribution of collagen was very narrow (about 200 and 100kDa for β and a chains respectively) compared with those of gelatin (less than 300kDa and wide distribution) and collagen hydrolysate (less than 50kDa and wide distribution ). The isoelectric points of…

Hydrolysed Collagen from Sheepskins as a Source of Functional Peptides with Antioxidant Activity
TLDR
Results suggest that HC could be a good alternative to replace HC from typical sources like pigs, cows and fish.
Partial Characterization of Fish Skin Collagen Cross-Linked by N-Hydroxysuccinimide Activated Adipic Acid
Fish skin collagen solutions (0.3%, w/v) were treated using N-hydroxysuccinimide activated adipic acid (NHS-AA) as a cross-linking agent. Partial important physicochemical properties such as the
Physicochemical properties of collagen solutions cross-linked by glutaraldehyde
TLDR
It was proved that the collagen solutions possessed strikingly different physicochemical properties depending on the amount of GTA, with a clear loss of flow and a sudden rise of the Td value compared to the uncross-linked collagen solution, probably illustrating thatThe collagen solution was converted into a gel with mature network structure-containing nuclei observed in AFM image.
