Acid-Pepsin Soluble Collagen from Saltwater and Freshwater Fish Scales

Modified Lowry’s Method for Acid and Pepsin Soluble Collagen Measurement from Clarias Species Muscles

Collagen is the most abundant animal protein polymer, accounting for almost 25 to 30% of total protein in animal body [1,2]. Being one of the extracellular matrix constituents of multi-cellular animals [3], it can be found in connective tissues and served as major component of bones, cartilage, skin, tendons, ligaments, blood vessels, muscles, teeth and other organs of vertebrate [4,5]. Studies...

Fish intake and serum fatty acid profiles from freshwater fish.

BACKGROUND Although high mercury concentrations in fish diets raise an alarm, fish can also be a healthy choice because it is the primary source of n-3 fatty acids (FAs). However, little information is available on the contribution of freshwater fish to serum FA concentrations. OBJECTIVE This study examined the FA pathway from fish to serum in 243 moderate consumers of freshwater fish. DESI...

physico-biochemical characteristics of scallop mantle collagen soluble in pepsin

collagen, which is widely distributed in pluricellular animals, is one of the most fundamental constituents of the extracellular matrix, and plays mechanically or physiologically important roles in their bodies. in this study, the biochemical and physical characteristics of pepsin-solubilized collagen from the mantle of yesso scallop (ympc), a by-product of processing, was determined. electroph...

Iron Reduction in Freshwater and Saltwater Environments

Isolation and characterization of acid-soluble collagen from the skin of Rutilus Frisii Kutum (Kamensky) of the Caspian Sea

This study proceeds to extract collagen from the skin of Rutilus  kutum, one of  the main and economical species of the Caspian Sea. Acid-soluble collagen (ASC) from the skin of R. kutum was extracted and characterized by SDS-PAGE, FTIR and UV spectrophotometry. Based on the data from the SDS-PAGE and the composition of amino acid, it was probable that the obtained collagen classified as type I...
