Mar 1, 2022 · Dextran is a nontoxic and biocompatible polysaccharide that has wide applications in pharmaceutical, biomedical, and industrial fields. The chapter provides an overview of these aspects apart from most significant developments in this field.
Dextran is a complex branched glucan (polysaccharide made of many glucose molecules). Dextran is synthetized from sucrose by certain lactic-acid bacteria, the best known are Leuconostoc bacteroides and Streptococcus mutans. When used as a component of colloid solutions, dextrans are mixed in normal saline as an isotonic solution.
Jul 1, 2021 · The aim of this review article is to compile the latest research (in the past decade) using LAB to synthesize high or low molecular weight dextran. In addition, studies using modified enzymes to produce dextran with specific structural characteristics (molecular weights and branches) are addressed.
Jan 21, 2023 · By virtue of its properties, DEX has been used for over 50 years as a circulatory volume expander, in order to improve blood flow [ 13] and prevent postoperative deep-vein thrombosis [ 16 ]. It has also been used in anaemia treatment or as an antiviral agent, being selective for various viruses [ 13 ].
Description. Dextran is a polysaccharide that differs from others in that its glucose units are joined together 1:6 glucoside links. The main chain of glucose has short branches at frequent intervals which are probably joined by 1:3 and 1:4 glucoside links. The chains can be composed of about 200,000 glucose units.
Dextran is a polysaccharide consisting of alpha-D-glucopyranosyl units, with varying degrees of chain length and branching. Dextran has been used as a polymer coating material owing of its biocompatibility. Dextran is known for its antithrombotic and blood viscosity reducing actions.
