Heparin disaccharide III-A, sodium salt (CAS 136098-11-8)

Heparin disaccharide III-A, sodium salt, is a defined disaccharide derived from heparin and structurally composed of glucuronic acid and N-acetylglucosamine units, retaining specific sulfate modifications characteristic of the larger heparin glycosaminoglycan chains. This structural specificity makes it valuable in scientific research focusing on understanding heparin′s role in protein interactions, especially with coagulation factors like antithrombin, enzymes, and other heparin-binding proteins. The sodium salt form enhances solubility and stability, allowing researchers to precisely investigate these interactions in biochemical assays. This compound aids in elucidating the structure-activity relationships within heparin by highlighting the functional roles of sulfation patterns and saccharide sequence on protein binding and biological activities. Heparin disaccharide III-A, sodium salt, is particularly useful in studying the minimal structural motifs necessary for heparin′s anticoagulant activity. Researchers use it to dissect the complex mechanisms of heparin-protein interactions and the subsequent modulation of biological processes such as blood coagulation and cell signaling. Furthermore, the disaccharide′s clearly defined structure allows scientists to explore the effects of structural changes on affinity and specificity in protein binding. These insights contribute significantly to advancing our understanding of glycosaminoglycan biology, particularly heparin′s complex interactions and its critical functions within biological systems.
