Globo-N-tetraose (CAS 75660-79-6)

Globo-N-tetraose is a tetrasaccharide that forms part of the structural framework in more complex glycosphingolipids known as globosides, which are abundant in human red blood cells and certain tissues. Structurally, it consists of a sequence of sugar molecules including glucose and galactose, which are complexly linked in a specific arrangement. This oligosaccharide is particularly significant in research related to blood group antigens, specifically the P blood group system, where it serves as a precursor for the synthesis of the Pk antigen. In the realm of scientific research, Globo-N-tetraose is utilized to explore the biosynthesis and function of glycosphingolipids within the cell membranes. Its role is crucial in understanding the mechanisms of cell recognition and adhesion, which are vital for cellular interactions and communication. Studies involving Globo-N-tetraose often focus on its biochemical synthesis and degradation, providing insights into the enzymatic pathways that regulate these processes. Additionally, researchers use this tetrasaccharide to investigate the genetic factors influencing the expression and variability of globosides, which can shed light on their roles in development and disease processes, particularly those related to cell membrane composition and function. Through such studies, Globo-N-tetraose contributes to a deeper understanding of glycolipid metabolism and its implications in cellular physiology and pathology.
