Inositol Phosphoglycan

Meaning

Inositol Phosphoglycan (IPG) refers to a class of complex carbohydrate-containing molecules proposed to function as critical secondary messengers in cellular signaling pathways, particularly those activated by insulin and other peptide hormones. These molecules are generated from the hydrolysis of glycosylphosphatidylinositol (GPI) anchors on the cell membrane surface. IPGs are thought to modulate the activity of key intracellular enzymes involved in glucose and lipid metabolism, serving as a crucial link between the external hormonal signal and the internal metabolic response. While their exact structure and universal function are still under active investigation, they are central to the current understanding of insulin action and resistance.
