1-18:3-2-18:3-Digalactosyldiacylglycerol (Cat No.:R074646) is a glycolipid composed of a glycerol backbone esterified with two linolenic acid (18:3) chains and a digalactose headgroup. It is a major component of plant chloroplast membranes, particularly in thylakoid structures, playing a critical role in photosynthesis and membrane stability. Its polyunsaturated fatty acid chains contribute to membrane fluidity and adaptability under stress conditions. DGDG is also studied for its bioactive properties, including anti-inflammatory and immunomodulatory effects. It is typically used in plant biology and lipidomics research under controlled laboratory conditions with appropriate lipid-handling procedures.
