Digalactosyldiacylglycerol 

Digalactosyldiacylglycerol is a membrane structure stabilizer that selectively acts on photosystem II light-harvesting complex II (LHCII), serving as a natural bilayer-forming lipid in plant thylakoid membranes. Digalactosyldiacylglycerol constructs a lipid bilayer environment with monogalactosyldiacylglycerol (MGDG) in a 2:1 molar ratio, stabilizing the supramolecular structure of LHCII through interactions such as hydrogen bonding. Its core activity is maintaining thylakoid membrane stacking (grana formation) and supporting photosynthesis-related functions, while also possessing functions in light harvesting assistance and excitation energy quenching regulation under light stress. Digalactosyldiacylglycerol can be used in research on plant photosynthesis mechanisms, thylakoid membrane structure and function regulation, as well as in the construction of artificial photosynthetic systems and the development of plant photoprotection strategies^[1].
