An Overview of Multifaceted Applications and the Future Prospects of Glyceroglycolipids in Plants

Glyceroglycolipids (GGLs) are a class of lipid molecules that contain a glycerol backbone and one or more carbohydrate moieties, giving them amphipathic properties with both hydrophilic and hydrophobic regions. This amphipathic nature is fundamental for composing cell membrane lipid bilayers. These compounds are primarily distributed on the inner chloroplast membranes of plants and exhibit a unique structure with numerous biological activities. Moreover, GGLs play a pivotal role in photosynthesis and energy conversion in plants and effectively respond to environmental stressors. This Review discusses the distribution, synthesis pathways, and functions of GGLs in plants and describes the recent updates on various methods for extracting, isolating, and identifying GGLs. Finally, this Review discusses the biological activities of plant GGLs, including their anti-inflammatory, antiviral, and anticancer properties, and highlights their potential applications in the fields of pharmaceuticals, food, and cosmetics. This Review provides insights into GGLs, offering research support for the application of these natural molecules in the realm of holistic health.
