Phospholipid analogs and beyond: pleiotropic roles of betaine lipids in phycology, ecology, and biomedicine.

Betaine lipids (BLs) exhibit diverse functions beyond phosphate starvation adaptation, including roles in fatty acid metabolism, environmental stress response, and ecological interactions.

• Why it matters: Understanding the full range of BL functions is important because it reveals their significance in microalgal physiology, ecology, and potential biomedical applications, addressing gaps in current knowledge.
• What they did: The review summarizes recent research on BLs' pleiotropic roles in microalgae, fungi, bacteria, mosses, and ferns, emphasizing their involvement in stress adaptation, ecological interactions, and bioactive functions in mammals.
• The result: These findings suggest BLs have multifunctional roles that extend beyond phosphate substitution, opening new avenues for ecological, biotechnological, and biomedical exploration.
