The study further identified three distinct lifespan-promoting molecules from Root265, water-soluble polysaccharides (PSs), water-insoluble arabinogalactan peptidoglycan (AGP), and organic polar ...

Gram-positive cell walls have a thick peptidoglycan layer beyond the plasma membrane. Characteristic polymers called teichoic and lipoteichoic acids stick out above the peptidoglycan and it is because ...
