The bacterioruberin [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/22B], C50 H76 O4, is a 50 carbon carotenoid pigment which give a red color to the membrane . The primary role of bacterioruberin in the cell is to protect against DNA damage incurred by UV light. This protection is not, however, due to the ability of bacterioruberin to absorb UV light. Bacterioruberin protects the DNA by acting as an antioxidant, rather than directly blocking UV light. It is able to protect the cell from reactive oxygen species produced from exposure to UV by acting as a target. | The bacterioruberin [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/22B], C50 H76 O4, is a 50 carbon carotenoid pigment which give a red color to the membrane .

The 2,3-di-phytanyl-glycerol [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/L2P], C43 H88 O3, is an archaeol (di-O-phytanylglycerol). This is a double ether of sn-1-glycerol where positions 2 and 3 are bound to phytanyl residues.The archaeols are Archaea homologs of diacylglycerols (DAGs). | The 2,3-di-phytanyl-glycerol [http://www.ebi.ac.uk/pdbe-srv/pdbechem/chemicalCompound/show/L2P], C43 H88 O3, is an archaeol (di-O-phytanylglycerol).
