K. Arakawa et al., TIGHTLY PACKED MEMBRANES COMPOSED OF 36-MEMBERED MACROCYCLIC DIETHER PHOSPHOLIPID FOUND IN ARCHAEA GROWING UNDER DEEP-SEA HYDROTHERMAL VENTS, Chemistry Letters, (9), 1998, pp. 901-902
We were the first to investigate the properties of the archaeal 36-mem
bered macrocyclic diether phospholipid 1a in comparison with the corre
sponding acyclic counterpart 2a. Results from thermal analyses and mon
olayer studies indicated that the 36-membered macrocyclic diether lipi
d can aggregate to more tightly packed structures than the acyclic con
gener due to less motional freedom at the alkyl chain region.
