Information technology : The configuration at C10‐OH of the caminoside aglycone (see formula) was shown to be R by interpretation of exciton coupling in the circular dichroism (CD) spectrum of the tetraphenylporphyrin carboxylate diester of (2 R ,10 R )‐2,10‐nonadecanediol. This compound is derived from the title compound and was embedded in highly uniform nanometric liposomes for the CD measurements.
