Studies on complex lipids. Synthesis of ionophoric derivatives of diphosphatidylglycerol (cardiolipin) was written by Kuz’mina, Yu. V.;Kaplun, A. P.;Shvets, V. I.;Saenko, V. A.;Egorova, E. M.. And the article was included in Bioorganicheskaya Khimiya in 1988.Formula: C13H24O4 This article mentions the following:
Synthesis of cardiolipin analogs containing a dibenzo-18-crown-6 ionophore residue in the fatty acid moiety, e.g. I (R = fatty acid residue), is described. The ionophore is incorporated into the second position of the glycerol residue by acylating mono- and dilysocardiolipin with a modified fatty acid anhydride. Lyso derivatives of cardiolipin have been prepared by enzymic hydrolysis of beef heart cardiolipin by snake venom phospholipase A2. In the experiment, the researchers used many compounds, for example, 12-Methoxy-12-oxododecanoic acid (cas: 3903-40-0Formula: C13H24O4).
12-Methoxy-12-oxododecanoic acid (cas: 3903-40-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
