Summary of "Single-Chain β-D-Glycopyranosylamides of Unsaturated Fatty Acids: Self-Assembly Properties and Applications to Artificial Cell Development."

Amphiphilic molecules undergo self-assembly in aqueous medium to yield various supramolecular structures depending on their chemical structure and molecular geometry. Among these, lamellar membrane bound vesicles are of special interest due to their resemblance to cellular membranes. Here, we describe the self-assembly of single-chain amide-linked amphiphiles derived from β-D-galactopyranosylamine and various unsaturated fatty acids into vesicles. Fluorescence spectroscopy, X-ray diffraction, and differential scanning calorimetry are used to determine various physical parameters pertinent to the self-assembly process. The vesicular architecture is characterized using optical microscopy and transmission electron microscopy. Moreover, we show that the vesicles derived from these amphiphiles can encapsulate molecules of various sizes and host model biochemical reactions. Our work demonstrates that single-chain glycolipid-based amphiphiles could serve as robust building blocks for artificial cells and have potential applications in drug delivery and microreactor design.

Medical and Biotech [MESH] Definitions

UNSATURATED FATTY ACIDS that contain at least one double bond in the trans configuration, which results in a greater bond angle than the cis configuration. This results in a more extended fatty acid chain similar to SATURATED FATTY ACIDS, with closer packing and reduced fluidity. HYDROGENATION of unsaturated fatty acids increases the trans content.

Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED). (Grant & Hackh's Chemical Dictionary, 5th ed)

An enzyme localized predominantly within the plasma membrane of lymphocytes. It catalyzes the transfer of long-chain fatty acids, preferentially unsaturated fatty acids, to lysophosphatides with the formation of 1,2-diacylglycero-3-phosphocholine and CoA. EC

FATTY ACIDS in which the carbon chain contains one or more double or triple carbon-carbon bonds.

A long-chain fatty acid ester of carnitine which facilitates the transfer of long-chain fatty acids from cytoplasm into mitochondria during the oxidation of fatty acids.
