WebApr 14, 2024 · The lipid and fatty acid compositions of the feed and fish liver were analyzed using thin-layer and high-performance liquid chromatography. The viability, size, and biochemical indices of the fish responded to the growth physiology, environmental variables such as the dissolved oxygen content and water temperature, and sporadic factors. WebWe present recently developed strategies to manipulate lipid levels in live cells by light. We focus on photoremovable protecting groups that lead to subcellular restricted localization …
WebPhotoliberation of native lipid species from caged lipids constitutes the most straightforward experimental approach to induce well-defined, temporally controlled density increases of a single lipid species in individual membrane leaflets (23–25), which is essential for kinetic analysis (Fig. 1A). In order to study WebJun 1, 2024 · Deprotection of the Fmoc and Fm groups in one step afforded the desired caged lipids 19 a and 19 b. Both were alkylated with acetoxymethyl bromide to give the bioactivatable caged lipid derivatives 1 a and 1 b, respectively. In the case of PI(3,4)P 2 deprotection, a fraction of the molecules lost the coumarin group.
WebWe focus on photoremovable protecting groups that lead to subcellular restricted localization and activation and discuss alternative techniques. We emphasize the development of organelle targeting of caged lipids and discuss recent advances in chromatic orthogonality of caging groups for future applications. KW - Fluorescence.
