Preparation, Purification, and Use of Fatty Acid-containing Liposomes

82.1K
Liposomes containing single-chain amphiphiles, particularly fatty acids, exhibit distinct properties compared to those containing diacylphospholipids due to the unique chemical properties of single chain amphiphiles. Here we describe techniques for the preparation, purification, and use of liposomes comprised in part or whole of these...

Identification of Fatty Acids in Bacillus cereus

10.1K
We propose a protocol to identify fatty acids without the need to purify them. It combines information on the retention times with the mass spectra of three types of fatty acid derivatives: fatty acid methyl esters (FAMEs), 4,4-dimethyl oxazoline derivatives (DMOX), and 3-pyridylcarbinyl esters (picolinyl).

Analysis of Fatty Acid Content and Composition in Microalgae

61.5K
A method for the determination of fatty acid content and composition in microalgae based on mechanical cell disruption, solvent based lipid extraction, transesterification, and quantification and identification of fatty acids using gas chromatography is described. A tripentadecanoin internal standard is used to compensate for the possible losses during extraction and incomplete...

Optimized Incorporation of Alkynyl Fatty Acid Analogs for the Detection of Fatty Acylated Proteins using Click Chemistry

6.0K
The study of fatty acylation has important implications in cellular protein interactions and diseases. Presented here is a modified protocol to improve click chemistry detection of fatty acylated proteins, which can be applied in various cell types and combined with other assays, including pulse-chase and mass...

Saturated Fatty Acids Induce Ceramide-associated Macrophage Cell Death

9.6K
We illustrate a straight-forward method to derive murine primary macrophages from bone marrow cells and a simple method to prepare BSA-fatty acid conjugates. Then we demonstrate that saturated fatty acids can induce macrophage cell death, and such cell death is positively associated with cellular accumulation of ceramide...

Area of Science:

  • Entomology
  • Biochemistry
  • Chemical Ecology

Background:

  • Insects extensively use pheromones for various behaviors, including mating and aggregation.
  • A significant portion of insect pheromones are biosynthesized from fatty acid precursors.
  • Understanding these biosynthetic pathways is key to insect communication research.

Purpose of the Study:

  • To provide detailed examples of studied biosynthetic pathways for fatty acid-derived pheromones.
  • To examine pheromone biosynthesis in key insect orders: Lepidoptera, Coleoptera, and Hymenoptera.
  • To briefly discuss the biosynthesis of hydrocarbon-based pheromones.

Main Methods:

  • Literature review and synthesis of existing research on insect pheromone biosynthesis.
  • Focus on pathways involving fatty acids as precursors.
  • Comparative analysis across different insect orders.

Main Results:

  • Detailed examples of fatty acid-derived pheromone biosynthesis in Lepidoptera, Coleoptera, and Hymenoptera are presented.
  • Lepidopteran species commonly use fatty acids to produce aldehydes, alcohols, and acetate esters as pheromones.
  • Biosynthesis of hydrocarbons and modified hydrocarbons as pheromones is also briefly covered.

Conclusions:

  • Fatty acid metabolism is a central theme in the biosynthesis of diverse insect pheromones.
  • The studied pathways highlight conserved and divergent mechanisms across insect orders.
  • Further research into these pathways can inform pest management and ecological studies.
