Palmitelaidic acid is primarily used in research settings to study the effects of trans fats on biological systems. It serves as a model compound to understand the impact of trans fatty acids on cellular processes, particularly in relation to lipid metabolism and cardiovascular health. Researchers utilize it to investigate how trans fats influence membrane fluidity, enzyme activity, and signaling pathways. Additionally, it is employed in the development of analytical methods for detecting and quantifying trans fats in food products, aiding in nutritional studies and food safety assessments. Its role in these studies contributes to a better understanding of the health risks associated with trans fat consumption.
