Purpose of the Lipid Quantification Calculator
The core purpose of the Lipid Quantification Calculator is to deliver a robust, accessible platform for computing lipid concentrations via spectrophotometry, rooted in the Beer-Lambert Law: A = ε × c × l. This equation, validated through decades of peer-reviewed research, relates absorbance (A) to concentration (c), extinction coefficient (ε), and path length (l). By automating these calculations, the tool facilitates accurate quantification of phospholipids, triglycerides, and other lipids, aiding in the elucidation of biological processes. It serves as a bridge between raw experimental data and interpretable results, promoting scientific rigor.
Scientific Basis of the Calculator
Founded on the Beer-Lambert Law, a cornerstone of analytical chemistry, the Lipid Quantification Calculator employs the formula c = A / (ε × l) to derive molar concentrations. This law assumes monochromatic light and dilute solutions, conditions met in standard lipid assays like the Folch method combined with colorimetric detection. Peer-reviewed studies, including those in the Journal of Lipid Research, confirm the law's applicability to lipid quantification, ensuring the tool's outputs align with experimental standards. Users can adjust ε based on specific dyes or lipids for customized accuracy.
