1 Introduction Fatty acids are fundamental constituents of biological membranes, where they are incorporated predominantly into phospholipids and other complex lipids that determine membrane architecture, biophysical properties, and cellular function.

1 Introduction Chirality represents a fundamental structural property of biological molecules in which two configurations exist as non-superimposable mirror images known as enantiomers. In living systems, this stereochemical asymmetry is expressed as biological homochirality, a universal characteristic whereby proteins are constructed almost exclusively from l-amino acids while nucleic acids contain d-ribose or deoxyribose sugars in their phosphate backbones.
