Life on Earth uses exclusively L-amino acids and D-sugars, a property known as biological homochirality. Yet, the origin of this molecular asymmetry remains a fundamental mystery in prebiotic chemistry. This study investigates whether modern enzymes retain signs of evolutionary preference for one enantiomer, using alkaline phosphatase (ALP) as a model. write an illustration for this See more
