Abstract

Comparison of the ability of the enantiomeric forms of trehalose to stabilise alkaline phosphatase towards dehydration and heat showed that natural d-trehalose is superior to l-trehalose, although both disaccharides provide some protection for the enzyme. The result of this novel experiment suggests a chiral differentiation between carbohydrate and protein and thus lends support for the water replacement hypothesis of solute-based stabilisation of biomolecules, but the non-crystallinity and the physical form of the l-isomer may also be a key factor.
