origin of biological chirality?

A study has found that lipid membranes can be selectively permeable to one or the other sugar or amino acid enantiomer. The study used membrane models inspired by the membranes of modern organisms, so is not directly relevant to abiogenesis. However it still raises the possibility that membrane selectivity was the source of chirality in biological molecules. One possible issue is does this effect require chiral membrane lipids; if so it only move the question of the origin of chirality from sugars and amino acids to lipids.
