Ab initio modeling of protein/biomaterial interactions: competitive adsorption between glycine and water onto hydroxyapatite surfaces.
Both glycine and water exhibit a high affinity towards the hydroxyapatite HA surfaces. What happens when they are co-adsorbed at the HA (001) surface? B3LYP periodic calculations reveal that glycine displaces the pre-adsorbed water interacting directly with the HA surface.
