Calcium Carbide: My teachers are wondering whether there are any restrictions on us storing and using Calcium carbide for pracs here at school? They apparently used to do some wonderful pracs with it in the past, which they have not done for many years
Calcium activates Fpn-mediated iron efflux We considered the hypothesis that Fpn functions as an iron/ion antiporter. Metal transport by both BbFpn and human Fpn was previously shown to be pH
