Ionophores, Channels, Transfer Proteins, and Storage Proteins

Part of the Biochemistry of the Elements book series (BOTE, volume 7)


Cells must selectively absorb nutrients, including inorganic ones; indiscriminate absorption would seriously jeopardize their well-being. The general chemical principles of selective uptake were discussed in the previous chapter. In the present chapter we concentrate on some of the more concrete aspects of passive uptake including the role of ionophores (and scavengers), channels, (serum) transfer proteins, and storage proteins. The first two concepts are associated with the transport problems across the membrane, whereas the latter two involve specific proteins that bind inorganic elements in the cytoplasm and in blood serum or are used to store inorganic chemicals.
