vanadocytes造句

• The vanabins extracted from tunicate vanadocytes are often called hemovanadins.
• Vanabins are found almost exclusively in the blood cells, or vanadocytes of some ascidians and tunicates ( sea squirts ).
• In some species of Ascidiidae and Perophoridae, it contains high concentrations of the transitional metal vanadium and vanadium-associated proteins in vacuoles in blood cells known as vanadocytes.
• The vanadocytes are later deposited just below the outer surface of the tunic, where their presence is thought to deter predation, although it is unclear whether this is due to the presence of the heavy metal or low pH . Other species of tunicates concentrate lithium, iron, niobium, and tantalum, which may serve a similar function.
