GO:0015878:   biotin transport
The directed movement of biotin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Biotin is cis-tetrahydro-2-oxothieno(3,4-d)imidazoline-4-valeric acid; the (+) enantiomer is very widely distributed in cells and serves as a carrier in a number of enzymatic beta-carboxylation reactions.
