The directed movement of amino acids containing sulfur (cystine, methionine and their derivatives) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

A series of processes that forms an integrated mechanism by which a cell or an organism detects the depletion of primary sulfur sources and then activates genes to scavenge the last traces of the primary sulfur source and to transport and metabolize alternate sulfur sources. The utilization process begins when the cell or organism detects sulfur levels, includes the activation of genes whose products detect, transport or metabolize sulfur-containing compounds, and ends when the sulfur is incorporated into the cell or organism's metabolism.

The directed movement of dicarboxylic acids into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
