lipid transport nitrogen compound transport sphingoid long-chain base transport 2016-07-22T01:40:59Z GO:1905329 tb sphingoid transport sphingoid base(1+) transport phytosphingosine transport dihydrosphingosine transport biological_process long-chain base transport The directed movement of a sphingoid long-chain base, sometimes referred to as long-chain base, or sphingoid base, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Sphingoid long-chain bases are long-chain aliphatic amines that are the fundamental building blocks of sphingolipids. The main mammalian sphingoid long-chain bases are dihydrosphingosine and sphingosine, while dihydrosphingosine and phytosphingosine are the main sphingoid long-chain bases in yeast. sphingosine transport
