It is shown how a single graph-theoretical property of . often gives rise to several independent ring properties of ., thus making Leavitt path algebras as effective tools in constructing examples of rings with various desired properties. Leavitt path algebras satisfying

This result utilizes the Structure Theorem for Graded Ideals together with the analysis of the ideal generated by vertices which lie on cycles having no exits. A number of ring-theoretic results follow almost immediately from the Structure Theorem for Ideals
