N(omega),N(omega)-dimethyl-L-arginine catabolic process
n(omega),n(omega)-dimethyl-l-arginine catabolic process
The chemical reactions and pathways resulting in the breakdown of N(omega),N(omega)-dimethyl-L-arginine, a methyl-L-arginine having two methyl groups both attached to the primary amino moiety of the guanidino group.
