L-leucine degradation GO:0006552 KEGG:map00290 KEGG:map00280 KEGG:map01110 KEGG:map01100 UPa:UPA00363 Degradation of L-leucine, one of the three main branched chain amino-acids (BCAAs), along with L-valine and L-isoleucine. In plants, branched-chain amino-acids are synthesized in chloroplasts, whereas the degradation takes place in mitochondria.
