ComparisonofBetaoxidationinmitochondriaandperoxisomesandglyoxysomes
In addition to the beta-oxidation of fatty acids in mitochondria, animal cells carry out beta-oxidation in another organelle, the peroxisome. Although the mitochondrial and peroxisomal beta-oxidation pathways are similar, the details differ somewhat. Plants conduct beta-oxidation entirely in peroxisomes and glyoxysomes. Both pathways result in the progressive oxidation and release of two carbon acetyl groups from fat......阅读全文
