Determination of Significance：
L-galactose way is the key for the synthesis of AsA. Gal LDH is located in the mitochondrial inner membrane and is responsible for the final step of catalyzing the biosynthesis of AsA in plants. Gal LDH is one of the key enzymes in this pathway. It plays an important role in the accumulation of AsA in plants.
Measurement Principle：
Gal LDH catalyzes the reduction of L-galactonolactone to oxidized cytochrome c (Cyt c). Reduced Cyt c has an absorption peak at 550 nm. Measure the increasing rate of reduced Cyt c can calculate the activity of Gal LDH.
Self Provided：
Spectrophotometer, desk centrifuge, adjustable pipette, 1 mL glass cuvette, mortar/homogenizer, ice and distilled water.
