L-Galactose + NAD → Hydrogen Ion + L-galactono-1,4-lactone + NADH
2 Ferricytochrome c + L-galactono-1,4-lactone → Ascorbic acid + 2 Ferrocytochrome c + 2 Hydrogen Ion
L-galactono-1,4-lactone (→) Transport: Arabidopsis thaliana, Cell, Mitochondrial Inner Membrane to Arabidopsis thaliana, Cell, Mitochondrial Matrix
Ascorbic acid + 2 Ferricytochrome c → Dehydroascorbic acid + 2 Ferrocytochrome c + 2 Hydrogen Ion
2 Ascorbic acid + Hydrogen peroxide → 2 Water + 2 monodehydroascorbate radical
Hydrogen Ion + NADH + 2 monodehydroascorbate radical → 2 Ascorbic acid + NAD
Amino Sugar and Nucleotide Sugar Metabolism
Guanosine diphosphate mannose ↔ GDP-L-gulose
Guanosine diphosphate mannose ↔ GDP-L-galactose
GDP-L-galactose + Phosphate → Guanosine diphosphate + L-galactose 1-phosphate
L-galactose 1-phosphate + Water → L-Galactose + Phosphate
