Concept introduction: The ascorbic acid is also known as L-ascorbic acid, which is a vitamin C element as well as an antioxidant. The enzyme GDP-D-mannose-3, 5-epimerase is an enzyme of isomerase family.
(c)
To explain: The enzyme phosphoglucose isomerase with reaction given for the ascorbic acid biosynthesis pathway.
Concept introduction: Ascorbic acid is also known as L-ascorbic acid, which is a vitamin C element as well as an antioxidant. Phosphoglucose isomerase is the isomerase enzyme.
(d)
To explain: The enzyme phosphomannose isomerase with reaction given for the ascorbic acid biosynthesis pathway.
Concept introduction: Ascorbic acid is also known as L-ascorbic acid, which is a vitamin C element as well as an antioxidant. The enzyme phosphomannose isomerase is the facilitating enzyme that interconverts two molecules.
(e)
To explain: The enzyme phosphomannose mutase with reaction given for the ascorbic acid biosynthesis pathway.
Concept introduction: The ascorbic acid is also known as L-ascorbic acid, which is a vitamin C element as well as an antioxidant. The enzyme phosphomannose mutase is a catalytic enzyme.
