D-Glucose, or dextrose, is a vital monosaccharide and primary energy source for cells, existing in Alpha and Beta forms. It is produced in plants through photosynthesis and is pivotal in metabolic pathways like glycolysis and the pentose phosphate pathway. D-Glucose's chemical properties, such as being a reducing sugar and its solubility, underpin its biological functions and industrial applications, including as a sweetener and in fermentation.

Explain mutarotation in D-Glucose.
Mutarotation is the interconversion between Alpha and Beta forms of D-Glucose, altering solubility and reactivity.
02
Contrast D-Glucose and L-Glucose.
D-Glucose and L-Glucose are enantiomers, meaning they are non-superimposable mirror images, affecting their biological interactions.
