Cellulose and hemicellulose are examples of polysaccharides. Which of the options below best describes the molecular structure for each, as well as the key difference?
a. Cellulose and hemicellulose are both glucose polymers with β-1,4-glycoside bonds, but only hemicellulose has sidechains via β-1,2-glycoside bonds
b. Cellulose and hemicellulose are both glucose polymers with β-1,4-glycoside bonds, but only cellulose has sidechains via β-1,2-glycoside bonds
c. Cellulose and hemicellulose are both glucose polymers with β-1,2-glycoside bonds, but only hemicellulose has sidechains via β-1,4-glycoside bonds
d. Cellulose and hemicellulose are both glucose polymers with β-1,4-glycoside bonds, but only cellulose has sidechains via β-1,2-glycoside bonds
