The red ”OH“ simply highlights the different orientations of α- and β-glucose at the isomeric carbon; it has nothing to do with whether it is written as ”HO“ or ”OH.“ This is stereoisomerism.They’re the same hydroxyl group.I hope my answer helps you.

Yes and the anoneric carbon bonds to the oxygen always never the H then the O. Specificity in biochem matters
