Maltose (4:11) C4-OH (left glucose) should be equatorial -- axial=galactose.  Thanks for the video!

4:28 The monosaccharide on the left is actually galactose. The OH on the #4 carbon is pointing up.

The first glucose of your Maltose Disaccharide has an OH in the axial position in C4 when it should be in the equatorial position. Am I right?

Is that really an acetal on the anomeric carbon of fructose? You mean a ketal?

maltose is made up of an alpha 1, 4 glycosidic bond between two alpha-D-glucose molecules (not glucose and galactose), but thank you overall this really helped even after 8 years lol.

If we cant break down Cellulose because of the Beta 1, 4 glycosidic bond, then why can we break down Lactose Beta 1 4 glycosidic bond?

Your definition of alpha and beta is wrong
