What is a "glycosidic" bond?
a bond derived from two thiol groups
a bond that joins anomeric carbons to other compounds
Which polysaccharide consists of linear β 1 -> 4 linked glucose?
Cellulose
Chitin
α - Amylose

Is this sugar reducing or non-reducing? How do you know?
Reducing; there is a free -OH group on the anomeric carbon
Non-reducing; there is a free -OH group on the anomeric carbon
Reducing; there is a glycosidic bond with the anomeric carbon
Non-reducing; there is a glycosidic bond with the anomeric carbon

OH group at carbon 1
OH group at carbon 4
lack of O at carbon 3
OH group at carbon 2
