Explain mutarotation using as an example mutarotation of D-galactose

Explain mutarotation using as an example mutarotation of D-galactose
I need help interpreting this galactose pathway in E.coli .Could
someone explain it please.

Amylopectin is composed of A) glucose and fructose B) galactose and fructose C) glucose D) galactose E) glucose and lactose
ON Lactose D-galactose D-glucose If additional galactose is added to the reaction mixture, what do you expect to happen to the glucose concentration? (Use Le Chatelier's Principle to answer this question). a) The glucose concentration won't change Ob) The glucose concentration will go down Oc) The glucose concentration will go up d) There is no glucose in the reaction mixture
Which structure represents a-D-galactose?
Write the cyclic forms of D-galactose.
Question 3 Hint: D-glucose, D-mannose and D-galactose are aldohexoses D-mannose is a C-2 epimer of D-glucose D-galactose is a C-4 epimer of D-glucose a) Draw the structures of D-mannose and a-D-mannose. b) Draw the structures of D-galactose and B-D-galactose
