Answer:
a) L sugar
b) Aldose
c) Hexose
d) Beta anomer
Step-by-step explanation:
a) Here, we want to know if the given molecule is an L or D sugar
To know this, we consider the 2nd carbon from bottom
If the -OH group attached to it is on the left, then it is an L sugar. If it is on the right, then it is a D sugar
From what we have in the diagram shown, the -OH group is on the left, thus it is an L sugar
b) We look at the functional group at the very top
We can see the aldehyde bond (CHO)
Thus, we conclude that it is an aldose
c) What we have here is a hexose. This is because we can see six carbon atoms in the principal chain of the molecule
d) Alpha or Beta anomer
To get this, we look at the first and fifth carbon.
We look at the OH attached
If they are on the same side, it is an alpha anomer, else it is a beta anomer
In this case, they are not. Thus it is a beta anomer
