How to now if the OH group on the C5 carbon of a cyclic sugar is up or down in Fischer Projection I know when using fischer projection I have to look if it's a D or L configuration. if it's D: up = right and down = left and if it's L: up = left and down = right. I think the concept is clear to me, however I dont't know if the OH group on the C5 carbon atom is pointing up or down. For example: 


When I have to draw those cyclic molecules to fischer projection I never know if the OH group which will be shown in the fischer projection (not in the clyic structure because it's a hemi-acetal then) is pointing up or down. What is the rule for this?

I want to get this: 

But I don't know how to know the side of the circled OH group
The OH group you've circled is always on the right hand side for D-sugars and on the left for L-sugars as its position is in the very definition of D/L sugars.
