Flashcards in Chapter 4 - Carbs Structure And Fx Deck (12):
**fischer, line, dash/wedge
To the drawing board!
What is absolute configuration ? What is relative?.
Absolute: R vs S
Relative : cis / trans
What do + and - denote for molecules?
The direction of rotation
*cannot be determined by L and D...needs to be experimentally
Type of diastereomers that differ in configuration by exactly one chiral centre
How many carbons are in Pyranose and furanose?
On a cyclic sugar, the carbon which is attacked by the OH ...Which becomes chiral
Forms alpha and beta anomers
**think of them relative to the CH2OH
Trans = alpha
Cis = beta
What is mutarotation?
Spontaneous change about C-1 carbon between alpha and beta
Draw the chair conformation of glucose
Another draw. Daniel, I’m going to have to trust you can do this
What is maltose made of of?
Glucose - glucose
Glucose and fructose
