Structure Flashcards
(10 cards)
What’s the formula for a hexose sugar?
(CH2O)6
How many carbons does glucose have?
6
What are the 2 structural variations of glucose?
Alpha
Beta
What makes glucose polar and soluble?
Due to the hydrogen bonds that form between the OH groups and water molecules
Why is glucose the main energy source in plants?
Soluble —> easily transported
It’s chemical bonds contain lots of energy
What’s the difference in structure between alpha and beta glucose?
The position of the hydroxyl group on the first carbon
What’s a way to remember this structure?
A - alpha
B - below
B - beta
A - above
How do you count the carbons on a structure?
Start with the carbon to the right of the oxygen atom and count clockwise
What is an isomer?
Molecules that have the same molecular formulae but a different arrangement of atoms
What is a glycosidic bond?
A covalent bond formed when 2 carbohydrate molecules and joined together by a condensation reaction
