Structure of Carbohydrates Flashcards
How much energy is released per gram of carbs consumed?
4.2 kcal/g
What are the requirements for complete oxidation of carbs, when compared to lipids?
Carbohydrates require less oxygen than lipids for complete oxidation but produce less energy per gram.
What is the carbonyl group, present in carbohydrates?
Bonds of one carbon, hydrogen and oxygen. This group gives carbs the [CHO] abbreviation.
What is the ‘carbon skeleton’ in carbohydrates?
Structure of carbon atoms that make up the main structure of carbohydrates. Oxygen and hydrogen then bind to the carbon.
What is an isomer?
A molecule with the same molecular formula and atomic mass, with the atoms arranged in a different order.
What formula do all carbohydrates follow?
Cn(H2O)n, with n = the number of carbon atoms in the molecule.
What are the three classifications of carbs?
Monosaccharides
Disaccharides
Polysaccharides
