Carbohydrate Structure Flashcards
Carbohydrate molecules are composed of what molecular building blocks?
- Carbon
- Hydrogen
- Oxygen
How many carbons are there usually in monosaccharides?
3-7 Carbons
What is the major storage carbohydrate in animals?
Glycogen
Glucose + Fructose = ____________
Sucrose
Glucose + Glucose = _____________
Maltose
The most stable conformation of glucose is the _______ conformation.
In this conformation the different constituents of glucose ( especially the bulky groups; -OH, CH2OH) are not crowded; hence more stable.
Chair
True or False. Sucrose is a non-reducing sugar.
True, Sucrose and Trehalose ( Sugars of Insect Hemolymph)
Isomers that differ in configuration around only one specific carbon atom are called?
Epimers
These are optical isomers or sterioisomers.
Enantiomers
Unlike epimers, Anomers can undergo interconversion from alpha to beta and vice versa) without energy expenditure or the need for enzymes, in a process called _______?
Mutarotation
What is the building block of all carbohydrates?
Monosaccharides
Refers to the network of polysaccharides projecting from cellular surfaces of bacteria.
Glycocalyx
Tissue with the highest total glycogen content.
Skeletal muscles
Has the highest glycogen content by tissue weight.
Liver
Are maltose, sucrose and lactose technically polysaccharides?
No
