Module 8: Carbohydrates Flashcards
(20 cards)
What is a Monosaccharide?
Are individual units that can be linked together.
If you form one glycosidic bond between two monosaccharide you have a?
Disaccharide
Linking 10 or so monosaccharide gives you an?
Oligosaccharide
Linking many hundreds of Monosaccharide into one large chain yields a? example glucose, cellulose or chitin
Polysaccharide
Aldose are found where?
are found at the end of the chain
Ketose are found where?
are found in the middle
3 Carbons are what?
Triose
4 Carbons are what?
Tetrose
5 Carbons are what?
Pentose
6 Carbons are what?
Hexose
7 Carbons are what?
Septose
Define Glucose?
The carbohydrate used to synthesize ATP during cellular respiration.
Define Galactose?
A structural component of cell membranes.
What is the difference between alpha and beta forms of glucose?
The OH & H switch sides
Produce a dehydration synthesis reaction
Remove H2O and bind the rest together
What are some functions of polysaccharides?
Store energy, as structural element of cells and organisms, or as signaling and cell recognition molecules.
What organisms is chitin found in?
They are found in insects shell (exoskeleton)
Alpha-glucose does what?
Starch glycogen
- (can process) digest energy storage. like potatoes
Beta-glucose
Cellulose
- we can’t digest it
- Structural support (tree)
What bonds hold monosaccharides together to form more complex structures
glycosidic linkages
