Carbohydrates Flashcards
What is the general formula for monosaccharides?
Cn(H2O)n
What are the main three types of monosaccharides?
Trioses
Pentoses
Hexoses
What does deoxy mean?
One less oxygen
What is alpha glucose?
- Alpha configuration (OH on the bottom)
- Forms storage polysaccharides
What is Beta glucose?
- Beta configuration (OH on top)
- Forms structural polysaccharides
What is a disaccharide?
Formed when two monosaccharides join together in a condensation reaction
What is Maltose made of?
Glucose + Glucose
What is a polysaccharide?
Multiple glucose monosaccharides joined together in a condensation reaction
What is the bond between monosaccharides?
Glycosidic bonds
What are the main properties of storage polysaccharides?
- Compact (Helical and branched)
- Inert so it can’t diffuse out of the cell
- Insoluble in water so it doesn’t lower the cells water potential
- Branched so there are several ends for enzyme attachment.
- Quickly broken down into glucose
Where are starch molecules found and what are they made up of?
- 20% Amylose and 80% Amylopectin
- Found in chloroplasts or amyloplasts in plant cells depending on the need of the plant cell
- Stored at granules
What are the properties of amylose?
- Helical
- Unbranched chain of alpha glucose
- 1-4 glycosidic bonds
What are the properties of amylopectin?
- Branched
- Shorter chains of alpha glucose
- 1-4 and 1-6 glycosidic bonds
Where is glycogen found and what its properties?
- Found in cytoplasm of animal cells
- Highly branched as animals have a higher metabolic rate
- Compact and rapidly mobilised
- Insoluable
What are the main properties of structural polysaccharides?
Linear and unbranched
