High latent heat of evaporation
Lower density when solid
What are the functions of water?
Important in reactions
Used to transport substances
Helps with premature control
Water is a habitat
What elements are carbohydrates made of?
Hydrogen, carbon and oxygen
What is the general formula of carbohydrates?
What is a polymer?
Long chain molecules
Linked up by monomers in a repeating pattern
What are the two types of glucose?
Alpha and Beta
Draw an alpha glucose molecule
Draw an beta glucose molecule
Describe the structure of glucose
A monoscaccride with 6 carbon rings
Describe the structure of ribose
A monoscaccride with 5 carbon rings
Draw a verbose molecule
What bond are monosaccharides joined by?
This is a condensation reactions (releases water)
What is a monosaccharide?
It is a simple sugar (CH4O)n
What is a disaccharide?
Double sugar two monosaccharide
What is a polysaccharide?
large molecules from many monosaccarides joined through condensation and glycosidic bonds
Describe the structure of the statch amylose
very compact therefore its good for stoage
Describe the structure of the statch amylopectin
Its in rows allowing it to be broken down easily and quickly
What is a hydrolysis reaction?
It is the breakdown of di/polysaccharides with addition of water molcules
What is the structure of glycogen?
Main energy storage in animals
What is the structure of cellulose?
Component in plant cell walls
Provides structural support
Compare glycogen and cellulose
- Alpha glucose
- Storage molecule
- Beta glucose
- Structural molcule
What makes up a triglyceride?
One glycerol molecule
Three fatty acid molcules
What type of bond is formed between the glycerol and fatty acids
Draw the chemical structure of a tryglceride
Which part of a fatty acid is hydrophobic and hydrophilic?
What is the difference between saturated and unsaturated
Unsaturated has at least one carbon double bond
What makes up a phospholipid
One glycerol molecule
Two fatty acid molecules
One Phosphate group
What are the main functions of triglycerides?
Energy storage in plants and animals
What are the main functions of phospholipids?
Make up a bilayer
Used in cell membranes
