Carbohydrates
Carbohydrates are made of carbon, hydrogen and oxygen. There are always twice as many hydrogens as oxygen.
There are three classes:Monosaccharides Slide9

There are three classes:MonosaccharidesDisaccharidesPolysaccharide Slide10
Carbohydrates
Monosaccharides serve as energy molecules for the cell.
There are many forms but the most common have the formula of C
6H12O6. Common examples are:Glucose

CarbohydratesSlide14
Carbohydrates
They only differ in how the elements are arranged. These are called structural isomers.
Monosaccharides are used as building blocks to make more complex carbohydrates.

Slide16
Carbohydrates
Disaccharides are formed from two monosaccharides.
Slide17
Carbohydrates
Disaccharides are formed from two monosaccharides.
The type of monosaccharides determines the type of disaccharide.
Slide18
Carbohydrates
Disaccharides are formed from two monosaccharides.
The type of monosaccharides determines the type of disaccharide.
All disaccharides are formed by the DEHYDRATION SYNHTESIS REACTION.Slide19
Carbohydrates
Three common disaccharides are:
Sucrose formed from glucose + fructose Slide20
Carbohydrates
Three common disaccharides are:
Sucrose formed from glucose + fructose
Lactose formed from glucose + galactose Slide21

Three common disaccharides are:
Sucrose formed from glucose + fructose
Lactose formed from glucose + galactose
Maltose formed from glucose + glucose Slide22
Carbohydrates
Three common disaccharides are:

CarbohydratesSlide27
Carbohydrates
Sucrose also known as table sugar is found in sugar cane.Slide28
Carbohydrates
Lactose also known as milk sugar. Are you lactose intolerant?Slide29
Carbohydrates
Maltose also known as malt sugar and is found in corn.Slide30
Carbohydrates
Polysaccharides are composed primarily of glucose.
Slide31
Carbohydrates
Polysaccharides are composed primarily of glucose.
There are four common types and they differ only in how the glucose molecules join together.
Slide32
Carbohydrates
Starch also known as amylose is found in plants. It stores excess glucose.Slide33
Carbohydrates
Glycogen is found in the liver and muscles of animals. It stores excess glucose.Slide34
Carbohydrates
Cellulose makes up the cell wall of plants. It serves a structural function.Slide35
Carbohydrates
Chitin makes up the exoskeleton of arthropods. Slide36
