Biologically Important Molecules

Carbon, Hydrogen, Oxygen and Nitrogen are the primary elements in these compounds.

Because they contain carbon they are classified as________ compounds.

Carbohydrates

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

Carbohydrates

Monosaccharides serve as energy molecules for the cell.There are many forms but the most common have the formula of C6H12O6.

Common examples are:Glucose

Carbohydrates

Page 14: Biologically Important Molecules. There are four biologically important groups of molecules found in living organisms. They are:  Carbohydrate.

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.

Carbohydrates

Disaccharides are formed from two monosaccharides.

Page 17: Biologically Important Molecules. There are four biologically important groups of molecules found in living organisms. They are:  Carbohydrate.

Carbohydrates

Disaccharides are formed from two monosaccharides. The type of monosaccharides determines the type of disaccharide.

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.

Carbohydrates

Three common disaccharides are: Sucrose formed from glucose + fructose

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

Page 21: Biologically Important Molecules. There are four biologically important groups of molecules found in living organisms. They are:  Carbohydrate.

Carbohydrates

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

Carbohydrates

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

All are formed using the dehydration synthesis reaction and have the formula C12H22O11.

Page 23: Biologically Important Molecules. There are four biologically important groups of molecules found in living organisms. They are:  Carbohydrate.

Carbohydrates

WAIT!!!!!!!!!!!!!!!!!!!!!!!!!!!Shouldn’t the formula be C12H24O12 ?

Dehydration means loss of water.

C6H12O6 + C6H12O6 C12H22O11 + H2O
