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

Biologically Important Molecules
There are four biologically important groups of molecules found in living organisms.
They are:CarbohydrateLipidsProteins &Nucleic Acids
Biologically Important Molecules
Carbon, Hydrogen, Oxygen and Nitrogen are the primary elements in these compounds.
Because they contain carbon they are classified as________ compounds.
Biologically Important Molecules
Carbon, Hydrogen, Oxygen and Nitrogen are the primary elements in these compounds.
Because they contain carbon they are classified as Organic 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
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.
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
Carbohydrates
Three common disaccharides are: Sucrose formed from glucose + fructose Lactose formed from glucose + galactose
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.
Carbohydrates
WAIT!!!!!!!!!!!!!!!!!!!!!!!!!!!Shouldn’t the formula be C12H24O12 ?

WAIT!!!!!!!!!!!!!!!!!!!!!!!!!!!Shouldn’t the formula be C12H24O12 ?
Dehydration means loss of water.
C6H12O6 + C6H12O6 C12H22O11 + H2O
Carbohydrates
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.
Carbohydrates
Carbohydrates
Sucrose also known as table sugar is found in sugar cane.
Carbohydrates
Lactose also known as milk sugar. Are you lactose intolerant?
Carbohydrates
Maltose also known as malt sugar and is found in corn.
Carbohydrates
Polysaccharides are composed primarily of glucose.
Carbohydrates
Polysaccharides are composed primarily of glucose.
There are four common types and they differ only in how the glucose molecules join together.
Carbohydrates
Starch also known as amylose is found in plants. It stores excess glucose.
Carbohydrates
Glycogen is found in the liver and muscles of animals. It stores excess glucose.
Carbohydrates
Cellulose makes up the cell wall of plants. It serves a structural function.
Carbohydrates
Chitin makes up the exoskeleton of arthropods.
