Proteins and Fats
All proteins, regardless of the source, animal, plant, fungal or bacterial, are all made from the same 20 amino acids.
Proteins and Fats
All proteins, regardless of the source, animal, plant, fungal or bacterial, are all made from the same 20 amino acids.
Amino acids contain carbon, hydrogen, oxygen and NITROGEN
Proteins and Fats
Amino Acid StructureAll amino acids have the following common structure.

Amino Acid Structure
The side group is what makes each amino acid unique.
Proteins and Fats
Proteins and Fats
Proteins are joined together by the DEHYDRATION SYNTHESIS REACTION.
Proteins and Fats
How can 20 amino acids make all the proteins found in living organisms?

How can 20 amino acids make all the proteins found in living organisms?
Different combinations and lengths(Letters of the alphabet)
Proteins and Fats
Each amino acid is like a letter in the alphabet, the change of one amino acid can change the shape of the protein.
Proteins and Fats
This is seen in hemoglobin where one acid change results in Sickle Cell Anemia.
Proteins and Fats
Proteins have a specific three dimensional shape which is important in their biological role.
Proteins and Fats
Proteins and Fats
The shape of a protein is influenced by temperature and pH.
Out side of a specific range the protein breaks down, its DENATURED.

Proteins and Fats
All lipids, regardless of the source, animal, plant, fungal or bacterial, are composed of carbon, hydrogen and oxygen.
They are nonpolar (do not dissolve in water)
Proteins and Fats
All lipids, regardless of the source, animal, plant, fungal or bacterial, are composed of carbon, hydrogen and oxygen.
They are made of two molecules: glycerol

Fatty Acid Structure
They can exist as two types, saturated and unsaturated.
Proteins and Fats
Fatty Acid Structure
They can exist as two types, saturated and unsaturated.
They can range from 12 to 22 carbons in length.
