Transcript What are some other organic molecules?

What are some other organic
molecules?
Lipids
Fats
What are lipids used for in our
bodies?
Major component
of cell membranes
Important energy
source
What are lipids made up of?
A fat consists of a Glycerol molecule and
3 Fatty Acid chains
Fats can be Saturated or
Unsaturated
Can you see the difference?
Unsaturated fats have double bonds in the
fatty acid chains
Unsaturated vs. Saturated Fats
Diets rich in saturated fats can lead to the build up
of plaques in blood vessels.
What are steroids?
Some hormones are
steroids
Very important component of
the cell membrane
What organic
molecule does
this cat have too
much of?
What is another category of organic
molecules?
Proteins
Proteins have many functions:
Proteins are enzymes,
found in cell membrane,
make up antibodies, and
much more
What are proteins made up of?
Proteins are made
up
of polymers of
amino acids
How do we build proteins?
The functional groups of proteins interact with each
other to form polymers of amino acids (proteins).
Dehydration
Synthesis
What are Polypeptides?
Polypeptides are chains of amino acids
Proteins are long chains of polypeptides
How many amino acids are there?
There are only 20
amino acids, but
there are millions
of different
types of proteins.
Protein Shape:
1)The sequence (order) of amino acids in a
protein determine its shape
2) The shape of a protein determines its activity
What does Denaturation mean?
An unfavorable change in
temperature, pH, or some
other quality of the
environment can cause a
protein to unravel and
lose its normal shape
Denatured proteins do not function properly!
INCORRECT FORM….. NO FUNCTION!
What is another group of organic
compounds?
Nucleic Acids
DNA & RNA are Two Kinds of
Nucleic Acids
The building block
of nucleic acids are:
Nucleotides
What is a nucleotide made of?
What is DNA responsible for?
Our characteristics or
traits
Nucleic Acids
Nucleotides
DNA or
RNA
Phosphate
Sugar
Base
What are the 4 Organic Molecules:
Carbohydrates
Lipids
Nucleic Acids
Proteins
