1. What are some other organic molecules? Lipids Fats

2. What are lipids used for in our bodies? Major component of cell membranes Important energy source

3. What are lipids made up of? A fat consists of a Glycerol molecule and 3 Fatty Acid chains

4. Fats can be Saturated or Unsaturated Can you see the difference? Unsaturated fats have double bonds in the fatty acid chains

5. Unsaturated vs. Saturated Fats Diets rich in saturated fats can lead to the build up of plaques in blood vessels.

6. What are steroids? Some hormones are steroids Very important component of the cell membrane

7. What organic molecule does this cat have too much of? LIPIDS

8. What is another category of organic molecules? Proteins

9. Proteins have many functions: Proteins are enzymes, found in cell membrane, make up antibodies, and much more

10. What are proteins made up of? Proteins are made up of polymers of amino acids

11. How do we build proteins? The functional groups of proteins interact with each other to form polymers of amino acids (proteins). Dehydration Synthesis

12. What are Polypeptides? Polypeptides are chains of amino acids Proteins are long chains of polypeptides

13. How many amino acids are there? There are only 20 amino acids, but there are millions of different types of proteins.

14. Protein Shape: 1)The sequence (order) of amino acids in a protein determine its shape 2) The shape of a protein determines its activity

15. 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!

16. What is another group of organic compounds? Nucleic Acids

17. DNA & RNA are Two Kinds of Nucleic Acids The building block of nucleic acids are: Nucleotides

18. What is a nucleotide made of?

19. What is DNA responsible for? Our characteristics or traits

20. Nucleic Acids DNA or RNA Nucleotides Phosphate Sugar Base

21. What are the 4 Organic Molecules: Carbohydrates Lipids Nucleic Acids Proteins
