17. Monomer: 3 fatty acids + glycerol

18. Polar head Non-Polar head Phospholipids & steroids join together w/proteins in the cell membrane (&hormones)

19. Function Made mainly of carbon and hydrogen (few oxygen) Fat best method of STORING forms cell membranes Insulates nerve cells (myelin) Insulates body (maintains homeostasis)

20. How are complex carbohydrates formed and broken down?

21. Dehydration Synthesis Combining single compounds into a complex one by removing water monosaccharide + monosaccharide ----> disaccharide + water C 6 H 12 O 6 + C 6 H 12 O 6 ----> C 12 H 22 O 11 + H 2 O (Process forms disaccharides & polysaccharides)

22. Hydrolysis Addition of WATER to a compound SPLITS it disaccharide + H 2 O ---> monosaccharide + monosaccharide C 12 H 22 O11 + H 2 O ---> C 6 H 12 O 6 + C 6 H 12 O 6

23. Ms. Jackson’s Lunch

24. Bellchallenge: Describe what you see (at least 3 sentences) This is an amino acid. It is the monomer for a protein. It contains C, H, O and N. It has 3 groups: an amino group, an R-group, and a carboxyl group. The R-group is considered a variant group because it changes.

25. Friday 9/17/10 Agenda 1. Proteins 2. Test for Organic Substances (Parts C,D &E) 3. Complete analysis questions 4. HW: Venn Diagram- carbohydrates, lipids, proteins

26. Proteins aka…. Meat Polypeptide Whey Protein Peanut butter

27. Breaks down into microscopic molecules Meat Polypeptide Amino Acid Monomer: amino acid Polymer: polypeptide

28. Monomer: Amino Acids Contains C, H, O, N 20 types Has both hydrophobic & hydrophylic ends Differ in R-group R-group can be acidic, basic or neutral Makes polypeptide then makes proteins

29. Polymer: Polypeptide (peptide means bond) Formed by dehydration synthesis Sequence determined by DNA 3-D and folds to take up less space

30. Function of Proteins Provides us with building blocks for life! Also regulate most functions in a cell. Glycoproteins (antigens) Combines w/DNA to form chromosomes Turns genes on and off Antibodies (fights disease)

31. Function of Proteins Provides structure & strength (fibers) Transports molecules in & out cells Hemoglobin (transports O 2 ) Enzymes (speeds up rxns)- has – ase suffix Acts as hormones (insulin)- many proteins have suffix of -in

32. Bellringer : Describe in detail what you see in the diagram. (minimum 3 sentences) This is a picture of ATP. ATP is one type of polymer of a nucleic acid. It is made of adenine, sugar, and 3 phosphate groups.

33. Monday 9/20/10 Agenda 1. Nucleic Acids 2. FinishTest for Organic Substances (Parts C,D &E) 3. Complete analysis questions 4. HW due Friday: Venn Diagram- carbohydrates, lipids, proteins & nucleic acids

34. Nucleic Acids Contains C, H, O, N, P Monomer: NUCLEOTIDES Nucleotides consist of 3 parts: 1. 5-Carbon Sugar 2. Phosphate Group 3. Nitrogenous Base

35. Nucleotide: Nitrogen Bases 5 types Cytosine Guanine Adenine Thymine (in DNA only) Uracil (in RNA only) Purines or pyrimidines In DNA:In RNA:C-G A-TA-U

36. Nucleotides: 5-carbon sugar and phosphate group 2 types of sugars Rib ose (in RNA only) Deoxyrib ose (in DNA only) Phosphate group Contains phosphorus & oxygen Polymer: polynucleotide deoxyriboseribose

37. Function Polypeptide: DNA (deoxyribonucleic acid) contains the genetic code stores & transmit heredity/genetic information found in the nucleus (mitochondria) Double stranded (double helix)

38. Function Polypeptide: RNA (ribonucleic acid) Carries info from DNA to cell Helps in protein synthesis found in ribosomes & nucleoli Single stranded

39. Polypeptide: ATP Contains adenine, ribose sugar, 3 phosphates Stores and releases energy

42. Which biomolecule has the most energy!?

43. C-H bonds Count the number of C-H bonds in your monosaccharide picture. Count the number of C-H bonds in your saturated or unsaturated bond picture Which biomolecule (carbs or fats) have more C-H bonds?

44. The number of C-H bonds = the amount of energy The more C-H bonds a biomolecule has, the more energy it has! Fats have the most energy because they have the most C-H bonds!
