Transcript

  1. Biochemistry Introduction of Macromolecules
  2. WORD BREAKDOWN: macromolecule
  3. WORD BREAKDOWN: macromolecule <ul><li>Macro </li></ul>Molecule Opposite of “micro” LARGE Molecule
  4. Biochemistry <ul><li>Biochemistry is the study of chemical reactions in living systems. </li></ul><ul><li>Biomolecules are organic compounds, meaning they are based on carbon chemistry. </li></ul><ul><li>Remember that carbon is unique in that it can form 4 covalent bonds; thus it is able to form long, complex chains of atoms. </li></ul>
  5. Organic Substances <ul><li>Organic substances , macromolecules , or biomolecules make up all living things. </li></ul><ul><li>The four groups of substances we will learn are: </li></ul><ul><ul><li>carbohydrates </li></ul></ul><ul><ul><li>lipids </li></ul></ul><ul><ul><li>proteins </li></ul></ul><ul><ul><li>nucleic acids </li></ul></ul>
  6. Organic Substances Poly mers are formed from the linking together of many similar mono mers .
  7. Organic Substances <ul><li>OK cool, but what do “ mono ” and “ poly ” mean? </li></ul>Hint: mono lingual, mono tone, & mono logue Mono = ONE!
  8. Organic Substances <ul><li>What does “ poly ” mean? </li></ul><ul><li>Hint: poly morphic and poly theism </li></ul>Poly = more than 1 OR many
  9. Organic Substances Poly mers are formed from the linking together of many similar mono mers . This statement should now make more sense now that we know the vocab root meaning!
  10. Organic Substances Think of biomolecules as “giant molecules” formed from thousands or hundreds of thousands of smaller molecules. Mono mers (links) are the smaller units which are joined together to form poly mers (bike chain)
  11. Organic Substances Structure Subunit Types Roles Examples Identification Carbohydrate Lipids Protein Nucleic Acid
  12. <ul><li>Carbon ring </li></ul><ul><li>C 6 H 12 O 6 </li></ul>Carbohydrates Organic compounds that have the formula C n (H 2 O) n or 1:2:1 http://www.wisc-online.com/objects/index_tj.asp?objid=AP13104
  13. <ul><li>Carbon ring </li></ul><ul><li>C 6 H 12 O 6 </li></ul><ul><li>Fuel for </li></ul><ul><li>Respiration </li></ul>Monosaccharides
  14. <ul><li>Carbon ring </li></ul><ul><li>C 6 H 12 O 6 </li></ul>Polysaccharides Starch A storage molecule found in plants. Plants store sugars in the form of starch for later use. Starch Starch Starch
  15. More to come about these two!
  16. Organic Substances Monosaccharides ??? (coming soon) Quick Energy ??? (coming soon) Glucose Fructose ??? (coming soon) Benedict’s Reagent ??? (coming soon) Structure Subunit Types Roles Examples Identification Carbohydrate Monosaccharides Lipids Protein Nucleic Acid
  17. Glycerol + Fatty Acid tails Lipids <ul><li>Comprised of C, H, and O. </li></ul><ul><li>Lipids are insoluble in water. </li></ul><ul><li>Lipids include phospholipids, and fats (AKA triglycerides). </li></ul>http://www.wisc-online.com/objects/index_tj.asp?objid=AP13204
  18. Glycerol + Fatty Acid tails Lipids Glycerol Fatty Acid tails
  19. What do these all have in common? Which one is different? A B C D E F
  20. <ul><li>Saturated </li></ul><ul><li>Animal fats </li></ul><ul><li>Solid at room temp </li></ul><ul><li>Lacks double bond in Carbon chain </li></ul><ul><li>Unsaturated </li></ul><ul><li>Plant fats </li></ul><ul><li>Remain liquid at room temp. </li></ul><ul><li>Has a double bond in Carbon chain </li></ul>Lipids
  21.  
  22. LIPIDS “ PHOSPHO”LIPID Cell Membrane
  23. LIPIDS What are trans fats ? UNSATURATED TRANS FAT
  24. LIPIDS <ul><li>Major Food Sources of Trans Fat for American Adults </li></ul>
  25. Organic Substances <ul><li>Cholesterol </li></ul><ul><li>Phospholipids </li></ul><ul><li>Fats: </li></ul><ul><li>Saturated </li></ul><ul><li>Unsaturated </li></ul>Stored energy Insulation Cell Components Fats Oils Waxes Sudan III Brown paper Glycerol + Fatty acids Structure Subunit Types Roles Examples Identification Carbohydrate Lipids Protein Nucleic Acid
  26. <ul><li>A central carbon atom </li></ul><ul><li>Is bonded to: </li></ul><ul><li>Amino group </li></ul><ul><li>Hydrogen atom </li></ul><ul><li>Carboxyl group </li></ul><ul><li>R group (varies) </li></ul>Proteins Proteins are macromolecules comprised of chains of amino acids. http://www.wisc-online.com/objects/index_tj.asp?objid=AP13304
  27. Organic Substances Many types Biuret’s Reagent Structure Subunit Types Roles Examples Identification Carbohydrate Lipids Protein Amino acids Nucleic Acid Meats Hormones Muscle Hair Nails Enzymes Blood Cells catalysts transport movement protection immune growth
  28. NUCLEIC ACIDS DNA RNA
  29. NUCLEIC ACIDS Nucleic acids are the only macromolecules with the unique ability to REPRODUCE themselves and carry the code that directs all of the cell’s activities.
  30. <ul><li>The subunits (monomers, building blocks) of nucleic acids are called </li></ul>NUCLEIC ACIDS NUCLEOTIDES. nitrogen base phosphate sugar (Pentose- 5 Carbon)
  31. NUCLEIC ACIDS The pentose (5 carbon) sugar in a nucleotide is either ribose (RNA) or deoxyribose (DNA).
  32. NUCLEIC ACIDS PHOSPHATE GROUP
  33. NUCLEIC ACIDS The NITROGEN BASES fit into 2 families: <ul><li>5 membered ring attached to a pyrimadine ring. </li></ul><ul><li>ADENINE (A) & GUANINE (G) </li></ul><ul><li>6 membered rings of carbon and nitrogen atoms. </li></ul><ul><li>CYTOSINE (C) </li></ul><ul><li>THYMINE (T) – DNA </li></ul><ul><li>URACIL (U) - RNA </li></ul>
  34. NUCLEIC ACIDS ATP ADENOSINE TRIPHOSPHATE An individual nucleotide that functions in energy transfer (acts like a battery) in the cell. adenine ribose triphosphate
  35. Organic Substances Direct cell processes Protein Synthesis Cellular energy DNA RNA ATP None  DNA RNA ATP Nucleotides Structure Subunit Types Roles Examples Identification Carbohydrate Lipids Protein Nucleic Acid
