  1. Biomolecules Tutorial Mrs. Scott

  2. To use this tutorial, you may either go through it as a PowerPoint, looking at the pictures and trying to identify them by their major classification of biomolecule and their division within that class, or printing this out (as handouts, 6 per page, horizontal), folding it in half, and using it as flashcards to do the same.

  3. Protein • Peptide chain- primary structure • There are nitrogens and hydrogens in the chain with a COO and NH3 end

  4. Carbohydrate Polysaccharide The rings have only carbon (not shown) and oxygen in them and are linked together.

  5. Carbohydrate Monosaccharide The ring has only carbon (not shown) and oxygen in it.

  6. Lipid • Fatty acid (saturated- all carbons filled up with hydrogens- no double bonds) • There is a long chain of carbons bonded to hydrogens with oxygen at one end.

  7. Carbohydrate • Monosaccharide • This linear form has only carbon, hydrogen, and oxygen in it in a 1:2:1 ratio.

  8. Protein • Amino acid, the monomer of a protein • There is a COO and NH3 end and a central Carbon with a H at one end and an R group (variable group) at the other end

  9. Lipid Phospholipid There is a phosphate end (with PO4), a glycerol (3 carbons, 3 oxygens and hydrogen) and two fatty acid chains (chains of C and H with oxygen at one end)

  10. Nucleic acid • Part of a nucleotide, a sugar and a nitrogen base • The sugar is a ring of carbons (not shown, but present at the bends), hydrogens and oxygens. The nitrogen base is a single or double ring with carbon and nitrogen in them.

  11. Lipid Phospholipid There is a head [with a phosphate end (with PO4), a glycerol (3 carbons, 3 oxygens and hydrogen)- not shown] and two fatty acid chains- squiggles (chains of C and H with oxygen at one end)

  12. Carbohydrate Monosaccharide The ring has only carbon (not shown) and oxygen in it.

  13. Carbohydrate Disaccharide There are two rings that have only carbon (not shown) and oxygen in them and are linked together.

  14. Nucleic acid • Part of a nucleotide, a nitrogen base • The nitrogen base is a single or double ring with carbon and nitrogen in them.

  15. Carbohydrate Polysaccharide The rings have only carbon (not shown) and oxygen in them and are linked together.

  16. Lipid • Steroid • There are interlocking carbon rings

  17. Protein • Amino acid, the monomer of a protein • There is a COO and NH3 end and a central Carbon with a H at one end and an R group (variable group) at the other end

  18. Carbohydrate Disaccharide There are two rings that have only carbon (not shown) and oxygen in them and are linked together.

  19. Protein • Tertiary structure, a chain of amino acids folded back on itself- globular. • Enzymes are proteins.

  20. Nucleic acid • Part of a nucleotide, a sugar and a nitrogen base • The nitrogen base is a single or double ring with carbon and nitrogen in them.

  21. Nucleic acid • ATP (adenosine triphosphate) a sugar, three phosphates and a nitrogen base • The sugar is a ring of carbons (not shown, but present at the bends), hydrogens and oxygens. The nitrogen base is a double ring with carbon and nitrogen in it. There are three PO4’s

  22. Carbohydrate • Monosaccharide • This linear form has only carbon, hydrogen, and oxygen in it in a 1:2:1 ratio.

  23. Lipid • Steroid • There are interlocking carbon rings with an attached fatty acid chain (zig-zag)

  24. Carbohydrate Polysaccharide The rings have only carbon (not shown) and oxygen in them and are linked together.

  25. Protein • Amino acid, the monomer of a protein • There is a COO and NH3 end and a central Carbon with a H at one end and an R group (variable group) at the other end

  26. Lipid • Steroid • There are interlocking carbon rings with an attached fatty acid chain
