碳水化合物的代謝作用
  • Fig 4-10
  • EMP pathway: Anaerobic fermentation
  • TCA cycle: Aerobic fermentation
anaerobic fermentation
Anaerobic Fermentation
  • Glycolysis
  • Entner-Doudoroff (ED) pathway
  • Heterolactic fermentation
  • Acetone-butanol and butyric acid fermentation
  • Mixed organic acid fermentation
  • Hexose-monophosphate shunt (HMP)
aerobic fermentation
Aerobic fermentation
  • Tricarboxylic acid cycle (TCA cycle)
  • Glyoxylic acid cycle
glycolysis
Glycolysis
  • 又稱Embden-Meyerhof-Pernas pathway, 簡稱EMP路徑 (Fig4-11)
  • 在厭氧條件下,由於微生物所引起之碳水化合物之代謝作用.
  • 包括:
    • 酵母的酒精發酵
    • 乳酸菌的乳酸發酵
    • 大腸菌的發酵
slide6
酒精發酵
  • Pyruvic acid CH3HO Ethanol
  • Pyruvic acid CH3HO Glycerin

Dehydrogenase

Decarboxylase

Na2SO3

slide7
正常乳酸發酵
  • Pyruvic acid Lactic acid

Lactic dehydrogenase

slide8
解糖作用

基質為肝糖

乳酸為L型

乳酸發酵

葡萄糖

依菌種而不定,有D型,L型及DL型

高等生物的解糖作用與乳酸發酵不同處
enter doudoroff pathway
Enter-Doudoroff pathway
  • 簡稱ED pathway
  • Fig4-13
heterolactic fermentation
Heterolactic Fermentation
  • 乳酸菌利用葡萄糖發酵的結果
  • 除生成乳酸之外,尚能伴生乙醇和CO2
  • Fig4-14
  • 一部份路徑與EMP路徑相同
hexose monophosphate shunt hmp
Hexose-monophosphate shunt (HMP)
  • Fig4-17
  • Fig 4-18
  • EMP pathway and HMP pathway, Fig4-19
  • Radioactive isotope tracer method
aerobic fermentation tricarboxylic acid cycle tca cycle
Aerobic Fermentation -Tricarboxylic acid cycle (TCA cycle)
  • Fig4-22
  • 1 Pyruvic acid 3 CO2 + 15 ATP
  • 1 Glucose 38 ATP (Table 4-4)
aerobic fermentation glyoxylic acid cycle
Aerobic Fermentation - Glyoxylic acid cycle
  • The relationship between Glyoxylic acid cycle and TCA cycle (Fig4-23)
slide15
脂質的代謝
  • 脂肪脂肪酸 + 甘油
  • Fig4-24:脂肪的beta氧化路徑
slide16
其他碳水化合物之代謝作用
  • 芳香族化合物之代謝作用
    • 以甲皖或甲醇為碳源之氧化途徑:

CH4CH3OH HCHO CO2

  • C1-化合物之代謝路徑
    • 有兩種:
      • Serine
      • Allulose
    • Fig 4-26
