-List of pathways: carbohydrate digestion (won't talk about), fructose metabolism, galactose metabolism, glucose oxidation (etc., basically cell resp), glycogenesis, glycogenolysis, pentose phosphate pathway, gluconeogenesis

-The most common carbohydrates consumed by humans are detailed in a table

Sucrose (table sugar, hexose)

Lactose (milk sugar, hexose)

Galactose (fermented products, hexose)

Maltose (hydrolysis of starch, hexose)

Xylose (fruits, pentose)

Arabinose (fruits, pentose)

-The metabolism of carbohydrates is the main way that human bodies generate energy

-This metabolism is closely regulated to maintain necessary levels of glucose throughout the body

Source 10[10]

-Glucose is an extremely important fuel for humans

-Standard free energy change for Glucose to CO2 and Water is -2840kJ

-Glucose can be stored as glycogen or starch, and released when needed

-Glucose also serves as a precursor to a variety of other intermediates (there are hundreds or thousands of transformations of glucose)

-Four major fates: synthesis of complex polysaccharides used in extracellular space; stored in cells; oxidized to pyruvate (glycolysis), to provide ATP and intermediates; or oxidized by pentose phosphate pathway to produce ribose 5-phosphate, which is used in creating nucleic acids and NADPH

-Some organisms fix glucose from atmospheric CO2 via photosynthesis (reducing CO2 to trioses, then converting to glucose)
