  2. Kilocalorie per mole - Wikipedia

    en.wikipedia.org/wiki/Kilocalorie_per_mole

    It is defined as one kilocalorie of energy (1000 thermochemical gram calories) per one mole of substance. The unit symbol is written kcal/mol or kcalmol1. As typically measured, one kcal/mol represents a temperature increase of one degree Celsius in one liter of water (with a mass of 1 kg) resulting from the reaction of one mole of reagents.

  3. Glucose - Wikipedia

    en.wikipedia.org/wiki/Glucose

    Whereas molecular weight (molar mass) for D-glucose monohydrate is 198.17 g/mol, [49] [50] that for anhydrous D-glucose is 180.16 g/mol [51] [52] [53] The density of these two forms of glucose is also different. [specify] In terms of chemical structure, glucose is a monosaccharide, that is, a simple sugar.

  4. Calorie - Wikipedia

    en.wikipedia.org/wiki/Calorie

    [1] [2] The large calorie, food calorie, dietary calorie, kilocalorie, or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin). [1] [3] The small calorie or gram calorie is defined as the amount of heat needed to cause the same increase in one milliliter of ...

  5. Standard enthalpy of formation - Wikipedia

    en.wikipedia.org/wiki/Standard_enthalpy_of_formation

    The standard enthalpy of formation is measured in units of energy per amount of substance, usually stated in kilojoule per mole (kJ mol1), but also in kilocalorie per mole, joule per mole or kilocalorie per gram (any combination of these units conforming to the energy per mass or amount guideline).

  6. Table of specific heat capacities - Wikipedia

    en.wikipedia.org/wiki/Table_of_specific_heat...

    For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...

  7. Food energy - Wikipedia

    en.wikipedia.org/wiki/Food_energy

    It can take up to 20 hours of little physical output (e.g., walking) to "burn off" 17,000 kJ (4,000 kcal) [17] more than a body would otherwise consume. For reference, each kilogram of body fat is roughly equivalent to 32,300 kilojoules of food energy (i.e., 3,500 kilocalories per pound or 7,700 kilocalories per kilogram). [18]

  8. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    The Gibbs free energy for converting a mole of CO 2 to glucose is 114 kcal, whereas eight moles of photons of wavelength 600 nm contains 381 kcal, giving a nominal efficiency of 30%. [2] However, photosynthesis can occur with light up to wavelength 720 nm so long as there is also light at wavelengths below 680 nm to keep Photosystem II ...

  9. Blood sugar level - Wikipedia

    en.wikipedia.org/wiki/Blood_sugar_level

    Glucose homeostasis, when operating normally, restores the blood sugar level to a narrow range of about 4.4 to 6.1 mmol/L (79 to 110 mg/dL) (as measured by a fasting blood glucose test). [ 10 ] The global mean fasting plasma blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); [ 11 ] [ 12 ] however, this level fluctuates throughout ...
