Aldehydes and ketones react with alcohols by acid-initiated nucleophilic addition to form hemiacetals which are usually unstable. Reaction with a second mole of alcohol produces a acetal. Carbohydrates usually exist in hemiacetal or acetal forms.

Heterotrophs utilize organic compounds such as alcohol, acetate, carbohydrates, and fats as sources of energy. The same compound serves both as building material for cell synthesis and as an energy source, and therefore is not completely converted to end products such as CO2 and water. One may ask how efficiently energy is utilized for the formation of new material. Under proper conditions it is possible to measure changes in the amounts of various materials directly or indirectly by calorimetry or respirometry, and to determine the machine efficiencies of the reactions with the aid of free energy data. Machine efficiency is de-...
