carbohydrates [carbo(n)hydr(ogen)ates] by weight. Plants can readily
manufacture carbohydrates in large quantities because carbon and
hydrogen are derived from air (C02) and water (H2O), both substances
being available to plants in almost unlimited quantities.

Sugar, manufactured by photosynthesis, is the simplest and most
vital carbohydrate. Sugar is "burned" in all plant cells as the
primary fuel powering all living activities. Extra sugar can be more
compactly stored after being converted into starches, which are long
strings of sugar molecules linked together. Plants often have
starch-filled stems, roots, or tubers; they also make enzymes
capable of quickly converting this starch back into sugar upon
demand. We homebrewers and bakers make practical use of a similar
enzyme process to change starches stored in grains back to sugar
that yeasts can change into alcohol.
