Note 8 — Chapter VII · STARCH AND SUGAR FORMATION.
Reading edition
In the formation of starch during photosynthesis the separated molecules from the carbon dioxide and water unite in such a way that carbon, hydrogen, and oxygen are united into a molecule of starch. This result is usually represented by the following equation: CO₂ + H₂O = CH₂O + O₂. Then by polymerization 6(CH₂O) = C₆H₁₂O₆ = grape sugar. Then C₆H₁₂O₆-H₂O = C₆H₁₀O₅ = starch. It is believed, however, that the process is much more complicated than this, that several different compounds are formed before starch finally appears, and that the formula for starch is much higher numerically than is represented by C₆H₁₀O₅.
