A complex project to produce a substance similar to the production of alkali from seawater?
On September 24th, 20021,Tianjin Institute of Industrial Biotechnology of China Academy of Sciences published a paper in the international academic journal Science, which realized the whole process of synthesizing corn starch for the first time. The following is from CO? The main steps of synthesizing starch are as follows:

Note: The following steps may require some key catalysts or conditions such as temperature and pressure, and some are not disclosed, so I have omitted them all.

⑴、CO? +3H? =CH? Oh +H? O(CH? Oh: methanol)

⑵、2CH? Oh +O? =2HCHO+2H? O (formaldehyde)

⑶、3HCHO=HOCH? COCH? Oh (HOCH? COCH? Oh: 1, 3- dihydroxyacetone)

⑷、HOCH? COCH? OH+ATP=H? Po. OCH? COCH? OH+ADP

ATP: abbreviation of adenosine triphosphate, which is the most important energy-supplying substance in organisms.

ADP: abbreviation for adenosine diphosphate, which is obtained by losing a phosphate unit from ATP.

h? Po. OCH? COCH? OH: dihydroxyacetone phosphate

⑸、H? Po. OCH? COCH? OH=H? Po. OCH? Jojo

h? Po. OCH? Chohcho: glyceraldehyde 3- phosphate, an isomer of dihydroxyacetone phosphate.

⑹、2H? Po. OCH? CHOHCHO = F- 1.6-BP

F- 1, 6-BP: fructose-1, 6- diphosphate with an oxygen-containing five-membered ring in the middle. The chemical formula is really difficult to write, so we have to use code names. The molecular structure is shown in the following figure:

⑺、F- 1,6-BP+H? O=F-6-P+H? Po.

F-6-P: fructose-6-phosphate is formed by hydrolysis of fructose-1, 6- diphosphate to remove a phosphoric acid, and its molecular structure is shown in the following figure.

⑻、F-6-P=G-6-P

G-6-P: glucose -6- phosphate, or glucose -6- phosphate, which has an oxygen-containing six-membered ring in its molecule and is isomerized from fructose-6-phosphate. The molecular structure is shown in the following figure:

⑼、G-6-P=G- 1-P

G- 1-P: glucose-1- phosphate, or 1- phosphate glucose, which is isomerized from glucose -6- phosphate. The molecular structure is shown in the following figure:

⑽、G- 1-P+ATP+2H? O=ADPG+2H? Po.

ADPG: adenosine diphosphate glucose, which is formed by the condensation of glucose-1- phosphate and adenosine triphosphate (ATP) after removing two units of phosphate. The molecular structure is shown in the following figure:

⑾、ADPG → [C? Huh? ]? +ADP

【C? Huh? ]? Polyglucose (corn starch), a polymerized long-chain molecule, has the following molecular structure:
