Step 1. Glucose (a 6-carbon aldohexose) reacts with HCN to add across its aldehyde carbon, forming a cyanohydrin: CH(OH)(CN)-(CHOH)₄-CH₂OH -- a 7-carbon chain, since the nitrile carbon becomes a new C1.

Step 2. Hydrolysis of the -CN (nitrile) group converts it to a -COOH (carboxylic acid) group, giving a 7-carbon polyhydroxy acid: HOOC-CH(OH)-(CHOH)₃-CH₂OH-type heptonic acid, still bearing several -OH groups along its chain. …
