[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is a pyridinecarbaldehyde that is pyridine-4-carbaldehyde bearing methyl, hydroxy and hydroxymethyl substituents at positions 2, 3 and 5 respectively. The 4-carboxyaldehyde form of vitamin B6, it is converted into pyridoxal phosphate, a coenzyme for the synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid. It has a role as a cofactor, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a vitamin B6, a pyridinecarbaldehyde, a member of methylpyridines, a monohydroxypyridine and a hydroxymethylpyridine. It is a conjugate base of a pyridoxal(1+)."}, {"from": "gpt", "value": "[C][C][=N][C][=C][Branch1][#Branch2][C][=Branch1][Branch1][=C][Ring1][=Branch1][O][C][=O][C][O]"}]
