Aldehyde, any of a class of organic compounds, in which a carbon atom shares a double bond with an oxygen atom, a single bond with a hydrogen atom, and a single bond with another atom or group of atoms (designated R in general chemical formulas and structure diagrams).
The records of the compound database include various compound specific information, in particular the chemical names, molecular formulas, and structure diagrams.
The National Institute of Standard and Technology NIST) and SureChem Chemical searches(for details, see URL link below) were finally employed to relate the former formulae to chemical formulae and structure of all known compounds in the respective databases.
These features included compound names, chemical formulae and structures, and enzymes catalysing reactions where the considered metabolites participate.
However, the number of possible chemical formulas and structures increases dramatically with mass, resulting in a very large number of "candidate formulas".
The chemical formula and crystal structure of the GaM4X8 lacunar spinels are easily deduced from the spinel with half-deficient Ga atoms, that is, Ga0.5M2X4.
Zeolites with varying Si/Al ratio, were synthesized using silica and alumina powder and by matching the XRD patterns with those given in the JCPDS files their chemical formula and crystal structure were determined.
While Tang doesn't necessarily agree, he did concede that the Vastrm formula and the structure the team built around it could easily be rejiggered to churn out other custom garments.

Zimmer [ 18] also identified features of the wing formula and nostril structure that separated E. ruficeps and E. cristata from the rest of the genus.
