WASHINGTON — Use it as a postage stamp, not a chemistry text.
In spite of a small error in a chemical formula, the Postal Service is going ahead with a commemorative stamp honoring biochemist Gerty Cori.
She discovered cori ester, a derivative of glucose.
The formula is on the stamp. The error is in the placement of a line in the formula and does not create a new chemical, Postal Service spokesman Roy Betts said Tuesday.
The Cori stamp is among a set of four stamps honoring American scientists and is scheduled to be issued March 6.
The error was discovered by Chemical & Engineering News.
