Molecule of the Month - July
Hi, July's MOTM is a familiar one, formaldehyde, and has been written by Walt Volland at the Bellevue Community College in Washington State. Only an HTMl version is available so far, but animated versions are on their way...

Hi, Does anyone have cyclodextrin (alpha, beta or gamma) in pdb or similar format? If so, I will greatly appreciate it if you send me the file or the URL where I can find it. So far, I have looked in several databanks and the only one file I have found is a cyclic heptamer of BETA!!! (1-4) glucose.
