The glycine molecule in 3-D

The Glycine molecule - rotatable in 3 dimensions

3 letter code:     gly        1 letter code:    G
Glycine is the simplest amino acid. It can also be described as aminoethanoic acid or aminoacetic acid.

Like all amino acids, it has an amino group (-NH2) - blue with 2 white balls - at one end, and a carboxylic acid group (-COOH) - grey, connected to red, and red and white - at the other end.

Its 'R' group is simply a hydrogen, one of the white balls attached to the central carbon atom. This is often described as the α- (alpha) carbon.

You can move this molecule in 3 dimensions by holding down the left button and dragging using the mouse.

If you have a central mouse wheel you can usually zoom the image in/out.

Right clicking gives a variety of display options.

Simply leaving the mouse pointer over one of the atoms will give information about it; the atom symbol, and some other less useful numerical information.
