| Isoleucine is an aliphatic amino acid. It is an isomer of leucine.
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. Between these is the a- (alpha) carbon to which the 'R' group is attached. In isoleucine, the 'R' group is an iso butyl group (-C4H9): -CHCH3-CH2CH3.
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. |
