A dipeptide is formed when two amino acids (in this case leucine and alanine) combine together. The -CONH- bond between the amino acid residues is called a peptide bond. If the condensation process is repeated with one more amino-acid it will make a tripeptide, or if many amino-acids are combined the result is a polypeptide. In each of these cases, there is an unattached amino group (-NH2) at one end as well as an unattached acid group (‑COOH) at the other end of the chain of amino acid residues. These are called the N-terminus and the C-terminus. Other options: Label the peptide bond atoms.

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. |
