Structure
To the right is the of Alpha Lactalbumin which is found in cow milk.
The of the protein is displayed. Alpha helix are shown as rockets and beta strands as planks. Random coils are white.
Hydrophobic and polar areas
structure where pink balls are polar. Grey is hydrophobic and green balls are calcium molecules.
Chain of amino acids
figure is displayed where the carboxyl terminal is in red and the Nitrogen terminal is in blue. The is noted with (*)while the atoms connected to it are displayed in ball and stick structure. The lysine is bind to the atoms by hydrogen and hydrophic bonds. Another example is the cystine residues binded to the protein by which are displays with the red small balls.
The Cationic and anionic residues
structre where red mean cationic and blue means anionic. Red sidechain are oxygens in Asp and Glu, sidechain nitrogens are in Lys, Arg, and His.
The distribution of polar and nonpolar side chain
are noted with a white (*) while the nonpolar side chains are not noted.
Ligands
Calcium is the ligand in the alpha lactalbumin. It is not part of the amino acid chain however; it is an important component of the protein. Calcium is bonded to the protein through . The calcium is displayed in green.
