In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by ...

Low-density lipoproteins (LDL) -- commonly known as bad cholesterol -- have long been on scientists' radar as a major contributor to heart disease. But these microscopic troublemakers have hidden ...

Why is knowing the atomic structure of molecules useful? Learn why, and how information like this about protein structure is shared through a publicly available database. Scientists use a variety ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...
