The chemistry of amino acid side chains is critical to protein structure because these side chains can bond with one another to hold a length of protein in a certain shape or conformation.

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 ...

Learn why, and how information like this about protein structure ... portions of the macromolecular chain. Scientists then use this information to infer the structure of the biomolecule.

Consequently, they are fundamental components of our bodies and vital for physiological functions such as protein synthesis, tissue repair and nutrient absorption. Here we take a closer look at amino ...

Scientists have for the first time looked deep into the protein structure that may determine our vision—and discovered that ...

However the protein chains are arranged ... This explains the difference in structure between a raw egg and a fried egg.

This process, known as condensation or dehydration synthesis, results in the formation of a linear chain of amino acids. The sequence of amino acids in a protein, known as its primary structure, ...

The team engineered special “pockets” within a protein cage structure called ferritin ... orientation of the surrounding aromatic side chains. Through detailed X-ray crystallography analysis ...

Their function comes not only from the activity of the various amino acids, but also from the overall shape and structure of the folded protein chain. It is this that led Professor Andrew Wilson at ...
