WebMay 17, 2024 · The structure of a protein is very important to the function of the protein. There are many forces that drive the structure of a protein, including: electrostatic forces, hydrogen bonding, hydrophobic forces, and disulfide bonds. External forces like temperature and pH can also alter the structure of a protein; this is called denaturation. WebJan 3, 2024 · A structural domain is an element of the protein's overall structure that is stable and often folds independently of the rest of the protein chain. Like the PH domain above, many domains are not unique to the protein products of one gene, but instead appear in a variety of proteins. flower delivery bucks
