|
The folding and shape have nothing to do with how a protein functions.

Detailed explanation-1: -Proteins fold up into specific shapes according to the sequence of amino acids in the polymer, and the protein function is directly related to the resulting 3D structure. Proteins may also interact with each other or other macromolecules in the body to create complex assemblies.
Detailed explanation-2: -Proteins are built as chains of amino acids, which then fold into unique three-dimensional shapes. Bonding within protein molecules helps stabilize their structure, and the final folded forms of proteins are well-adapted for their functions.
Detailed explanation-3: -Each protein normally folds up into a single stable conformation. However, the conformation often changes slightly when the protein interacts with other molecules in the cell. This change in shape is often crucial to the function of the protein, as we see later.
Detailed explanation-4: -Every protein has a shape that helps the molecule do its job. Collagen in our cartilage and tendons, for instance, has a three-stranded, rope-like structure that makes it strong. Enzymes-proteins that facilitate chemical reactions-typically have a pocket that holds the molecule they act upon.
