Webb4 maj 2024 · 2. Secondary Structure . Secondary Structure refers to the coiling or folding of a polypeptide chain that gives the protein its 3-D shape.There are two types of secondary structures observed in proteins. One type is the alpha (α) helix structure.This structure resembles a coiled spring and is secured by hydrogen bonding in the polypeptide chain. In biochemistry, a conformational change is a change in the shape of a macromolecule, often induced by environmental factors. A macromolecule is usually flexible and dynamic. Its shape can change in response to changes in its environment or other factors; each possible shape is called a conformation, and a transition between them is called a conformational change. Factors that may induce such changes includ…
