A polypeptide is an organic polymer that consists of a large number of amino acids linked together in a chain. The shape of a polypeptide determines its function.
Proteins with more than one polypeptide chain have a quaternary structure. This structure is formed by the assembly of multiple polypeptide chains into a functional protein complex. The interactions between the individual polypeptide chains contribute to the overall structure and function of the protein.
This is the mature protein shape that is the result of the many bonds made by the various R groups of the different amino acids. Hydrophobic and hydrophillic bonds, hydrogen bonding, sulfur covalent bonds and the like twist the protein into its globular shape.
When a globular protein has its hydrogen bonds broken, it can become denatured. This disrupts its folded structure, causing it to lose its specific shape and potentially its function. This could be reversible or irreversible depending on the extent of damage to the protein.
The one characteristic of solids that sets them apart from liquids, gasses and plasmas more than anything else is the ability to retain their own shape rather than assuming the shape of their containers.
Boiling point is a characteristic property of an element. It is the temperature at which a substance changes from a liquid to a gas at a given pressure. The boiling point of an element is unique and can be used to help identify the substance. Shape, volume, and weight are not characteristic properties of an element.
quaternary structure
Fibrous polypeptide chains are a type of protein structure known as secondary structure, while globular polypeptide chains are associated with tertiary structure. Globular proteins typically have a compact, rounded shape, while fibrous proteins have a more elongated, fibrous shape.
The protein would have a tertiary structure. This structure results from the unique folding of the single polypeptide chain into a 3D shape, giving the protein its functional conformation.

Tritiory proteins are globular proteins. Every enzyme is a globular proteins.

Myoglobin is typically described as a globular protein due to its compact, spherical shape. It is made up of a single polypeptide chain folded into a three-dimensional structure that allows it to bind and store oxygen in muscle tissues. This shape enables myoglobin to perform its function efficiently within muscle cells.
primary structure
The shape is not a characteristic of chemical elements but is a characteristic of objects.
Myoglobin has a globular shape, which is typical of many proteins. This structure consists of a single polypeptide chain that folds into a compact, spherical form, allowing it to effectively bind and store oxygen in muscle tissues. The presence of heme groups within its structure contributes to its functionality and stability. Overall, myoglobin's shape facilitates its role in oxygen transport and storage.
