A protein folded into a globular shape in having only one polypeptide chain has what structure?
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.
What shape is the protein actin?
Actin is a globular molecule
How do globular proteins relate to the structure level?
Globular proteins are a type of protein that typically have a compact, rounded shape. They are characterized by their three-dimensional structure, which consists of intricate folding patterns that enable them to carry out specific functions in the body, such as enzyme activity or transport. The overall structure of globular proteins helps determine their function and activity.
What is the Folding of proteins?
Protein folding determines the shape of the protein, and thus what it does, because it is the shape of the protein which enables it to perform its function. For example, enzymes need to have exactly the right shape to fit with the molecules they are working with to catalyze them. Also, hemoglobin is specifically folded with four pocket like areas to allow oxygen to attach to it. The shape of the protein is specific to the function that it is performing, and is different for each protein. If there is even a slight change in the make up of the protein, or a mutation (the amino acids are messed up) then the protein will fold differently. Even a slight change in the composition of the protein can disable the protein from properly performing the function which it is meant to do.
What type of secondary structure does hemoglobin have?
Hemoglobin is a protein with a combination of secondary structures, predominantly consisting of alpha helices and beta sheets. These structural elements help maintain the shape and function of hemoglobin as a globular protein.

Could a protein have what is called a globular shape?
Tritiory proteins are globular proteins. Every enzyme is a globular proteins.
What shape is the protein actin?
Actin is a globular molecule
What differences do hemoglobin and hair proteins have?
They have different structure types. Hemoglobin is a globular protein, where it has a globular shape from the folding of amino acids by the hydrophobic effect. alpha-Keratin (the protein in hair), on the other hand, has a helical structure, with a repeating pattern of amino acids. Hemoglobin does not have a continuous repeating pattern of amino acids.
What shape of a protein molecule resembles?
Protein molecules can have various shapes, such as globular, fibrous, or membrane-bound. The shape of a protein is important for its function, with globular proteins often being enzymes or transport molecules, and fibrous proteins providing structural support. Additionally, the shape of a protein is determined by its specific sequence of amino acids.
How is a hydrogen bond used in making a protein?
The bases of the various amino acids are hydrogen bonded in the secondary structure of protein synthesis. Alpha helices and beta sheets are formed. This is the step before the various R groups start bonding and folding the protein into a globular shape in the tertiary structure.

Globular or fibrous polypeptide chains are what type of protein 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.
What is meant by the term folding?
In biology, folding refers to the process by which a protein's linear amino acid sequence adopts a specific three-dimensional shape to carry out its function. This folding process is critical for the protein to be functional.
When globular protein has its hydrogen bonds broken it becomes?
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.
What is the significance of the protein terminus in the process of protein folding and function?
The protein terminus plays a crucial role in protein folding and function by influencing the structure and stability of the protein. It can affect how the protein interacts with other molecules and determines its overall shape and function. The terminus also helps in directing the folding process and can impact the protein's activity and localization within the cell.
The characteristic globular shape of a polypeptide is?
determined by its amino acid sequence and interactions between amino acid side chains. The folding of the polypeptide into a specific shape is influenced by factors such as hydrogen bonding, disulfide bridges, and hydrophobic interactions. This globular shape is essential for the proper functioning of proteins in cells.
