Are parallel or antiparallel beta sheets stronger in protein structures?

Antiparallel beta sheets are generally stronger in protein structures compared to parallel beta sheets.


Why protein is called primary structure?

Proteins *have* primary, secondary, tertiary, and quarternary structures. The primary structure is simply the chain of amino acids without any other structure. Secondary structure results from folding of the chain to form rudimentary structures such as alpha helices, beta sheets and turns. Tertiary structure results from the further folding of the protein with secondary structures into different 3D shapes by interactions between different parts of the secondary structure. Quarternary structure results from different proteins with tertiary structures coming together to form a protein complex.


Which amino acid can stabilize protein structures by forming covalent cross-link between polypeptide chains?

Cysteine is the amino acid that can stabilize protein structures by forming covalent cross-links between polypeptide chains through disulfide bonds.


Which levels of structural organization are lost when a protein is denatured?

When a protein is denatured, it typically loses its secondary, tertiary, and quaternary structures. This results in the disruption of its folded conformation and can lead to loss of function. The primary structure (sequence of amino acids) usually remains intact unless extreme denaturing conditions are applied.


What is the significance of the glycine and alanine dipeptide in protein structure and function?

The glycine and alanine dipeptide play a significant role in protein structure and function. Glycine is the smallest amino acid and its flexibility allows for tight turns in protein structures. Alanine is a non-polar amino acid that helps stabilize protein structures. Together, they contribute to the overall stability and flexibility of proteins, influencing their function in various biological processes.

What is the role of secondary protein structures in determining the overall function of a protein?

Secondary protein structures, such as alpha helices and beta sheets, play a crucial role in determining the overall function of a protein. These structures help proteins fold into specific shapes, which are essential for their function. The arrangement of these structures can affect how proteins interact with other molecules and carry out their biological roles.

Why is meat protein good for you?

Protein is needed by the body to grow and repair itself. Meat has the highest concentrations of complete protein in the world of food. Individual vegetable proteins are incomplete and so vegetables must be combined with other vegetables to create complete protein structures. Meats offer complete proteins.
