is threonine prefer to adopt beta strand or helical conformation

Answer 1

Threonine can adopt both β-strand and helical conformations depending on its position in a protein sequence and its interactions with other amino acids.

In a β-strand conformation, threonine can be situated within the chain and participate in hydrogen bonding with neighboring amino acids. This allows the chain to form a β-sheet structure, in which strands align side by side.

In a helical conformation, threonine can be part of an α-helix structure, where it can interact with other amino acids through hydrogen bonding within the helical backbone.

Therefore, threonine can adopt both β-strand and helical conformations depending on the specific protein structure and its interactions within the protein sequence.
