Question

You are observing proteins in a lab for an experiment. During transport, they have started to unwind and lose their shape.You notice long strands wound into alpha helices. What level of structure are the proteins in?

Answer 1

The level of the structure is the proteins in the secondary.

What is the structure of secondary?

• A polypeptide chain's adjacent amino acid residues are arranged in regular patterns in space, known as secondary structure. It is kept in place by hydrogen bonds between the amide hydrogens and the peptide backbone's carbonyl oxygens. Helixes and structures are the two main secondary structures.
• Local regions of proteins can be organized into one of three three-dimensional configurations: alpha helices (-helix), beta sheets (-strand), or omega loops. The alpha helix is the most prevalent secondary protein shape because it is stable and low-energy.
• The interaction of amino acids with every backbone NH hydrogen bound with the backbone C=O group of the corresponding amino acid residue in the polypeptide chain results in the- helix formation. The- helix motif is particularly prevalent in transmembrane regions of proteins that traverse the lipid bilayer.
