secondary structure
This term is a specialized technical expression used primarily in biochemistry and molecular biology. It describes the folding patterns of a polypeptide or polynucleotide chain, specifically focusing on the repetitive patterns formed by hydrogen bonds. It is distinct from primary structure, which refers to the linear sequence of monomers, and tertiary structure, which refers to the overall three-dimensional fold.
In a professional scientific context, the term is almost always used to refer to specific motifs like alpha helices and beta sheets. Because it describes a structural category rather than a single object, it is typically treated as a countable noun when referring to different types of arrangements, though it can function as an uncountable concept when discussing the general phenomenon of folding.
Meanings
Examples
The alpha helix is a classic example of secondary structure.
I wonder if this mutation will disrupt the secondary structure of the protein.
Hydrogen bonds are essential for stabilizing the secondary structure.
The researcher analyzed the secondary structure using circular dichroism.
Does the secondary structure change when the temperature increases?
Beta sheets are another common form of secondary structure.
The RNA molecule folds into a complex secondary structure to function properly.
We need to determine the secondary structure before we can predict the tertiary fold.
