The exact 3D structure of a purified protein can be determined by __________ and ____________.
举一反三
- _______________ determines the exact mass of every peptide fragment in a purified protein, which then allows the protein to be identified from a database that contains a list of every protein thought to be encoded by the genome of the organism in question.
- The β-sheet conformation of a protein can be considered an example of（） A: Primary structure B: Secondary structure C: Tertiary structure D: Quaternary structure
- Protein folding has been studied in the laboratory using highly purified proteins. A protein can be unfolded, or denatured, by treatment with _______ that disrupt the noncovalent interactions holding the folded chain together.
- A part of protein sequence that can form a compact three-dimensional structure and often can be independently folded is called ______.
- β-turns in protein molecules belong to the protein's hierarchical structure? A: Primary structure B: Secondary structure C: Tertiary structure D: Side chain conformation
