Biomolecules: Amino Acids, Peptides, and Proteins
Proteins and peptides are large biomolecules made of α -amino acid residues linked together by amide, or peptide, bonds.
Practice this chapterProteins and peptides are large biomolecules made of α -amino acid residues linked together by amide, or peptide, bonds. Determining the structure of a peptide or protein begins with amino acid analysis.
The peptide is hydrolyzed to its constituent α -amino acids, which are separated and identified. Edman degradation by treatment with phenyl isothiocyanate (PITC) cleaves one residue from the N terminus of the peptide and forms an easily identifiable phenylthiohydantoin (PTH) derivative of the N-terminal amino acid .
peptide — hydrolyzed to its constituent α -amino acids, which are separated and identified.
Worked example
What does “peptide” mean in Biomolecules: Amino Acids, Peptides, and Proteins?
- 1Use the wording this chapter gives for peptide.
- 2The book says: hydrolyzed to its constituent α -amino acids, which are separated and identified.
- 3Keep the answer tied to this term.
Result: hydrolyzed to its constituent α -amino acids, which are separated and identified
Why. That is the meaning this chapter gives for peptide.
Answer with the meaning this chapter gives. A nearby idea from the same book is a different term.
