Proteins Peptides Specifications
Type
Primary Structure:
The sequence of amino acids in a peptide chain, determined by genetic coding.
Secondary Structure:
Local folding patterns within the peptide, such as alpha helices and beta sheets, stabilized by hydrogen bonds.
Tertiary Structure:
The overall three-dimensional shape of the peptide, including interactions between secondary structural elements.
Quaternary Structure:
When peptides interact with each other to form larger complexes, such as in some multi-subunit proteins.
