Disulfide bonds between cysteine amino acids in a peptide chain are critically in stabilizing preferred secondary and tertiary structures. Many enzyme activities rely on specific shapes that are stabilized by these disulfide bonds.

Disulfide bonds in a protein chain connect what?
Could depend on what your options are but out of my multiple choice answers this was the best:two cysteine residues.
What is the term used for a change in a protein's three dimensional shape or confirmation due to disruption oh hydrogen bonds disulfide bridges or ionic bonds?
The change in a proteins' three dimensional shape or conformation is called denaturation.
What is the role of 2- mercapto ethanol in RNA extraction?
"b -mercaptoethanol is used to help to destroy RNases that may be present and will degrade the RNA. b -mercaptoethanol is a reducing agent that will reduce the disulfide bonds of the RNases, thereby destroying the conformation and the functionality of the enzyme". It comes from http://www.norgenbiotek.com/index.php?id=faqs_rnakits
What is a disulfide bond?
SH-SH
Disulfide bridges are found in what level of protein confirmation?
Tertiary
What functional group disulfide bonds?
The functional groups involved in forming disulfide bonds are sulfhydral (-SH) groups.
What functional groups form disulfide bonds?
The functional groups involved in forming disulfide bonds are sulfhydral (-SH) groups.
The antibody molecules is held together by what bonds?
Disulfide bonds
Is a Disulfide Bridge the same as Covalent Bond?
A disulfide bridge involves covalent bonds
What are the three diferentes types of side bonds?
Side bonds link two adjacent chains of atoms in a molecule. The three types of side bonds are hydrogen bonds, salt bonds and disulfide bonds.
Which amino acid contains sulfur atoms that form covalent disulfide bonds in its tertiary structure?
Cysteine forms disulfide bonds
How many disulfide bonds does insulin have?
3
What are the 3 side bonds that concern cosmetologists?
salt , hydrogen , and disulfide bonds
Can Heavy metals may also disrupt disulfide bonds because of their high affinity and attraction for sulfur and will also lead to the denaturation of proteins?
Yes, heavy metals insert themselves between disulfide bonds and this can cause denaturation of quaternary and tertiary protein structures.
What is lanthionization?
Lanthionization is the process by which hydroxide relaxers permanently straighten hair. It breaks the hair's disulfide bonds during processing and converts them to lanthionine bonds when the relaxer is rinsed from the hair. Disulfide bonds contain two sulfur atoms. Lanthionine bonds contain only sulfur atom. The disulfide bonds that are broken by hydroxide relaxers are broken permanently and can never be re-formed.
What are the three types of chemical bonds that cross-link protein strands in your hair?
Salt bonds, hydrogen bonds, disulfide bonds
What type of bond can two cysteine form?
Disulfide bonds
