Disulfide bonds are covalent bonds between S atoms of amino acid R groups of separate amino acids in the same protein.
True or False
Homework Answers
Disulfide bonds are covalent
bonds between S atoms of amino acid R groups of separate amino
acids in the same protein. Here (as shown above) S atoms from two
separate amino acid's R group forms disulfude linkage among one
protein chain.
Hense this statement is True.
Add Answer to:
Disulfide bonds are covalent bonds between S atoms of amino acid
R groups of separate amino...
Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids
Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and quaternary Question Is the following statement true? If not, explain why not: Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids (a hydrogen on an amide N on one amino acid interacts with an oxygen on the carbonyl of another amino acid), the secondary structure does not depend on the specific amino acid groups (the R-groups) in the amino acid chain. Select...

Which of the following is NOT true about disulfide bonds? Disulfide bonds form between two sulfur atoms. The formation of a disulfide bond is an oxidation reaction. The terms disulfide bonds and disulfide bridges are used interchangeably. Disulfide bonds determine the three dimensional conformation of a protein.
