Chapter 3. Amino Acids & Proteins Introduction to Molecular and Cell
Which Amino Acids Can Form Disulfide Bonds. Web amino acids are crystalline solids which usually are water soluble and only sparingly dissoluble in organic solvents. Disulfide bonds can be formed between cysteine residues within the same protein (intramolecular) or between proteins (intermolecular).

Their solubility depends on the size and nature of the side chain. Most disulfide linkages are found in proteins destined for export or residence on the plasma membrane. The a chain also contains an internal disulfide bond. Their other properties varying for each particular amino acid. They can also be formed between the cysteine residue of a protein and a thiol of a small molecular weight compound like glutathione. Web is cysteine the only amino acid that can form disulfide bonds? Thus methionine is more hydrophobic, sterically. Web we found that weakly hydrophilic and aromatic amino acids are quite abundant in the regions around disulfide bonds, contrary to aliphatic and hydrophobic amino acids. Two disulfide bonds connect the a and b chains together, and a. Web insulin consists of an a chain and a b chain.
Their solubility depends on the size and nature of the side chain. Web we found that weakly hydrophilic and aromatic amino acids are quite abundant in the regions around disulfide bonds, contrary to aliphatic and hydrophobic amino acids. Web cystine is composed of two cysteines linked by a disulfide bond (shown here in its neutral form). Disulfide bonds can be formed between cysteine residues within the same protein (intramolecular) or between proteins (intermolecular). The a chain also contains an internal disulfide bond. Two disulfide bonds connect the a and b chains together, and a. Their solubility depends on the size and nature of the side chain. Web the amino acid cysteine (cys) has a sulfhydryl (sh) group as a side chain. They can also be formed between the cysteine residue of a protein and a thiol of a small molecular weight compound like glutathione. Web the cysteine amino acid group is the only amino acid capable of forming disulfide bonds, and thus can only do so with other cysteine groups. Web insulin consists of an a chain and a b chain.
