WitrynaThe sulfur atom of cysteine is involved in formation the sulfhydryl group which is very reactive. That differs cysteine from another sulfur amino acid - methionine which has a methyl group attached to the sulfur. Thus methionine is more hydrophobic, sterically larger and much less reactive than cysteine. Witryna1 cze 2006 · Methionine, cysteine, homocysteine, and taurine are the 4 common sulfur-containing amino acids, but only the first 2 are incorporated into proteins. Sulfur belongs to the same group in the periodic table as oxygen but is much less electronegative. This difference accounts for some of the distinctive properties of the …

"WitrynaThe sulfur-containing amino acids (cysteine and methionine) are generally considered to be nonpolar and hydrophobic. In fact, methionine is one of the most hydrophobic amino acids and is almost always found on the interior of proteins. Cysteine on the other hand does ionize to yield the thiolate anion. Even so, it is uncommon to find cysteine ... " - Is sulfhydryl hydrophobic
