Is the r group the side chain

Witryna16 cze 2024 · The variation of the R group side chains alters the chemistry of the amino acid molecule. Most amino acids have side chains that are non-polar (do not have positive and negative poles). Others have positively or negatively charged side chains. Some have polar side chains that are uncharged. WitrynaSo the 20 amino acids can be split broadly into kind of two main groups. The first group includes the nonpolar amino acids, and then the second group includes the polar …
