Together their initial letters spell the word lah (or hal backwards). They are lysine, arginine, and histidine. Glycine’s small R-group being just a hydrogen allows proteins incorporating it to make very tight turns, giving the polypeptide chain a lot of flexibility to twist and turn. The three remaining amino acids all have alkaline radicals. Further, glycine is the only non-chiral amino acid because its alpha carbon is bonded to two identical hydrogens, creating an internal plane of symmetry. The nine amino acids that have hydrophobic side chains are glycine (Gly), alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), methionine (Met), and tryptophan (Trp). These 20 -amino acids can be sub-classified according to how the properties of other functional groups in the 'R' group influence the system. However, you can also project these structures on the walls of a Memory Palace. Hydrophobic Amino Acids Amino acids are grouped according to what their side chains are like. The means the main difference between the various amino acids lies in the structure of the 'R' group.

Glycine’s R-group is a single hydrogen atom, which makes it a non-polar, hydrophobic amino acid. How to Memorize An Amino Acid Fundamental Structure.

Summary Glycine, which is abbreviated as the 3 letters Gly as well as the single letter G, is one of the 20 amino acids that make up proteins in our body. In contrast the side chains of hydrophobic amino acids are free and most likely participate in dimerization of STAT3. Also important to tertiary structure are hydrophobic interactions, in which amino acids with nonpolar, hydrophobic R groups cluster together on the inside of the protein, leaving hydrophilic amino acids on the outside to interact with surrounding water molecules.
