R groups can be polar or nonpolar. Amino acids can be called aliphatic amino acids or aromatic acids if the R group is aliphatic or aromatic respectively. Amino acids can be classified on their solubility in water, if the R group is hydrophilic then the amino acid is water-soluble, or if...
The chemical nature of the side chain determines the amino acid's nature (that is, whether it is acidic, basic, polar, or nonpolar). For example, the amino acid glycine has a hydrogen atom as the R group. Amino acids such as valine, methionine, and alanine are nonpolar or hydrop...
The rest of the molecule is in most cases the primary portion of the amino acid and determines the identity of the amino acid itself as well as whether the amino acid is polar or nonpolar. As stated, almost all α-amino acids are chiral, meaning that two arrangements of the same ...
The mutational exchange of a polar group for a non-polar one and vice versa must be more dangerous than the transition from one polar group to another or from a non-polar to another non-polar one. The well-known example is the transition from Glu to Val in the case of sickle-cell ...
Amino acids can be classified into four categories – polar, nonpolar, positively charged, or negatively charged - depending on the properties of the “R” group in each amino acid. Polar amino acids have a hydrophilic “R” group that seeks contact with water and aqueous solutions. Cysteine,...
Amino acids can be classified into four general groups based on the properties of the "R" group in each amino acid. Amino acids can be polar, nonpolar, positively charged, or negatively charged. Polar amino acids have "R" groups that arehydrophilic, meaning that they seek contact with aqueou...
The interaction of anion with the surface is weakened if anion of AAIL contains polar group. Responsing with lower potential is an important factor in using an IL as an electrolyte in supercapacitors. Polar group decreases the response potential of the AAIL....

aAnalogues of polar serine (methanol) and nonpolar alanine (methane) were constructed by replacing the backbone part of each amino acid with a hydrogen and adjusting the adjacent atom type to achieve neutrality. 极性丝氨酸(甲醇)和无极的胺基代丙酸(甲烷)类似物通过替换每氨基酸的中坚零件用氢和调整毗邻...
