CH3
The -r group of alanine is -CH3 - which is a non-polar group, while the -r group of glycine is -H - which is an uncharged polar r group.
All amino acids consist of a central carbon atom bound to a caboxyl group, an amine group, a single hydrogen and one other molecule term the r group. It is this r group that varies between different amino acids. In alanine the r group is a methyl group (-CH3) and in glycine the r group is simply another hydrogen molecule.
The "R" group is different in different kinds of amino acids. The "R" group can be a number of different molecules that are attached to the alpha carbon.
An alanine is a nonessential amino acid found in most animal proteins, or a specific residue, molecule, or isomer of this amino acid.
Carboxylic acid group (-COOH) and amine group (-NH2) are in proteins. All amino acids are having these functional group with its specific prosthetic group. For example Glycine and Alanine will be the same structure except the side chain H in case of glycine and CH3 in case of alanine.
The -r group of alanine is -CH3 - which is a non-polar group, while the -r group of glycine is -H - which is an uncharged polar r group.
An R group is the chemical group attached to the alpha carbon in an amino acid. In proteins all amino acids have the same basic structure and vary only in their R group. There are 20 standard amino acids found in proteins, which all have different R groups. For example an amino acids with Hydrogen from its R group is glycine, and one carbon with 3 hydrogens (a methyl group) is the R group for alanine.
Alanine
All amino acids consist of a central carbon atom bound to a caboxyl group, an amine group, a single hydrogen and one other molecule term the r group. It is this r group that varies between different amino acids. In alanine the r group is a methyl group (-CH3) and in glycine the r group is simply another hydrogen molecule.
The "R" group is different in different kinds of amino acids. The "R" group can be a number of different molecules that are attached to the alpha carbon.
The r group found in amino acids consists of additional atoms.
Generally amino acids have an Amino group (-NH2) and a Carboxyl group (-COOH) attached to the same carbon atom, which is also called as Alpha carbon. Besides Hydrogen and R-Group is also attached with this carbon atom. R may be hydrogen, CH3 or any other group. For Example:If R-group is hydrogen then it is called glycine or if it is CH3 then it is called alanine.

By forming chemical bonds with two hydrogen atoms and a carbon atom, the nitrogen atom now the R group, and the hydrogen atom are all bonded to a central carbon atom (circled). They include alanine, valine, leucine and isoleucine.
Thiols.
R-COOH An R group bonded to a carbon that is double bonded to one oxygen and bonded singly to a hydroxyl group.
