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.

∙ 8y agoAmino acids are distinguished by their R groups. There are 20 amino acids common to all life (examples being alanine, phenylalanine, glycine, tryptophan and aspartate). All consist of a central carbon atom attached to a hydrogen and a carboxylic acid group and an amino group. That is the same for all amino acids. The unique and differentiating feature of an amino acid is the R group or side chain. The R group is simply a hydrogen atom in the amino acid glycine. The R group is a methyl group in alanine. Phenylalanine is similar to alanine, but instead of the CH3 methyl group, one hydrogen is replaced with a phenyl group.

∙ 10y agoThe portion of the molecule that accounts for variations between amino acids is the "R' or 'radical'. The radical represents the difference in each amino acid.

What group makes up the amino part of the amino acid?
The amino group is present at one end of the amino acid and is represented by the chemical formula NH3 The region on the amino acid that contains the amino group is called the amino terminal
Is there a difference between the two?
Protein shakes are not the same as amino acid supplements. Amino acids will become proteins. Amino acid supplements and protein shakes are popular options.
How proteins differ?
Proteins differ each other in their amino acid composition and the number of amino acids that form it. Not all the proteins are the same, although they are all made up of amino acids. the sequence of amino acids is determined by the mRNA which is transcribed by DNA in the nucleus.
What type of chemical grouping present in all proteins?
A protein is any chain of amino acids. An amino acid is a small molecule that acts as the building block of any protein. If you ignore the fat, your body is about 20-percent protein by weight. It is about 60-percent water. Most of the rest of your body is composed of minerals (for example, calcium in your bones). Amino acids are called "amino acids" because they contain an amino group (NH2) and a carboxyl group (COOH) that is acidic. In the figure above, you can see the chemical structure of two of the amino acids. You can see that the top part of each one is the same. That is true of all amino acids -- the little chain at the bottom (the H or the CH3 in these two amino acids) is the only thing varying from one amino acid to the next. In some amino acids, the variable part can be quite large. The human body is constructed of 20 different amino acids (there are perhaps 100 different amino acids available in nature).
Is the amino group present in all amino acids?
no there r 20 different kinds of amino acids which differ from each other in chemical formula. all 20 amino acids have same NH2,H and COOH group, attached with C but they have different side chains due to which they are different in molecular formula..... Dr danial quddus.
Is amino acid is acid?
Amino acids are, as the name suggests, both amines (basic) and acids (acidic, of course). They fall into the category of compounds known as zwitterions: chemicals that have an acidic part and a basic part in the same molecule.
Amino acid funtional group?
Amino acids have both amine and carboxylic acid functional groups and are therefore both an acid and a base at the same time.
What group makes up the amino part of the amino acid?
The amino group is present at one end of the amino acid and is represented by the chemical formula NH3 The region on the amino acid that contains the amino group is called the amino terminal
How many human amino acids are the same as the chicken amino acids?
Amino acids are chemicals, it doesnt matter from which organism it is, they are chemically the same (for example Glycine is an amino acid, it is the same in any species).What will iffer is, the sequence of amino acids that make proteins (such as Glycine alanine valine tyrosine is a sequence may not be same like phenylalanine serine glutamine aspartate)

Whats the difference between an amino acid molecule and a protein molecule?
Amino acids make up proteins. Protein molecules are made of a long chain of three amino acids each linked to its neighbor through a covalent bond. Amino acids are compounds containing an amino group and a carboxylic acid group.
When the four DNA bases are combined in triplets different what of the protein are called for?
Amino Acids? I'm not positive but I'm working on the packet and have the same question.

What are the component of amino acid?
The 20 amino acids vary in structure by the R-group, otherwise all amino acids are the same in structure. All amino acids have a carboxyl group, an amino group, an R-group, and a hydrogen which are all bonded to a central carbon. It is the R-groups that make the amino acids react in different ways and alter the structure of the protein.
Are glycine and carboxylic acid th same?
No, glycine is one of many different carboxylic acids. Carboxylic acids come in a wide variety ranging from formic acid to amino acids (which include glycine) and fatty acids.
Is nucleic acids the same as amino acids?
No. Amino acids are monomers of proteins and nucleic acids is a macromolecule.
