All amino acids have an acidic group (--COOH) and an amino group (H2N--), each linked to a central carbon by a separate covalent bond. They differ by the R group (remainder group) attached to the central carbon atom. (Source: Inquiry Into Life by Sylvia S. Mader)
R-groups
What? Speak proper english, please. The main difference between amino acids and what?
They are made od amino-acids. In chemistry, an amino acid is a molecule that contains both amine and carboxyl functional groups. In biochemistry, this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent. Alpha-amino acids are the building blocks of proteins.

Once the original DNA has been unzipped and the mrna has made a complementary copy it is time for the trna to do its work. The mrna moves out of the nucleus and moves into the rrna where the trna come with certain group of 3 nucleotides which codes for a specific amino acid. When the bases on the trna and the ones on the mrna are matched it drops of its amino acid to the trna behind it which forms a peptide bond with the other amino acids.(The rrna has 3 slots where the trna sit and deposit their amino acid to the one behind in line to them.) After the mrna has fully been decoded into amino acids their chain breaks off to make a protein in the secondary, tertiary, or quaternary structure.
DNA nucleotides 'code' for RNA copies of the DNA strand, but the true 'coding' of nucleotides happen in the ribosome where amino acids are matched to the RNA nucleotides. Nucleotides in DNA are only are present to store genetic data. When a particular gene needs to be used or a protein needs to be made, a RNA copy of the DNA will be made, using the slightly different RNA nucleotides (adenine, uracil, cytosine and guanine). This copy then leaves the nucleus and travels to the ribosome, where the RNA nucleotides are used to assemble amino acids into proteins. Each amino acid matches up to a three-nucleotide sequence.

The side chain. Each proteinogenic amino acid has a hydrogen, a carboxylic acid, and an amine group on a central carbon, with a side chain that varies between the acids.
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.

No,fatty acids don't have an amino group
The amino acids vary in the side groups, usually designated by "R" on the chemical structures for amino acids. The invariant parts are the amino group (NH2-), central (-CH-) group, and the carboxyl (-COOH) group. Connected to the central carbon on the (-CH-) group is a side group which is part that varies.
Amino acids differ according to their R groups. All amino acids have an amino group, a carboxyl group (organic acid), and a hydrogen atom attached to a central carbon atom. Also attached to the central carbon atom is an R group that varies according to the amino acid. Refer to the related links for illustrations.

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 reaction between two amino acids by elemination of small group like (H2O or NH3)
A peptide bond is a covalent bond formed between two amino acids in a protein. It links the carboxylic group of one amino acid to the amine group of the other.
