Amino acids are soluble in water and fatty acids are not.
It really depends on the type of chromatography. E.g. with thin layer chromatography, UV light is used, and the amount of light that is absorbed is measured, and they can tell the amino acid from this. In paper chromatography, a substance called ninhydrin is sprayed onto the separated amino acids and they become visible.
Amino acids that cannot be made by metabolism are called essential amino acids. These amino acids must be obtained through diet.

Amino acids are the molecules. Dipeptide bonds is the specific name for the covalent bonds.

Two types of amino acid screening tests are used together to diagnose amino acid disorders.Blood plasma screening.Urine test.Both these tests use thin layer chromatography to separate the amino acids present.
A solution of amino acids is spotted onto a piece of chromatography paper which is then placed into a container filled with a suitable solvent. A dye is used so that the position of the amino acids along the piece of paper can be seen. The distances travelled by the amino acids are measured to calculate their retention factors (Rf) values. These are then compared to known standards.

Chromatography
some applications are; "Separations of inks, amino acids" from a mixture , blood and urine anlysis, from a mixture
The proportion of the amino acids are similar to those produced in the Miller-Urey experiment.
The monomers of proteins are amino acids.
They are the amino acids. They are the monomers
Amino acids held together by peptide bonds.
