How can you determine the purity of amino acid using paper chromatography?
To determine the purity of an amino acid using paper chromatography, you would first need to separate the amino acids using paper chromatography. Once the amino acids are separated on the paper, you can calculate the Rf value (retention factor) for each amino acid. Comparing the Rf values of the sample amino acid to a standard of known purity can help determine the purity of the sample.
Would RF values of amino acid you use in paper chromatography be the same if you use another solvent system?
No, RF values depend on the specific solvent system used in the chromatography process. Changing the solvent system can alter the interactions between the amino acids and the stationary phase, resulting in different RF values. It is important to optimize the solvent system to achieve accurate and reproducible results.
How can proteins be analyzed by chromatography?
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.
How do you identify amino acids on a chromatography?
Amino acids can be identified on chromatography by using techniques such as thin-layer chromatography (TLC) or high-performance liquid chromatography (HPLC). After applying the sample to the chromatography medium, the mixture is separated based on the amino acids' different affinities for the stationary phase and the mobile phase. Visualization methods, such as UV light or specific staining solutions, help reveal the separated amino acids as distinct spots or peaks. Comparing the retention factors (Rf values) or peak characteristics to known standards allows for their identification.
Proteins are formed of building blocks called?
Amino acids held together by peptide bonds.

How can one calculate the pi value of amino acids?
To calculate the pI (isoelectric point) value of amino acids, you can use their pKa values. The pI is the pH at which an amino acid carries no net charge. For amino acids with a basic side chain, the pI is the average of the pKa values of the amino and carboxyl groups. For amino acids with an acidic side chain, the pI is the average of the pKa values of the carboxyl and side chain groups.
Where you could find the standard Rf values for fatty acids and poly unsaturated fatty acids?
You can typically find standard Rf values for fatty acids and polyunsaturated fatty acids in scientific literature, such as research papers, textbooks on chromatography, or chemical databases like ChemSpider or PubChem. These values may vary depending on the specific method and conditions used for their determination.
How can one calculate the pi of amino acids?
To calculate the pI (isoelectric point) of amino acids, you can use their pKa values. The pI is the pH at which an amino acid carries no net charge. For amino acids with acidic and basic groups, the pI is the average of the pKa values of the ionizable groups. You can use a formula or online tools to calculate the pI of amino acids.
Proteins are formed of building blocks called?
Amino acids held together by peptide bonds.
Proteins are made up of monomers called?
Proteins are made up of monomers called amino acids.
Do all amino acids have a pKR?
No, most of the R-groups of the 20 standard amino acids have strong bonds that do not allow them to be ionizable. All charged amino acids are ionizable (positive and negative) but only Cys and Tyr have pKRs for the rest.
