Which components of paprika move up the plate the most in a TLC experiment? Use polarity. The components are Capsanthin, capsorbin and beta carotene.
paprika components:
- Capsanthin
- capsorbin
- beta carotene
for the MOST movement, if we use a TLC which has a stationary phase (POLAR) then, expec the least polar component to go the furtherst
This is mainly due to the fact of the interacitons between:
polar - polar
polar - nonpolar interactions
Identify which is the LEAST polar:
capsorbin = OH groups, C=O group, plenty of double bonds, CH3, slightly polar
Capsanthin = OH gtoups, C=O roups, cyclogroups, therefore, slightly oplar
beta-Carotene = most nonpolar, only C-H interactions
Therefore, from the list
expect beta-carotene to go the highest in the plate
