Which components of paprika move up the plate the most in a TLC experiment? Use polarity. The components are Capsanthin, capsorbin and beta carotene.

Solutions

Expert Solution

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
