Our skin has soil which will affect the polarities of the substances affected by capillary action. Chromatography is used to determine the components of a mixture based on polarity. If the fair used to analyze the components is compromised accordingly we will alter our data and the result may not be accurate. 3. Where is the kitchen, or in the body, might one satisfy mixtures of amino acids?
