f the paper chromatography can be seen in Calculations Use the ruler located at the right side of the paper chromatography to calculate the R value for each amino aid in each sample Show your work below Solvent front Start line 2 What is the purpose of spraying the paper with a 0 5 solution of ninhydrin 3 Based on your calculations what amino acids are in samples 1 3 Bacterial Species E coli S aureus Sagalactiae Sample 11 Sample 2 Analysis 1 Referring to the procedure what is the purpose of exposing the dipeptide samples to a 6N HCI solution Sample 3 Medium Composition 70 arginine 20 glutamine 10 threonine 50 valine 10 alanine 40 scrine 60 glutamic acid 10 valine 30 leucine Figure 2 Developed paper chromatography 4 Once you have determined the amino acid composition of each sample you are told that each sample was taken from a specific species of bacteria The dipeptide samples represent the amino acids that are most important to the bacteria s survival and reproduction You are not told which sample represents which bacteria but you are given the amino acid composition of the medium that each bacteria grows best in Medium is a solution of nutrients that allow bacteria to survive and reproduce in a lab Use the table below to determine the species of bacteria that each sample represents
