a) which amino acid tested is most polar?
b) look up the structure of the amino acids. explain why it
makes sense that the amino acid you listed is more polar than the
others?
c) what amino acids are in the fruit juice?
D. CHROMATOGRAPHY Chromatography is a general technique that is used to separate various materials. In this case, students can use the unique chemistry of the amino acid to determine its migration in a specific solvent. The solutions...
D. CHROMATOGRAPHY Chromatography is a general technique that is used to separate various materials. In this case, students can use the unique chemistry of the amino acid to determine its migration in a specific solvent. The solutions of amino acids can be applied to the place and allowed to dry. The plate is placed in the solvent, and capillary action will carry the amino acids upward along the plate. The side chains, or R groups, can be characterized by their...

1.) Why is it that amino acids in proteins are called a-amino acids? 2.) explain alpha, amino, and acid . Please answer questions 1&2 !
3. A protein contains the following amino acids: O ALA 4 GLN 1 LEU 3 ARG 4 GLU 4 LYS 4 ASN 5 GLY O MET 1 ASP 1 HIS 2 PHE 4 ILE 4 PRO 8 SER 5 THR 1 TRP 2 TYR 2 VAL BGYS. a) What is its net charge at pH 1? b) What is its net charge at PH 13? c) Calculate the pl. 4. In what order would the amino acids GLU, LYS, and...
Constants ! Periodic Part A Explain why amino acids, unlike most amnines and carboxylic acids, are insoluble in diethyl ether. O An amino acid is insoluble in diethyl ether (a relatively nonpolar solvent), because an amino acid exists as a nonpolar molecule. In contrast, carboxylic acids and amines are more polar because they have a single charge depending on the extent of dissociation in diethyl ether An amino acid is insoluble in diethyl ether (a relatively nonpolar solvent), because an...
For the following amino acids - explain why the overall charge on the amino acid is different at PH's 2, 7, and 11. Relate it to the pk, of the groups on the molecules To achieve distinction, you must explain that the form of an amino acid, whether positively charged, negatively charged or neutral, depends on the pH of the solution and also on the Ka of the acid group
Answer the following two questions A paper chromatography experiment was conducted on a mixture of amino acids including Aspartic acid (Asp), Glutamic acid (Glu), Histidine (His), Leucine (Leu), Phenylalanine (Phe) and Proline (Pro). The following Rf values were determined: Asp (0.245), Glutamic (0.275), His (0.295), Leu (0.745), Phe (0.685) and Pro (0.445). In the experiment, a colored spot for unknown amino acid "W" was found centered at a distance 25 mm from the start line when the solvent line had...
what is the prediction of the unknown amino acids mixture
based on the strip from thin layer chromatography sheet?
The unknown mixtures can be ala plus asp, ala plus asp plus
lys, lys plus asp or ala plus lys.
anion exchange resin was used
Tubes 2,3, 6 and 7 had a spot appear that was light pink

1. When separating mixtures using TLC, why is it important to choose a solvent (mobile phase) that has a different polarity than the TLC plate (stationary phase)? 2. Why will some substances in a mixture travel farther up the TLC plate than others?
