A group of BS Biology students were tasked to design and fabricate different synthetic cell membranes that could be used to simulate cellular activities of certain organisms. Below are the chemical structures of the compounds that are available to them: H2C-OH НС — ОН HO H2C-OH myristic acid glycerol НО alpha-linolenic acid HO-P-o OH orthophosphate HO NH2 sphingosine OH CH2OH NH3 CH2OH HO ethanolamine HO OH OH OH Но. lactose ("point of attachment) Given these compounds, help the students assemble the structure of the lipid constituent for the cell membrane appropriate to study the following. Briefly explain your answer. (Draw the structure) а. a thermophilic bacteria thriving in a hot spring b. a hepatocyte of a sea lion in the Arctic Ocean С. a frog neurocyte
Electrophoresis is the movement of molecules within a matrix (paper, gel) to which an electric field is applied – from a central origin, a molecule with a net positive charge moves toward the negative pole (often called cathode) and a molecule with a net negative charge moves toward the positive pole (often called anode). for the pentapeptide: N – Lys - gly - asp - his - glu - C What is the net charge at pH 3? 2.What is the net charge at pH 11? 3. At pH 3 will the pentapeptide move to the negative pole, positive pole or not move? 4. At pH 11, the same question.
