Choose an amino acid and model a system where this amino acid is used to generate a plasma membrane that is devoid of lipids and solely made of the chosen amino acid. Assume that all membrane proteins are present. Explain your choice of the amino acid and how would this hypothetical membrane be different form the actual plasma membrane.
Homework Answers
Chosen amino acid = Leucine
Reason: Leucine contains a polar head group (Amino and carboxyl groups) and a long nonpolar tail. It is similar to short chain fatty acids. It is an amphipathic molecule. So, it would form the bilayer. Polar heads face the aqueous environment while the nonpolar tails stack inside to form the bilayer.
Difference: Since Leu side chain is smaller than membrane fatty acids, the thickness of the membrane would be less.

QUESTION 42 The amino acid GABA is a commonly used neurotransmitter in the nervous system. If GABA were to bind directly to receptors and open chloride channels in an early developing neuron that had 100 mM chloride in the cytoplasm and 100 mM chloride in the extracellular fluid, the release of GABA from a presynaptic neuron would . hyperpolarize the post-synaptic cell and inhibit the production of action potentials in the post-synaptic cell lead to no change in the voltage...

Laboratory studies of protein synthesis often involve the addition of a radioactively labeled amino acid and natural or synthetic RNAs to cell extracts that provide the ribosomes, translation factors, tRNAs etc necessary for translation. Conversion of the labeled amino acid into protein is measured by precipitation using trichloroacetic acid (only proteins precipitate under these conditions). Conversion of amino acids into an acid-precipitable form is measured as a function of time to estimate the rate of protein formation.In the following experiment,...
