Organic Chemistry
Give the structure of the tetrapeptide Ser-Cys-Met-Asp and highlight the peptide bonds in red to indicate them.
Show how D-leucine can be synthesized from the L enantiomer of leucic acid
Lysine Ketoglutarate Reductase(LRK)/ Saccharopine Dehydrogenase (SDH) acts as a catalyst in the metabolism of lysine. It catalyzes the condensation of lysine with a-ketoglutarate to produce saccharopine. and degradation of saccharopine into glutamate. Propose a structure for saccharopine.
Draw the three-dimensional structure of L-glutamic acid.
Draw a structure of phenylthiohydantoin derivative of serine that is formed from the Edman degradation reaction.
