Get started for freeGlutamic acid is synthesized by the following reaction sequence. Draw a stepwise mechanism for Steps [1]–[3].
After the peptide chain of collage has been formed, many of the proline residues are hydroxylated on one of the ring carbon atoms. Why is this process important for the triple helix of collagen?
Question: Identify A and B, isomers of molecular formula \({{\bf{C}}_{\bf{3}}}{{\bf{H}}_{\bf{4}}}{\bf{C}}{{\bf{l}}_{\bf{2}}}\), from the given \({}^{\bf{1}}{\bf{H}}\)NMR data: Compound A exhibits signals at 1.75 (doublet, 3H,\({\bf{J = 6}}{\bf{.9 Hz}}\)) and 5.89 (quartet, \({}^{\bf{1}}{\bf{H}}\),\({\bf{J = 6}}{\bf{.9 Hz}}\)) ppm. Compound B exhibits signals at 4.16 (singlet, 2 H), 5.42 (doublet, \({}^{\bf{1}}{\bf{H}}\),\({\bf{J = 1}}{\bf{.9 Hz}}\)), and 5.59 (doublet, \({}^{\bf{1}}{\bf{H}}\), \({\bf{J = 1}}{\bf{.9 Hz}}\)) ppm.
