Bimodal distributions for tyrosine. (a) The C[epsilon]—Cζ—Oη angle distributions involving the tyrosine alcohol have maxima at 120 (2)°. (b) A scatter plot of the C[epsilon]2—Cζ—Oη angle against the C[epsilon]1—Cζ—Oη angle confirms that the Cζ—Oη bond projects asymmetrically away from the aromatic ring.
