QUESTION 18 (12.10) Shown here is the amino acid glycine at a pH of H3N-CH2-C-O 14...
Incorrect Question 16 0/1 pts This amino acid is +H3N—CH-0-0 CH2 CEO neutral aspartic acid. aspartic acid at its isoelectric point. aspartic acid at a pH that is lower than the isoelectric point. aspartic acid at a pH that is higher than the isoelectric point. Reconsider your answer! Since the nitrogen atom has a positive charge and both carboxylic acid groups have lost a hydrogen atom, this amino acid must be at its isoelectric point.
Classify the amino acid shown here. A) acidic H3N+ B) basic C) nonpolar D) neutral HN E) hydrophobic Which of the following molecules contains an amino group? A B OH NH2 A) A OH B) B C) C NH2 DD Which of the following molecules is a aldehyde? A B i H A) A B) B C) C i FO OH DD

Glycine is the simplest of the amino acids, has the formula, CH2 (NH2) COOH and the Lewis structure.a. Write the VSEPR formula for the nitrogen atom as the central atom in glycine.b. Based on VSEPR theory, what is the approximate C-N-H bond angle in glycine? Explain.c. What is the approximate O-C-O bond angle in glycine? Explain.d. Identify at least two absorption bands ( and corresponding cm-1) that would likely appear in the infrared spectrum of glycine.
