Textbook Question
Chapter 19, Problem 19.38P
8 In Chapter 22, we will discuss a class of compounds called amino acids, so named because they contain both an amino group and a carboxyl group. Following is a structural formula for the amino
acid alanine.
What would you expect to be the major form of alanine present in aqueous solution (a) at pH 2.0, (b) at pH 5—6, and (c) at pH 11.0? Explain.

The amines are organic weak bases which are nitrogen-containing. In the early days of organic chemistry, basic amines derived from natural sources were known as “vegetable alkali”, but they are now referred to as alkaloids. The study of alkaloids provided much of the growth of organic chemistry, phytochemistry and natural products chemistry. It remains a fascinating area of research. Please search for one naturally occurring alkaloid and provide the following:
Name of the alkaloid and show its structure. Identify using arrows the polar bonds in the structure
