Neutral Amino Acids

Amino acids which do not have any charge on them are neutral amino acids.

Globular Protein

The globular proteins refer to the shape of protein specifically spherical in nature apart from spherical form fibrous, disordered and membrane-bound proteins exist. These globular proteins are miscible in water and form a colloidal solution rather than …

Dimer

Dimers are basic organic compounds, which are derivates of oligomers. It is formed by the combination of two monomers which could potentially be strong or weak and in most cases covalent or intermolecular in nature. Identical monomers are called homodime…

Dipeptide

A dipeptide is considered a mixture of two distinct amino acids. Since the amino acids are distinct, based on their composition, two dipeptide's isomers can be produced. Various dipeptides are biologically essential and are therefore crucial to industry.

Textbook Question

Chapter 2.10, Problem 43P

A naturally occurring amino acid such as alanine has a group that is a carboxylic acid and a group that is a protonated amine. The pK_a, values of the two groups are shown.

Chapter 2.10, Problem 43P, A naturally occurring amino acid such as alanine has a group that is a carboxylic acid and a group

a. If the pK_a value of a carboxylic add such as acetic acid is about 5 (see Table 2.1 ), then why is the pK_a value of the carboxylic acid group of alanine so much lower?
b. Draw the structure of alanine in a solution at pH = 0.
c. Draw the structure of alanine in a solution at physiological pH (pH 7.4).
d. Draw the structure of alanine in a solution at pH = 12.
e. Is there a pH at which alanine is uncharged (that is. neither group has a charge)?
f. At what pH does alanine have no net charge (that is, the amount of negative charge is the same as the amount of positive charge)?

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
