Miller’s experiment was conducted to simulate the conditions of early Earth and to investigate the possibility of the formation of organic molecules, including amino acids. The experiment involved subjecting a mixture of gases, such as methane, ammonia, water vapor, and hydrogen, to electric sparks to create a range of organic compounds.

The amino acids that were found to be synthesized in Miller’s experiment were glycine, alanine, aspartic acid, and several others. However, glutamic acid was not found to be synthesized in Miller’s experiment.

Explanation:
Glutamic acid is a non-essential amino acid that plays a crucial role in various metabolic processes. It is found in most proteins and is important for the proper functioning of the nervous system. Despite its importance, glutamic acid was not detected in Miller’s experiment.

There are several possible reasons for this, including:

- Glutamic acid is a more complex amino acid than the ones that were detected in Miller’s experiment. It contains an additional carboxylic acid group, which may make it more difficult to synthesize under the experimental conditions.
- The conditions of Miller’s experiment may not have been suitable for the synthesis of glutamic acid. For example, the concentration of certain gases or the temperature of the experiment may not have been optimal for the synthesis of this amino acid.
- The detection methods used in Miller’s experiment may not have been sensitive enough to detect low levels of glutamic acid. It is possible that this amino acid was synthesized but in very small quantities that were not detected by the analytical techniques used in the experiment.

In conclusion, while Miller’s experiment was successful in demonstrating the possibility of the formation of amino acids under early Earth-like conditions, it did not synthesize all the amino acids found in living organisms. Glutamic acid, a non-essential amino acid, was not detected in the experiment.
