What term refers to the scientific study of the structure and function of proteins?

Proteomics refers to the comprehensive study of proteins, including their structure, function, and interactions within a biological system. This field aims to analyze the entire set of proteins expressed by an organism, providing insights into how proteins contribute to various cellular processes and biological functions. Proteomics is crucial for understanding disease mechanisms, developing new therapeutic strategies, and advancing the field of biotechnology.

The other terms do not pertain to the study of proteins. Protoplasm relates to the living content of a cell, psychiatry is a branch of medicine focused on diagnosing and treating mental health disorders, and psychology is the study of behavior and mental processes. Each of these areas addresses different aspects of science and health, distinct from the focus of proteomics.
