proteome

A proteome is the complete set of proteins that an organism, cell, or biological sample produces at a given time. Proteins are essential molecules that perform most of the functions necessary for life, such as building structures, enabling chemical reactions, and signaling. The proteome varies between organisms and even within a single organism depending on factors like development and environment. Studying the proteome helps scientists understand how biological processes work and how they change in health and disease. Unlike genes, which are static, the proteome is dynamic and reflects the current state of the organism.
