<u>Proteomics</u> is a discipline of study that involves an examination of proteins and how the proteins encoded by genes interact to produce cell and tissue types.
What is Proteomics?
The extensive study of proteomes is known as proteomics. An organism, system, or biological setting produces a set of proteins known as a proteome. We might speak of an organ or a species' proteome (like that of Homo sapiens) (for example, the liver). The proteome is dynamic; it varies from cell to cell and alterations occur over time. The underlying transcriptome is somewhat reflected in the proteome. However, in addition to the relevant gene's expression level, a number of other factors also affect protein activity, which is frequently measured by the rate at which the processes in which the protein is engaged react.
Proteomics is employed to look into:
When and where do proteins expressed.
rates of protein synthesis, degradation, and abundance at steady state.
how proteins are altered, for as by phosphorylation and other post-translational modifications (PTMs).
the transfer of proteins among subcellular spaces.
protein involvement in metabolic processes.
what interactions proteins have with one another.

When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle. Denitrification - Extra nitrogen in the soil gets put back out into the air.
