In addition, other kinds of proteins include&nbsp;[https://en.wikipedia.org/wiki/Antibodies antibodies]&nbsp;that protect an organism from infection, and&nbsp;[https://en.wikipedia.org/wiki/Hormones hormones]&nbsp;that send important signals throughout the body. The&nbsp;[https://en.wikipedia.org/wiki/Proteome proteome]&nbsp;is the entire set of proteins produced or modified by an organism or system. Proteomics enables the identification of ever-increasing numbers of proteins.
