Protein Modifications

Protein modifications are changes that occur to proteins after they are made, altering their structure and function. These modifications, such as adding chemical groups or removing parts, help proteins perform specific tasks, adapt to different conditions, or regulate their activity. Common types include phosphorylation (adding a phosphate group), glycosylation (adding sugar molecules), and acetylation (adding an acetyl group). These processes are essential for proper cell function, communication, and response to signals. Think of protein modifications as fine-tuning mechanisms that ensure proteins work correctly and efficiently within the body.
