Endocrine Disruptors
Chemical compounds that interfere with hormone systems in living organisms, potentially causing developmental, reproductive, neurological, and immune system problems.
Endocrine Disruptors
Endocrine disruptors (EDs) are natural or synthetic chemicals that interfere with the endocrine system's normal functioning by mimicking, blocking, or altering hormone activity. These compounds represent a significant environmental and health concern due to their widespread presence in modern environments.
Mechanisms of Action
Endocrine disruptors operate through several key mechanisms:
-
Hormone Mimicry (molecular mimicry)
- Acting as hormone imposters
- Binding to hormone receptors
- Triggering unnatural responses
-
Hormone Blocking
- Preventing natural hormone binding
- Disrupting signal transduction
- Interfering with hormone production
-
Hormone Levels Alteration
- Affecting hormone synthesis
- Disrupting hormone transport
- Modifying hormone degradation
Common Sources
