The endocrine system orchestrates major developmental, reproductive, and other physiological changes throughout life. A detailed analysis of hormone suites can provide a better understanding of endocrine health, diseases, and disruptions.
Steroid hormones are signaling molecules that are major regulators of development, reproduction, stress, and growth. Steroids are synthesized from cholesterol through a series of enzymes, resulting in hormones with distinct biological activities. Although hormones are similar in structure, and therefore difficult to distinguish, they work in concert to produce a myriad of physiological responses.
Analytical methods for hormone suites are under development to better understand and monitor endocrine regulation. NIST scientists have developed mass spectrometry methods for the simultaneous measurement of multiple steroid hormones. Applications to samples from humans, wildlife, and agricultural stocks facilitate biomarker discovery for medical diagnostics, environmental exposure, and agriculture.
