Other Protein/Peptide Hormones

Hormones are chemical messengers produced by glands in the body to trigger physiological effects in specific cells, tissues, and organs. Hormones can be composed of peptides (short polymer sequences of amino acids) or proteins (longer sequences of amino acids).

The many glands of the body’s endocrine system secrete hormones into the bloodstream to help manage homeostasis and other conditions associated with the organism’s survival and reproduction. Calcitonin affects bones; Chorionic Gonadotropin is released during pregnancy; Glucagon and Insulin control blood glucose; Parathyroid Hormone (PTH) controls growth. Over- or under-production of any of these hormones can cause profound disease conditions.
Proteins and peptides offer numerous possibilities for drug development, research of new delivery methods, and the discovery of effective new therapeutic treatments for a wide range of disorders. Sigma-Aldrich offers protein and peptide products for research on numerous hormones and the affects they have on certain diseases.
