α-Amanitin Bacitracin Ciclosporin. Cyclic peptides are polypeptide chains which contain a circular sequence of bonds. [1] This can be through a connection between the amino and carboxyl ends of the peptide, for example in cyclosporin; a connection between the amino end and a side chain, for example in bacitracin; the carboxyl end and a side chain, for example in colistin; or two side chains ...
Enterohepatic circulation of drugs. Enterohepatic circulation is the circulation of biliary acids, bilirubin, drugs or other substances from the liver to the bile, followed by entry into the small intestine, absorption by the enterocyte and transport back to the liver.
[5]: 572 To the right is an illustration of the amphibolic properties of the TCA cycle. The glyoxylate shunt pathway is an alternative to the tricarboxylic acid (TCA) cycle, for it redirects the pathway of TCA to prevent full oxidation of carbon compounds, and to preserve high energy carbon sources as future energy sources. This pathway occurs ...
Hepcidin, a peptide hormone that regulates iron homeostasis. Insulin-like growth factor 1, a polypeptide protein hormone which plays an important role in childhood growth and continues to have anabolic effects in adults; Thrombopoietin, a glycoprotein hormone that regulates the production of platelets by the bone marrow

Peptides are amino acids − the body's building blocks of protein. Understand why athletes use them to get a leg up. ... Other peptides affect one's endocrine system, which plays an important ...
In a cAMP-dependent pathway, the activated G s alpha subunit binds to and activates an enzyme called adenylyl cyclase, which, in turn, catalyzes the conversion of ATP into cyclic adenosine monophosphate (cAMP). [5] Increases in concentration of the second messenger cAMP may lead to the activation of cyclic nucleotide-gated ion channels [6]
The stunting effect of kalata B1 cyclic peptide on growth and development of Helicoverpa punctigera, a caterpillar from the Lepidopteran order. [6]Cyclotides have been reported to have a wide range of biological activities, including anti-HIV, insecticidal, anti-tumour, antifouling, anti-microbial, hemolytic, neurotensin antagonism, trypsin inhibition, and uterotonic activities.
