What is the function of deiodinase?

Deiodinases are able to extract electrons from iodides, and iodides from iodothyronines. They are, thus, involved in thyroid-hormone regulation, participating in the protection of thyrocytes from damage by H 2 O 2 produced for thyroid-hormone biosynthesis.

What is selenide dianion Se2-?

The selenide dianion Se 2− forms a variety of compounds, including the minerals from which selenium is obtained commercially. Illustrative selenides include mercury selenide (HgSe), lead selenide (PbSe), zinc selenide (ZnSe), and copper indium gallium diselenide (Cu (Ga,In)Se 2 ).

What is the ISSN for selenium?

ISSN 2251-6085. PMC 6570790. PMID 31223567. ^ Selenium. Linus Pauling Institute at Oregon State University. Retrieved 2009-01-05.

What is iodotyrosine deiodinase?

Iodotyrosine deiodinase, also known as iodotyrosine dehalogenase 1, is a type of deiodinase enzyme that scavenges iodide by removing it from iodinated tyrosine residues in the thyroid gland.

What are deiodinases (Dio)?

Deiodinases (Dio) are selenocysteine-containing enzymes capable of removing iodide from iodothyronines (Bianco, Salvatore, Gereben, Berry, & Larsen, 2002). Deiodination is the most important metabolic pathway of thyroid hormones. It is catalyzed by enzymes that contain the amino acid selenocysteine in their active center.

How are deiodinases regulated by hormones?

The deiodinases are regulated by multiple hormones, growth factors, and environmental and nutritional factors. 41 Foremost among these are the thyroid hormones themselves; alterations in thyroid status induce profound changes in enzyme activity (Fig. 76-4).

What is the iissn for selenium pollution?

What are the 6 isotopes of selenium?

Isotopes of selenium. The chemical element selenium ( 34 Se) has six natural isotopes that occur in significant quantities, along with the trace isotope 79Se, which occurs in minute quantities in uranium ores. Five of these isotopes are stable: 74 Se, 76 Se, 77 Se, 78 Se, and 80 Se.

What is selenium?

Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between the elements on either side in the periodic table, sulfur and tellurium.

What is an ISSN number?

An International Standard Serial Number ( ISSN) is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is especially helpful in distinguishing between serials with the same title. ISSN are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature.
