Sentences with phrase «iodine atoms»
Iodine atoms refers to individual particles of the chemical element iodine. Iodine is a type of atom that is often found in nature and used in various products such as medicine or to purify water. Full definition
The simulations determined that the central iodine atom is positively charged, even though the ion has a negative charge.

In fact, the hormones T3 and T4 are actually named due to this mineral: the numbers 3 and 4 indicate how many iodine atoms are bonded to the hormone.
The diiodine molecule, I2, is composed of two iodine atoms joined by a covalent bond.
The number «4» or «3» refers to the number of iodine atoms attached to the tyrosine.
This stimulated vibrations in the iodine molecules, which consist of two iodine atoms connected via a chemical bond (top left).
They then used a special arrangement of lasers to ensure that the particles all took up the same pose for the photo — like the members of a ballet ensemble — so that all of the benzene rings had the two iodine atoms aligned at their top and bottom.
In this way, the researchers were able to determine that the distance between the two iodine atoms on the benzene ring was 800 picometres (800 billionths of a millimetre), which is in good agreement with the actual value of 700 picometres known from theory.
The team tried several variations of the mixture, changing the number of carbon nanorings, and found that 10 rings led to the most dynamic iodine atom movement and the most sensitive response to external environmental changes.
While iodate is huge and surrounded by negative oxygen atoms, its central iodine atom takes on a positive character, or becomes a cation.
The «T» refers to the amino acid tyrosine, and «3» or «4» refers to the number of iodine atoms atttached to it.
Remember that those cute numbers after thyroid hormones — T4, the inactive form of thyroid hormone, or T3, active thyroid hormone — refer to the quantity of iodine atoms attached to thyroid hormone.
When you hear about thyroid hormones, like the T4, the T3, the T2, all of those relate back to the thyroglobulin protein a certain number of iodine atoms.
Each of the two iodine atoms is composed of a positively - charged nucleus, a number of core electrons which comprise filled electronic shells, and an unfilled (valence) shell of electrons.
The resulting strong positive charge means that the iodine atom then sucks electrons away from the methyl group, like a sort of atomic black hole.»
«The X-ray pulse initially strips the iodine atom of five or six of its electrons.
The team took a simple molecule — consisting of a benzene ring with a small nitrile arm of carbon and nitrogen and with two iodine atoms attached, one above and one below.
Zewail's team used a laser to fire a pulse of photons into a vacuum chamber filled with a heavy form of methane containing two iodine atoms.
DAMA works by recording brief flashes of light that occur inside crystals of sodium iodide when subatomic particles hit the nucleus of a sodium or iodine atom.
The researchers exchanged a single hydrogen atom by an iodine atom which modulates intermolecular interactions that resulted in more rapid insulin disassembly and release.
Replacing a hydrogen atom by an iodine atom in insulin, the hormone retains its efficacy but is available more rapidly to the organism.
Introducing the iodine atom improved the insulins» availability, while the affinity for the insulin receptor and the biological function remained unchanged when compared to the natural hormone.
These analyses showed that the iodine atoms in the carbon nanorings form extended polyiodide chains when stimulated by electricity, which gave the material electrical conductivity.
In the experiment the researchers used molecules of iodoacetylene (HCCI), which are elongated chains of four atoms — hydrogen, two carbon atoms, and an iodine atom.
Your thyroid converts tyrosine into thyroglobulin and then attaches between one and four iodine atoms to create the four forms of thyroid hormone.
The distinguishing feature of the thyroid hormones is that they contain Iodine atoms — T3 has three iodine atoms, and T4 has four.
The thyroid gland converts the amino acid tyrosine into thyroglobulin, and attaches one to four iodine atoms to create T4 (thyroxine), the inactive storage hormone, T3 (triidothyronine), or metabolically active thyroid hormone, and two thyroid hormones whose clinical significance is less known, T2 and T1.
Just as an FYI, T3 is called that because it contains 3 iodine atoms.
Your thyroid extracts this necessary ingredient from your bloodstream and uses it to make two kinds of thyroid hormone: thyroxine, also called T4 because it contains four iodine atoms, and triiodothyronine, or T3, which contains three iodine atoms.
