Molecule

Wang and Landers’ work with boron-dipyrromethene (BODIPY), an organic compound that acts as a photosensitizer – a molecule that brings about a chemical change in another molecule (decontamination of the HD molecule in this case) in the presence of light.

A molecule of lactose is formed by the combination of a molecule of galactose with a molecule of glucose.

A molecule of sucrose is formed by the combination of a molecule of glucose with a molecule of fructose.

Humid air is less dense than dry air because a molecule of water ( ≈ 18 ) is less massive than either a molecule of nitrogen (M ≈ 28) or a molecule of oxygen (M ≈ 32).

This phenomenon, where molecule Y affects the binding of molecule X to a transport molecule Z, is called a heterotropic allosteric effect.

Firstly, the molecule should form stable hybrids when paired with the corresponding RNA molecule—a process that requires both thermostability and stability over time.

When these ionized particles impact Europa, they break up the water-ice molecule by molecule on the surface to produce hydrogen and oxygen.

Such a molecule will take its radiation tag to the heart and you can visualise the heart structure with all its chambers and vessels using the X-ray-like image that is generated by the radiation emission from the radionuclide on the molecule.

A compound that has two immiscible hydrophilic and hydrophobic parts within the same molecule is called an amphiphilic molecule.

A molecule with a permanent dipole moment is called a polar molecule.

A myristyric acid molecule is attached to this analogue, which in turn associates the insulin molecule to the abundant serum albumin, which in turn extends the effect and reduces the risk of hypoglycemia.

An example of a dipole-dipole interaction can be seen in hydrogen chloride (HCl): the positive end of a polar molecule will attract the negative end of the other molecule and influence its position.

As building the larger sugar ejects a water molecule, breaking it down consumes a water molecule.

Because of its asymmetry, the carbon monoxide molecule produces far brighter spectral lines than the hydrogen molecule, making CO much easier to detect.

Because two acetyl-CoA molecules are produced from each glucose molecule, two cycles are required per glucose molecule.

Flint is often deposited around larger fossils such as Echinoidea which may be silicified (i.e. replaced molecule by molecule by flint).

If a crystal or molecule consists of atoms of more than one kind, the distribution of charges around an atom in the crystal or molecule leans to positive or negative.

If an explosive molecule contains just enough oxygen to convert all of its carbon to carbon dioxide, all of its hydrogen to water, and all of its metal to metal oxide with no excess, the molecule is said to have a zero oxygen balance.

If we look at the relative masses of oxygen and hydrogen in a water molecule, we see that 94% of the mass of a water molecule is accounted for by oxygen and the remaining 6% is the mass of hydrogen.

In 1976, Sänger et al. citation presented evidence that potato spindle tuber viroid is a "single-stranded, covalently closed, circular RNA molecule, existing as a highly base-paired rod-like structure"—believed to be the first such molecule described.
