The suffix “ ene ” indicates that each C atom is covalently bonded to three others ( instead of the maximum of four ), a situation that classically would correspond to the existence of bonds involving two pairs of electrons (“ double bonds ”).

When the group of covalently bound atoms bears a net charge, the group is referred to more properly as a polyatomic ion or a complex ion.

In order to associate with the inner leaflet of the plasma membrane, many G proteins and small GTPases are lipidated, that is, covalently modified with lipid extensions.

The iron is bound strongly ( covalently ) to the globular protein via the imidazole ring of the F8 histidine residue ( also known as the proximal histidine ) below the porphyrin ring.

When the planes of an ionic bond slide past one another, the resultant change in location shifts ions of the same charge into close proximity, resulting in the cleavage of the crystal ; such shift is not observed in covalently bonded crystals where fracture and crystal fragmentation occurs.

Pyrimidines are synthesized first from aspartate and carbamoyl-phosphate in the cytoplasm to the common precursor ring structure orotic acid, onto which a phosphorylated ribosyl unit is covalently linked.

Orotate is covalently linked with a phosphorylated ribosyl unit.

Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network.

* Supercoiled ( or covalently closed-circular ) DNA is fully intact with both strands uncut, and with an integral twist, resulting in a compact form.

A polyatomic ion, also known as a molecular ion, is a charged species ( ion ) composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid and base chemistry or in the formation of salts.

Quantum mechanics is also critically important for understanding how individual atoms combine covalently to form molecules.

Water is the chemical substance with chemical formula: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.

This is particularly true of metals, which often form covalently bonded molecules in the gas phase: in these cases, the enthalpy of atomization must be used to obtain a true value of the bond energy.

Rhodopsin is composed of the 11-cis-retinal covalently linked via a Schiff base to the opsin protein ( either rod opsin or blue, red or green cone opsins ).

In many cases, each of the sulfur atoms in a disulfide group is covalently bonded to a carbon atom in an organic compound, forming a disulfide bond, sometimes called a disulfide linkage or a disulfide bridge.

In most multicellular organisms, the mtDNA is organized as a circular, covalently closed, double-stranded DNA.

His-F8 of the myoglobin, also known as the proximal histidine is covalently bonded to the 5th coordination position of the iron.

And as an Oxygen binds to the 6th coordination position of the iron, a distal histidine ( a histidine that doesn't bond directly with the Iron ), His-E7 of the myoglobin binds to the Oxygen that is now covalently bonded to the iron.

The detection antibody can be covalently linked to an enzyme, or can itself be detected by a secondary antibody that is linked to an enzyme through bioconjugation.

PEGylation is the act of covalently coupling a PEG structure to another larger molecule, for example, a therapeutic protein, which is then referred to as a PEGylated protein.

For example, child welfare experience abounds with cases in which the parental request for substitute care is precipitated by a crisis event which is meaningfully linked with a fundamental unresolved problem of family relationships.

If cell Af is an information cell, it and any information cells in the Y-region that have been linked to Af each contain an address in the W-region where a potentially matching form is stored.

One who could be linked to anti-Semitism only by overcoming his objections is scarcely a good specimen of the Jew-baiter throughout the ages.

Aplu, it is suggested, comes from the Akkadian Aplu Enlil, meaning " the son of Enlil ", a title that was given to the god Nergal, who was linked to Shamash, Babylonian god of the sun.

A series of linked carbon atoms is known as the carbon skeleton or carbon backbone.

There is no limit to the number of carbon atoms that can be linked together, the only limitation being that the molecule is acyclic, is saturated, and is a hydrocarbon.

* cyclic ( general formula, n > 2 ) wherein the carbon backbone is linked so as to form a loop.

" Anxiety is also linked and perpetuated by the person's own pessimistic outcome expectancy and how they cope with feedback negativity

Economic activity is strongly linked to the United States, with which American Samoa conducts the great bulk of its foreign trade.

The history of astrometry is linked to the history of star catalogues, which gave astronomers reference points for objects in the sky so they could track their movements.

This is linked to the term to weigh anchor, meaning to lift the anchor from the sea bed, allowing the ship or boat to move.

The Greek ἀμβροσία ( ambrosia ) is semantically linked to the Sanskrit अम ृ त ( amrita ) as both words denote a drink or food that gods use to achieve immortality.

Section 39 of the Criminal Justice Act 1988 provides that common assault, like battery, is triable only in the magistrates ' court in England and Wales ( unless it is linked to a more serious offence, which is triable in the Crown Court ).

Since 2002, Actium is linked with Preveza on the north shore of the Ambracian Gulf by the Aktio-Preveza Undersea Tunnel, or Aktio-Preveza Immersed Tunnel ( traffic labels ).

A chain is a conglomeration of tiles that are linked to each other either horizontally or vertically but not diagonally.

) Thus, the sensory discrimination is linked to capacity for pleasure.

Responses such as disgust show that sensory detection is linked in instinctual ways to facial expressions, and even behaviors like the gag reflex.

This region is regarded as perhaps the one most influenced by native Indians, and its foods are closely linked to the Andean-Incan tradition.
