phosphate group
(Science: chemistry) A phosphate group on a larger molecule, where the phosphorus is single bonded to each of the four oxygens, and the other bond of one of the oxygens is attached to the rest of the molecule.


phosphate group
A functional group important in energy transfer.
phospholipids ...

phosphate group A chemical group composed of a central phosphorous bonded to three or four oxygens. The net charge on the group is negative. PICTURE ...

phosphate group a group derived from a molecule of phosphoric acid that connects the DNA molecules to one another.
phosphate ion a product of adenosine triphosphate (ATP) together with ADP.

Phosphate Group a phosphorus attached to four oxygens (PO4)
(phos = light; phor = bearé carry: the element phosphorus was so named because some forms "glow in the dark") ...

Phosphate Group - One of three components of a nucleotide, comprised of a central phosphorous surrounded by four oxygens.

(16) Phosphate group (inorganic phosphate, Pi) (see also phosphate group)
(a) Replace one H of phosphoric acid with carbon and you have a phosphate group (attached to that carbon)
phosphoric acid (a.k.a., inorganic phosphate or Pi): ...

phosphate groups — not water — break the 1 -> 4 linkages
the phosphate group must then be removed so that glucose can leave the cell.
The liver and skeletal muscle are major depots of glycogen.

The phosphate group is bonded to the 5 carbon of the sugar (see Figure 2), and when nucleotides are joined to form RNA or DNA, the phosphate of one nucleotide is joined to the sugar of the next nucleotide at its 3 carbon, ...

When the phosphate group detaches from the pump, the pump returns to its original shape. Its ability to bind potassium ions is decreased and its ability to bind sodium ions is increased.

There is a phosphate group which has a negative charge, there is a pentose sugar which simply means it's got five carbons.

The 5'-terminal phosphate group.
The acceptor stem is a 7-bp stem made by the base pairing of the 5'-terminal nucleotide with the 3'-terminal nucleotide (which contains the CCA 3'-terminal group used to attach the amino acid).

One molecule of ATP has three phosphate groups that are bound together. When a bond between phosphates is broken, energy is released. This energy can be used to power another chemical reaction.

A building block of DNA and RNA, consisting of a nitrogenous base, a five-carbon sugar, and a phosphate group. Together, the nucleotides form codons, which when strung together form genes, which in turn link to form chromosomes.

The free 3' C normally carries a - OH group, and the 5' C a phosphate group.
Annealing Formation of double-stranded molecules from two single strands of nucleic acid by base pairing of complementary sequence.

The nucleotides have 3 phosphate groups and are called deoxyribonucleoside triphosphates. Two of these phosphate groups break off during the replication process to release energy.

Most of the lipids in the bilayer can be more precisely described as phospholipids, that is, lipids that feature a phosphate group at one end of each molecule.

These nucleotides are composed of a nitrogenous base (A = adenine, T = thymine, C = cytosine, G = guanine) attached to a sugar called deoxyribose and the sugar is attached to a phosphate group which is negatively charged.

Steps in the signal transduction pathway often involve the addition or removal of phosphate groups which results in the activation of proteins. Enzymes that transfer phosphate groups from ATP to a protein are called protein kinases.

If you remove just one of these phosphate groups from the end, so that there are just two phosphate groups, the molecule is much happier. This conversion from ATP to ADP is an extremely crucial reaction for the supplying of energy for life processes.

A nucleotide is made up of a nitrogenous base and a phosphate group covalently bonded to a five-carbon sugar molecule (deoxyribose in DNA and ribose in RNA). purines and pyrimidines.

The ATP synthetase (or ATP synthase) of mitochondria and chloroplasts is an anabolic enzyme that harnesses the energy of a transmembrane proton gradient as an energy source for adding an inorganic phosphate group to a molecule of adenosine ...

Kinase: A kinase is in general an enzyme that catalyzes the transfer of a phosphate group from ATP to something else. In molecular biology, it has acquired the more specific verbal usage for the transfer onto DNA of a radiolabeled phosphate group.

Atoms in the sugar component of a nucleotide provide the link between the base and the phosphate group. The 1' carbon is attached to the 9 nitrogen of a purine, or the 1 nitrogen of a pyrimidine.

Proteins may be modified in a wide variety of ways, including phosphorylation (addition or a phosphate group), adenylation (addition of an adenine group), glycosylation (addition of a sugar group), acylation (addition of a lipid group), ...

An enzyme that transfers the terminal (γ) phosphate group from ATP to a substrate.

An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), uracil (U), cytosine (C), or guanine (G).

- An enzyme that removes 5'-phosphate groups from the ends of DNA molecules, leaving 5'-hydoxyl groups
Allele
- One of two or more alternative forms of a gene which are usually recognizable by phenotypes ...

And so the addition of this chemical group, this phosphate group, to the protein actually makes a negative charge, and that can affect the structure, and also actually regulate the activity or function of that protein.

Phosphodiester bond. A bond in which a phosphate group joins adjacent carbons through ester linkages. A condensation reaction between adjacent nucleotides results in a phosphodiester bond between 3' and 5' carbons in DNA and RNA.

phosphorylation The addition of a phosphate group to a molecule.
photic zone The surface layer where there is enough light for photosynthesis to occur. Also see epipelagic zone.

Kinase catalyzes the transfer of a phosphate group from ATP to DNA, protein or other substrates.
