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.



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 ...

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") ...

- 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): ...

s — not water — break the 1 -> 4 linkages
the 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, ...

The carries a negative charge.
Additional smaller groups may be attached to the to form a variety of phospholipids.
The interaction of phospholipids with water is complex.

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

Contains three phosphate groups connected to each other in sequence

The 5'-terminal .
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 .
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 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 s which results in the activation of proteins. Enzymes that transfer s from ATP to a protein are called protein kinases.

They bind to the phosphate groups of DNA by their amino termini. There are five major types of histone proteins.

If you remove just one of these s from the end, so that there are just two s, 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.

Identifying the location of s.
Is DNA a right- or left-handed helix?
Grooves in the DNA double helix.
The deoxyribose sugar ring.
Is the deoxyribose ring flat or puckered?
Location of the sugar in the DNA double helix.

He found it contained four nitrogenous bases: cytosine, thymine, adenine, and guanine; deoxyribose sugar; and a phosphate group.

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 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 . 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) from ATP to a substrate.

Adenosine (ribose + adenine) triphosphate (3 phosphate groups)
Produced by adding Pi to ADPphosphorylation
Breaks down to ADP (adenosine diphosphate) and Pi (inorganic phosphate ion) by hydrolysis ...

An RNA strand has a backbone made of alternating sugar (ribose) and s. 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 , 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 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.
