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 phosphorus attached to four oxygens (PO4)
(phos = light; phor = bear‚ carry: the element phosphorus was so named because some forms "glow in the dark") ...
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.
When the phosphate group detaches from the pump, the pump returns to its original shape. The two potassium ions leave and three sodium ions enter. The cycle then repeats itself.

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).

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.
Every strand of the DNA is a huge natural polymer of repeating nucleotide units, each of which comprises a phosphate group, a sugar (deoxyribose), and a base (either adenine, thymine, cytosine, or guanine).
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.
Identifying the location of phosphate groups.
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 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.
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 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).
(Adenosine TriPhosphate) A molecule consisting of adenosine (adenine plus a ribose sugar) and three phosphate groups.
- 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.
