Deoxyadenosine monophosphate (dAMP), also known as deoxyadenylic acid or deoxyadenylate in its conjugate acid and conjugate base forms, respectively, is a derivative of the common nucleotide AMP, or adenosine monophosphate, in which the -OH group on the 2' carbon on the nucleotide's pentose has been reduced to just a hydrogen atom (hence the "deoxy-" part of the name).
Compared to B-DNA, the A-DNA form is a wider right-handed spiral, with a shallow, wide minor groove and a narrower, deeper major groove. The A form occurs under non-physiological conditions in partly dehydrated samples of DNA, while in the cell it may be produced in hybrid pairings of DNA and RNA strands, and in enzyme-DNA complexes.
As a substituent it takes the form of the prefix adenylyl-. [2] AMP plays an important role in many cellular metabolic processes, being interconverted to adenosine triphosphate (ATP) and adenosine diphosphate (ADP), as well as allosterically activating enzymes such as myophosphorylase-b. AMP is also a component in the synthesis of RNA. [3]
In chemistry, absolute configuration refers to the spatial arrangement of atoms within a molecular entity (or group) that is chiral, and its resultant stereochemical description. [1] Absolute configuration is typically relevant in organic molecules where carbon is bonded to four different substituents .
1,5-Diazabicyclo[4.3.0]non-5-ene (DBN) is a chemical compound with the formula C 7 H 12 N 2. [1] It is an amidine base used in organic synthesis. A related compound with related functions is 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The relatively complex nature of the formal names for DBU and DBN (hence the common use of acronyms) reflects the ...
A do-not-resuscitate order (DNR), also known as Do Not Attempt Resuscitation (DNAR), Do Not Attempt Cardiopulmonary Resuscitation (DNACPR [3]), no code [4] [5] or allow natural death, is a medical order, written or oral depending on the jurisdiction, indicating that a person should not receive cardiopulmonary resuscitation (CPR) if that person's heart stops beating. [5]
DEAD was used in the original 1967 article by Oyo Mitsunobu, [14] and his 1981 review on the use of diethyl azodicarboxylate is a top-cited chemistry article. [ 15 ] [ 16 ] The Mitsunobu reaction has several applications in the synthesis of natural products and pharmaceuticals.
The Z-DNA structure. Proteopedia Z-DNA. Z-DNA is one of the many possible double helical structures of DNA.It is a left-handed double helical structure in which the helix winds to the left in a zigzag pattern, instead of to the right, like the more common B-DNA form.
