Nicotinamide adenine dinucleotide represents an important coenzyme in the context of energy metabolism. It is derived from niacin (vitamin B3, nicotinic acid amide). Deficiency of vitamin B3 results in the symptoms of pellagra. What is nicotinamide adenine dinucleotide? Nicotinamide adenine dinucleotide is a coenzyme that transfers a hydride ion (H-) as part of energy metabolism. … Nicotinamide Adenine Dinucleotide: Function & Diseases
Archaea, or primordial bacteria, are cellular life forms in addition to the other groups of bacteria and eukaryotes. In the late 1970s, the archaea were described and classified as a distinct group by microbiologists Carl Woese and George Fox. What are archaea? Archaea are single-celled organisms that possess DNA (deoxyribonucleic acid) in the form of … Archaea: Infection, Transmission & Diseases
A base pair consists of two nucleobases that face each other in deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), bind to each other, and form the double strand with the help of hydrogen brϋcken. This is the genomic information of an organism and includes the genes. Incorrect base pairing can lead to mutations. What is … Base Pairing: Function, Tasks, Role & Diseases
Adenosine triphosphate or ATP is the most energy-rich molecule in the organism and is responsible for all energy-transferring processes. It is a mononucleotide of the purine base adenine and therefore also represents a building block of nucleic acids. Disturbances in the synthesis of ATP inhibit the release of energy and lead to states of exhaustion. … Adenosine Triphosphate: Function & Diseases
Adenosine diphosphate (ADP) is a mononucleotide containing the purine base adenine and plays a central role in all metabolic processes. Together with adenosine triphosphate (ATP), it is responsible for energy turnover in the organism. Most disorders in the function of ADP are mitochondrial in origin. What is adenosine diphosphate? Adenosine diphosphate, as a mononucleotide, consists … Adenosine Diphosphate: Function & Diseases
Adenosine monophosphate is a nucleotide that can be part of the energy carrier adenosine triphosphate (ATP). As a cyclic adenosine monophosphate, it also performs the function of a second messenger. Among other things, it is formed during the cleavage of ATP, which releases energy. What is adenosine monophosphate? Adenosine monophosphate (C10H14N5O7P) is a nucleotide and … Adenosine Monophosphate: Function & Diseases
Purine is an organic compound and a heteroaromatic with four nitrogen atoms, becomes the finished purine nucleus by five additional carbon atoms and forms the basic body of the entire substance group of purines. The latter are important building blocks of nucleic acids and at the same time the stores of hereditary information. Purines are … Purine: Function & Diseases
With the help of purine synthesis, all living organisms produce purines. Purine is, among other things, a component of the DNA bases guanine and adenine as well as of the important energy carrier ATP. What is purine synthesis? With the help of purine synthesis, all living things make purines. Purine is, among other things, a … Purine Synthesis: Function, Role & Diseases
Poducts Mercaptopurine is commercially available in tablet and oral suspension form (Puri-Nethol, Xaluprine). The active ingredient has been approved in many countries since 1955. Structure and properties Mercaptopurine (C5H4N4S – H2O, Mr = 170.2 g/mol) exists as a yellow crystalline powder that is practically insoluble in water. It is an analog of the purine bases … Mercaptopurine
Cytosine is a nucleic base that is a building block of DNA and RNA. It and three other nucleic bases make up the genetic code of every living thing. What is cytosine? The exact chemical name of cytosine is 4-amino-1H-pyrimidin-2-one because the amino group of the nucleic base is located at the fourth standard position … Cytosine: Function & Diseases
Methylation is a chemical process in which a methyl group is transferred from one molecule to another. In DNA methylation, a methyl group couples to a specific part of DNA, thus altering a building block of the genetic material. What is DNA methylation? In DNA methylation, a methyl group couples to a specific part of … DNA Methylation: Function, Role & Diseases
DNA synthesis occurs as part of the replication of DNA. DNA is the carrier of genetic information and controls all life processes. It is located in the nucleus of the cell in humans as in all other living organisms. DNA has the form of a double strand, similar to a winding rope ladder, which is … DNA Synthesis: Function, Tasks, Role & Diseases
