anti-hepatocyte antibody
24 October 2022Anti-Hepatocyte Specific Antigen antibody
Diagnostic use
Hepatocyte specific antigens are useful in studying hepatocellular tumors.
They may be useful in differentiating clear cell hepatocellular carcinomas from other clear cell malignancies.
They have been shown in the literature to be useful in differentiating hepatoblastoma of embryonal type from small round cell tumors of childhood.
Hepatcoyte labels an antigen in the mitochondrial fraction of the liver homogenates.

energy
20 April 2022WKP
Definition : Energy is a physical quantity measuring the capacity of a system to modify a state, to produce a work producing a movement, heat or an electromagnetic radiation.
In physics, energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
Energy is a conserved quantity. The law of conservation of energy states that energy can be converted in form, but not created or (...) -
Precambrian
3 April 2022precambrian WKP
Definition : The Precambrian ( Cryptozoic ) is the earliest part of Earth history, set before the current Phanerozoic Eon.
The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied.
The Precambrian accounts for 88% of the Earth’s geologic (...) -
organic chemistry
3 April 2022WKP
Definition : Organic chemistry is a branch of chemistry that studies the structure, properties and reactions of organic compounds, which contain carbon-carbon covalent bonds. Study of structure determines their structural formula.
The study of organic reactions includes the chemical synthesis of natural products , drugs , and polymers , and study of individual organic molecules in the laboratory and via theoretical (in silico) (...) -
organic transformation
3 April 2022The IUPAC nomenclature for organic transformations
The IUPAC Nomenclature for Transformations is a methodology for naming a chemical reaction. Traditionally a chemical reaction especially in organic chemistry is named after its inventor, the so-called name reaction.

chemical reaction
3 April 2022WKP
Definition : A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.
Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.
Nuclear chemistry is a sub-discipline of chemistry that involves the chemical (...) -
catalysis
3 April 2022WKP
Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst.
Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate.
Catalysts generally react with one or more reactants to form intermediates that subsequently give the final (...) -
