An intermediate is a molecular entity produced from a reactant during a chemical reaction, and then reacts further to give the final product. It is also called a reaction intermediate.Most chemical reactions are multi-step processes where several simple reactions occur in sequence , and the product of each steps being an intermediate.
Polymer compounds are substances with large molecular weights. Depending on their origin, they are classified as natural polymers or synthetic polymers. Common examples include starch, proteins, and PET.
A methane molecule is formed by the covalent bonding of one carbon atom with four hydrogen atoms, represented by the molecular formula CH₄. It is a simple hydrocarbon that exists as a gas at room temperature. Methane is the primary component of natural gas, making it a widely used and valuable energy source.
A fluorine molecule is formed by the covalent bonding of two fluorine atoms, represented by the molecular formula F₂. Although it exists as a diatomic molecule, it does not occur naturally in its elemental form due to its high reactivity. It is a highly toxic gas with strong oxidizing properties. It is effective in treating the surface of teeth, which is why fluoride compounds are commonly included in toothpaste and widely used.
Molecular hydrogen is a molecule formed by the covalent bonding of two hydrogen atoms. It is a single molecule represented by the molecular formula H2 and exists as a gas at room emperature. In recent years, depending on the combustion conditions, hydrogen is expected to become an alternative energy source because it does not emit greenhouse gases when combusted and has a low environmental impact.
A covalent bond is a type of chemical bond in which atoms give up their own electrons and bond together by sharing electrons. The bonds are strong and most molecules are formed through covalent bonds.
ATP is adenosine triphosphate. It is involved in the storage and utilization of energy for vital activities, such as muscle contraction.
Biochemical reactions are chemical precesses that sustain the life of living cells and support cell proliferation.
Mexameter is an instrument used to measure melanin and erythema, both of which are important elements in forming skin color.
Molecular markers are biomolecules found in body tissues such as blood and body fluids that serve as objective indicators of the presence or absence of disease, changes in disease status, and the effectiveness of treatment. They are a type of biomarker, also known as molecular biomarkers.
