  2. Pentaethylenehexamine - Wikipedia

    en.wikipedia.org/wiki/Pentaethylenehexamine

    Pentaethylenehexamine is a hexadentate ligand, owing to the Lewis basicity of the six amine groups. [3] Pentaethylenehexamine is in the category of polyethyleneamines and is part of mixtures of these sold commercially. [2] Commercial supplies of pentaethylenehexamine contain, in addition to the linear form, branched and cyclic polyamines. [2]

  3. Tetraethylenepentamine - Wikipedia

    en.wikipedia.org/wiki/Tetraethylenepentamine

    Tetraethylenepentamine (TEPA) is an organic compound and is in the class of chemicals known as ethyleneamines. It is a slightly viscous liquid and is not colorless but, like many amines, has a yellow color.

  4. Polyethylenimine - Wikipedia

    en.wikipedia.org/wiki/Polyethylenimine

    Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups.

  5. Sterol - Wikipedia

    en.wikipedia.org/wiki/Sterol

    Sterols and related compounds play essential roles in the physiology of eukaryotic organisms, and are essential for normal physiology of plants, animals, and fungi. [4] For example, cholesterol forms part of the cellular membrane in animals, where it affects the cell membrane's fluidity and serves as secondary messenger in developmental signaling.

  6. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3.It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium).

  7. Molecular probe - Wikipedia

    en.wikipedia.org/wiki/Molecular_probe

    A molecular probe is a group of atoms or molecules used in molecular biology or chemistry to study the properties of other molecules or structures. If some measurable property of the molecular probe used changes when it interacts with the analyte (such as a change in absorbance), the interactions between the probe and the analyte can be studied ...

  8. Biomolecular condensate - Wikipedia

    en.wikipedia.org/wiki/Biomolecular_condensate

    A number of experimental and computational methods have been developed to examine the physico-chemical properties and underlying molecular interactions of biomolecular condensates. Experimental approaches include phase separation assays using bright-field imaging or fluorescence microscopy , and fluorescence recovery after photobleaching (FRAP ...

  9. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
