  2. Phosgene - Wikipedia

    en.wikipedia.org/wiki/Phosgene

    The reaction of an organic substrate with phosgene is called phosgenation. [9] Phosgenation of diols give carbonates (R = H, alkyl, aryl), which can be either linear or cyclic: n HO−CR 2 −X−CR 2 −OH + n COCl 2 → [−O−CR 2 −X−CR 2 −O−C(=O)−] n + 2n HCl. An example is the reaction of phosgene with bisphenol A to form ...

  3. P-bodies - Wikipedia

    en.wikipedia.org/wiki/P-bodies

    In cellular biology, P-bodies, or processing bodies, are distinct foci formed by phase separation within the cytoplasm of a eukaryotic cell consisting of many enzymes involved in mRNA turnover. [1] P-bodies are highly conserved structures and have been observed in somatic cells originating from vertebrates and invertebrates , plants and yeast .

  4. Biological process - Wikipedia

    en.wikipedia.org/wiki/Biological_process

    Response to stimuli: a response can take many forms, from the contraction of a unicellular organism to external chemicals, to complex reactions involving all the senses of multicellular organisms. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (phototropism), and chemotaxis.

  5. Biochemical cascade - Wikipedia

    en.wikipedia.org/wiki/Biochemical_cascade

    The basic unit of the Reactome database is a reaction; reactions are then grouped into causal chains to form pathways [115] The Reactome data model allows us to represent many diverse processes in the human system, including the pathways of intermediary metabolism, regulatory pathways, and signal transduction, and high-level processes, such as ...

  6. Metabolism - Wikipedia

    en.wikipedia.org/wiki/Metabolism

    Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...

  7. Pentose phosphate pathway - Wikipedia

    en.wikipedia.org/wiki/Pentose_phosphate_pathway

    The reactions of this pathway are mostly enzyme catalyzed in modern cells, however, they also occur non-enzymatically under conditions that replicate those of the Archean ocean, and are catalyzed by metal ions, particularly ferrous ions (Fe(II)). [5] This suggests that the origins of the pathway could date back to the prebiotic world.

    Traces of a toxic, colorless gas were found at the headquarters of Sweden’s security agency where a suspected gas leak last week forced authorities to evacuate some 500 people from the facility ...

  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 ...
