  2. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    Functional groups binding to a central atom in a coordination complex are called ligands. Complexation and solvation are also caused by specific interactions of functional groups. In the common rule of thumb "like dissolves like", it is the shared or mutually well-interacting functional groups which give rise to solubility .

  3. Functional group (ecology) - Wikipedia

    en.wikipedia.org/wiki/Functional_group_(ecology)

    There are generally two types of functional groups that range between flora and specific animal populations. Groups that relate to vegetation science, or flora, are known as plant functional types. Also referred to as PFT for short, these often share identical photosynthetic processes and require comparable nutrients.

  4. Late-stage functionalization - Wikipedia

    en.wikipedia.org/wiki/Late-stage_functionalization

    Late-stage functionalization (LSF) is a desired, chemical or biochemical, chemoselective transformation on a complex molecule to provide at least one analog in sufficient quantity and purity for a given purpose without needing the addition of a functional group that exclusively serves to enable said transformation.

  5. Biological organisation - Wikipedia

    en.wikipedia.org/wiki/Biological_organisation

    Functional groups of cells Organ: Functional groups of tissues Organ system: Functional groups of organs Ecological levels: Organism: The basic living system, a functional grouping of the lower-level components, including at least one cell Population: Groups of organisms of the same species: Guild: Interspecific groups of organisms carrying the ...

  6. Functionality (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Functionality_(Chemistry)

    In chemistry, functionality is the presence of functional groups in a molecule. A monofunctional molecule possesses one functional group, a bifunctional (or difunctional) two, a trifunctional three, and so forth. In organic chemistry (and other fields of chemistry), a molecule's functionality has a decisive influence on its reactivity

  7. Function (biology) - Wikipedia

    en.wikipedia.org/wiki/Function_(biology)

    A functional characteristic is known in evolutionary biology as an adaptation, and the research strategy for investigating whether a character is adaptive is known as adaptationism. Although assuming that a character is functional may be helpful in research, some characteristics of organisms are non-functional, formed as accidental spandrels ...

  8. Moiety (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Moiety_(chemistry)

    It also contains an ester functional group (in red), and an acetyl functional group (encircled with dark green). Other divisions can be made. In organic chemistry, a moiety (/ ˈ m ɔɪ ə t i / MOY-ə-tee) is a part of a molecule [1] [2] that is given a name because it is identified as a part of other molecules as well.

  9. Bifunctionality - Wikipedia

    en.wikipedia.org/wiki/Bifunctionality

    In chemistry, bifunctionality or difunctionality is the presence of two functional groups in a molecule. A bifunctional species has the properties of each of the two types of functional groups, such as an alcohol (−OH), amide (−CONH 2), aldehyde (−CHO), nitrile (−CN) or carboxylic acid (−COOH). Many bifunctional species are used to ...
