  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.

    These groups share an indistinguishable part within their energy flow, providing a key position within food chains and relationships within environment(s). [2] An ecosystem is the biological organization that defines and expands on various environment factors, abiotic and biotic, that relate to simultaneous interaction. [3]

    en.wikipedia.org/wiki/Amino_acid

    Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2] Only these 22 appear in the genetic code of life. [3] [4]

    C 6-C 7-C 6 Diarylheptanoids are not included in this Harborne classification.. They can also be classified on the basis of their number of phenol groups. They can therefore be called simple phenols or monophenols, with only one phenolic group, or di-(bi-), tri-and oligophenols, with two, three or several phenolic groups respectively.

  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 ...

  9. Aldehyde - Wikipedia

    en.wikipedia.org/wiki/Aldehyde

    Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
