  2. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group (−CH 3) that is single-bonded to a carbonyl (C=O), making it an acyl group. The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R) of the molecule.

  3. Acetal - Wikipedia

    en.wikipedia.org/wiki/Acetal

    This tendency reflects the fact that low molecular weight aldehydes are prone to self-condensation such that the C=O bond is replaced by an acetal. The acetal formed from formaldehyde (two hydrogens attached to the central carbon) is sometimes called a formal [4] or the methylenedioxy group. The acetal formed from acetone is sometimes called an ...

  4. T-groups - Wikipedia

    en.wikipedia.org/wiki/T-groups

    A T-group or training group (sometimes also referred to as sensitivity-training group, human relations training group or encounter group) is a form of group training where participants (typically between eight and fifteen people) learn about themselves (and about small group processes in general) through their interaction with each other.

  6. Cognitive categorization - Wikipedia

    en.wikipedia.org/wiki/Cognitive_categorization

    Categorization is a type of cognition involving conceptual differentiation between characteristics of conscious experience, such as objects, events, or ideas.It involves the abstraction and differentiation of aspects of experience by sorting and distinguishing between groupings, through classification or typification [1] [2] on the basis of traits, features, similarities or other criteria that ...

  7. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds.

  8. Protecting group - Wikipedia

    en.wikipedia.org/wiki/Protecting_group

    The acetal is then called a protecting group for the carbonyl. After the hydride step is complete, aqueous acid removes the acetal, restoring the carbonyl. After the hydride step is complete, aqueous acid removes the acetal, restoring the carbonyl.

  9. Acetyl-CoA - Wikipedia

    en.wikipedia.org/wiki/Acetyl-CoA

    The acetyl group (indicated in blue in the structural diagram on the right) of acetyl-CoA is linked to the sulfhydryl substituent of the β-mercaptoethylamine group. This thioester linkage is a "high energy" bond, which is particularly reactive.
