  2. Condensation reaction - Wikipedia

    en.wikipedia.org/wiki/Condensation_reaction

    The reaction may otherwise involve the functional groups of the molecule, and is a versatile class of reactions that can occur in acidic or basic conditions or in the presence of a catalyst. This class of reactions is a vital part of life as it is essential to the formation of peptide bonds between amino acids and to the biosynthesis of fatty ...

  3. Peptide bond - Wikipedia

    en.wikipedia.org/wiki/Peptide_bond

    Peptide bond formation via dehydration reaction. When two amino acids form a dipeptide through a peptide bond, [1] it is a type of condensation reaction. [2] In this kind of condensation, two amino acids approach each other, with the non-side chain (C1) carboxylic acid moiety of one coming near the non-side chain (N2) amino moiety of the other.

  4. Peptide synthesis - Wikipedia

    en.wikipedia.org/wiki/Peptide_synthesis

    In organic chemistry, peptide synthesis is the production of peptides, compounds where multiple amino acids are linked via amide bonds, also known as peptide bonds. Peptides are chemically synthesized by the condensation reaction of the carboxyl group of one amino acid to the amino group of another.

  5. Amino acid - Wikipedia

    en.wikipedia.org/wiki/Amino_acid

    The condensation of two amino acids to form a dipeptide. The two amino acid residues are linked through a peptide bond. As both the amine and carboxylic acid groups of amino acids can react to form amide bonds, one amino acid molecule can react with another and become joined through an amide linkage.

  6. Strecker amino acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Strecker_amino_acid_synthesis

    The Strecker amino acid synthesis, also known simply as the Strecker synthesis, is a method for the synthesis of amino acids by the reaction of an aldehyde with cyanide in the presence of ammonia. The condensation reaction yields an α-aminonitrile, which is subsequently hydrolyzed to give the desired amino acid.

  7. Condensation polymer - Wikipedia

    en.wikipedia.org/wiki/Condensation_polymer

    One important class of condensation polymers are polyamides. [4] They arise from the reaction of carboxylic acid and an amine. Examples include nylons and proteins. When prepared from amino-carboxylic acids, e.g. amino acids, the stoichiometry of the polymerization includes co-formation of water: n H 2 N-X-CO 2 H → [HN-X-C(O)] n + (n-1) H 2 O

  8. Biomolecular condensate - Wikipedia

    en.wikipedia.org/wiki/Biomolecular_condensate

    Since biomolecular condensation generally involves oligomeric or polymeric interactions between an indefinite number of components, it is generally considered distinct from formation of smaller stoichiometric protein complexes with defined numbers of subunits, such as viral capsids or the proteasome – although both are examples of spontaneous ...

  9. Protein structure - Wikipedia

    en.wikipedia.org/wiki/Protein_structure

    A single amino acid monomer may also be called a residue, which indicates a repeating unit of a polymer. Proteins form by amino acids undergoing condensation reactions, in which the amino acids lose one water molecule per reaction in order to attach to one another with a peptide bond.
