  2. 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.

  3. Peptide - Wikipedia

    en.wikipedia.org/wiki/Peptide

    A neuropeptide is a peptide that is active in association with neural tissue. A lipopeptide is a peptide that has a lipid connected to it, and pepducins are lipopeptides that interact with GPCRs. A peptide hormone is a peptide that acts as a hormone. A proteose is a mixture of peptides produced by the hydrolysis of proteins. The term is ...

  4. Protein primary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_primary_structure

    In this modification, an asparagine or aspartate side chain attacks the following peptide bond, forming a symmetrical succinimide intermediate. Hydrolysis of the intermediate produces either aspartate or the β-amino acid, iso(Asp). For asparagine, either product results in the loss of the amide group, hence "deamidation". hydroxylation

  5. 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.

  6. Chemical specificity - Wikipedia

    en.wikipedia.org/wiki/Chemical_specificity

    A reaction that illustrates an enzyme cleaving a specific bond of the reactant in order to create two products Bond specificity, unlike group specificity, recognizes particular chemical bond types. This differs from group specificity, as it is not reliant on the presence of particular functional groups in order to catalyze a particular reaction ...

  7. Carboxypeptidase - Wikipedia

    en.wikipedia.org/wiki/Carboxypeptidase

    A carboxypeptidase (EC number 3.4.16 - 3.4.18) is a protease enzyme that hydrolyzes (cleaves) a peptide bond at the carboxy-terminal (C-terminal) end of a protein or peptide. This is in contrast to an aminopeptidases, which cleave peptide bonds at the N-terminus of proteins. Humans, animals, bacteria and plants contain several types of ...

  8. Protein tertiary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_tertiary_structure

    Amino acid side chains and the backbone may interact and bond in a number of ways. The interactions and bonds of side chains within a particular protein determine its tertiary structure. The protein tertiary structure is defined by its atomic coordinates. These coordinates may refer either to a protein domain or to the entire tertiary structure.

  9. Corey-Pauling rules - Wikipedia

    en.wikipedia.org/wiki/Corey-Pauling_rules

    In biochemistry, the Corey-Pauling rules are a set of three basic statements that govern the secondary nature of proteins, in particular, the CO-NH peptide link. They were originally proposed by Robert Corey and Linus Pauling. [1] The rules are as follows: The atoms in a peptide link all lie on the same plane.
