Amide

An amide (or or), also known as an acid amide, is a compound with the functional group RnE(O)xNR′2 (R and R′ refer to H or organic groups).

Amino acid

Amino acids are organic compounds containing amine (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid.

Asparagine

Asparagine (symbol Asn or N), is an α-amino acid that is used in the biosynthesis of proteins.

Aspartic acid

Aspartic acid (symbol Asp or D; salts known as aspartates), is an α-amino acid that is used in the biosynthesis of proteins.

Beta-peptide

β-peptides consist of β amino acids, which have their amino group bonded to the β carbon rather than the α carbon as in the 20 standard biological amino acids.

Functional group

In organic chemistry, functional groups are specific substituents or moieties within molecules that are responsible for the characteristic chemical reactions of those molecules.

Isoaspartate

Isoaspartic acid (isoaspartate) is an amino acid that is an isomer of aspartic acid.

Peptide

Peptides (from Gr.: πεπτός, peptós "digested"; derived from πέσσειν, péssein "to digest") are short chains of amino acid monomers linked by peptide (amide) bonds.

Peptide bond

A peptide bond is a covalent chemical bond linking two consecutive amino acid monomers along a peptide or protein chain.

PH

In chemistry, pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution.

Post-translational modification

Post-translational modification (PTM) refers to the covalent and generally enzymatic modification of proteins following protein biosynthesis.

New!!: Deamidation and Post-translational modification · See more »

Protein

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

Pyroglutamic acid

Pyroglutamic acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) is a ubiquitous but little studied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam.

Side chain

In organic chemistry and biochemistry, a side chain is a chemical group that is attached to a core part of the molecule called "main chain" or backbone.

Steric effects

Steric effects are nonbonding interactions that influence the shape (conformation) and reactivity of ions and molecules.
