Human GLP-2(1-33)
Human GLP-2(1-33) is a linear 33-residue peptide with a free amino terminus and a C-terminal carboxyl group. This record describes the unmodified parent covalent structure. Orskov et al. (PMID 2714431) characterize human and pig intestinal GLP-2 as a proglucagon processing product. Horváth et al. (PMID 37528104) place GLP-2 among the gastrointestinal peptides of the glucagon family.

Identity & nomenclature
Human GLP-2(1-33) is a linear 33-residue peptide with a free amino terminus and a C-terminal carboxyl group. This record describes the unmodified parent covalent structure. Orskov et al. (PMID 2714431) characterize human and pig intestinal GLP-2 as a proglucagon processing product. Horváth et al. (PMID 37528104) place GLP-2 among the gastrointestinal peptides of the glucagon family.
“GLP-2” on its own specifies neither species nor whether a peptide is intact or shortened, so this record keeps the human (1-33) form explicit. Fragment notation does not specify a preparation’s counterion or hydration state. GSRS UNII 0825W549JC lists primary CAS 223460-79-5 for the free human 33-mer; PubChem CIDs 71300624 and 90488755 encode the same stereospecified structure, with 71300624 selected here.
Canonical name: Human glucagon-like peptide-2 (1-33).
Declared aliases and development codes: GLP-2, Glucagon-like peptide-2, Human GLP-2, hGLP-2.

Thirty-three residues numbered from His1 to Asp33. Every chiral residue is in the L configuration; Gly4 is achiral.
03
Structural characteristics
The chain runs from His1 to Asp33 with no cysteine, so it has no intramolecular disulfide bond and no covalent macrocycle.
Terminal features: Free N-terminal amino group, Free C-terminal carboxyl group.

Analytical considerations
The molecular formula and the 3766.16 Da average mass are calculated from the sequence with CIAAW 2024 abridged atomic weights. Two published average-mass values differ and remain unreconciled: 3769.136 in the PDB entity metadata for entry 2L63, and 3760.0 as the GSRS estimated calculated weight. The sequence rests on Edman, mass-spectrometric and NMR characterization of separate material sets; this is not a lot-specific certificate.

Each finding describes one cited study in its stated model. These observations are specific to that study and do not establish effects in other settings.
Cell and tissue studies
Human ileal peptide extracts in mass-spectrometry and sequencing assays
Hartmann et al. identified GLP-2 isolated from human ileal extracts as proglucagon residues 126-158 by mass spectrometry and Edman sequencing.
Reference [1]Rat ileal extracts in HPLC and radioimmunoassays
Brubaker et al. detected GLP-2-(1-33) and GLP-2-(3-33) in rat ileal extracts, with GLP-2-(3-33) accounting for 16 +/- 7% of total GLP-2 in HPLC and radioimmunoassays.
Reference [3]Human GLP-2-(1-33) with dipeptidylpeptidase IV
Brubaker et al. observed liberation of GLP-2-(3-33) when human GLP-2-(1-33) was incubated with dipeptidylpeptidase IV in an enzyme-cleavage assay.
Reference [3]Gly2-substituted human GLP-2 with dipeptidylpeptidase IV
Brubaker et al. observed that replacing Ala2 with Gly2 prevented dipeptidylpeptidase-IV cleavage of human GLP-2 in an enzyme-cleavage assay.
Reference [3]Pig and human small-intestinal extracts in radioimmunoassays
Orskov et al. detected no GLP-2-associated signal in the PG 151-160 radioimmunoassay after gel filtration of pig and human small-intestinal extracts.
Reference [4]
Animal studies
Rats in a plasma radioimmunoassay study
Brubaker et al. measured a 3.6-fold increase in total plasma immunoreactive GLP-2 in fed rats relative to fasted rats (P < 0.001) by radioimmunoassay.

Cited studies by type
The 5 papers this record cites, counted by the kind of work each reports. A count is the size of this record's selection, not of the research that exists, and says nothing about results, safety, effectiveness or approval.
A paper can report more than one kind of work. Each count opens those papers in the bibliography. Compare every record on the Evidence Map.

Methodology & citation verification
Reference identity is checked against official PubMed metadata. Local deterministic receipts bind each normalized title and canonical metadata record to its verification date. Scientific values remain absent when an authoritative source has not been verified.
