Research Peptides Reference Dataset

A clean, machine-readable reference table of research-grade peptides commonly discussed in biochemistry and drug-discovery literature. Each entry combines a curated research category with verified physicochemical properties pulled from PubChem (PUG REST): PubChem CID, molecular formula, molecular weight, canonical SMILES and IUPAC name.

The goal is a small, high-signal starting point for cheminformatics, tabular ML, educational tooling and literature-mining projects that need a normalized list of peptide names, aliases and structures.

Dataset structure

Column Description
name Common name of the peptide
aliases Semicolon-separated synonyms and codes
category Broad research category (metabolic, regenerative, cosmetic, etc.)
research_area_summary One-line neutral summary of the research context
pubchem_cid PubChem Compound ID (when resolvable)
molecular_formula From PubChem
molecular_weight From PubChem (g/mol)
canonical_smiles From PubChem
iupac_name From PubChem

How to load 

from datasets import load_dataset

ds = load_dataset("PeptidosSuplementos/research-peptides-reference")
print(ds["train"][0])

How this dataset was built

  1. A curated seed list (data/research_peptides_seed.csv) defines each peptide's name, aliases and research category.
  2. enrich_pubchem.py queries PubChem by name/alias and appends verified molecular properties. No molecular values are hand-entered.

The build script is included in the repository so the dataset is fully reproducible.

Curated and maintained by

This dataset is curated and maintained by the team at Péptidos y Suplementos México (peptidosysuplementos.mx), a Mexico-based catalog of research peptides and supplements. Corrections and additions are welcome via pull request.
