The peptide knowledge base

This peptide knowledge base is built in four layers rather than as an alphabetical list. The fundamentals sit first because every other page quietly assumes them; then the metabolic pages, where the published evidence runs deepest; then one file per molecule; then the practical material about work at the bench. Reading downwards through those layers is faster than searching, if the subject is new to you.

Each compound file follows the same four headings, so any two of them can be set side by side without reading either in full. Every file also states how mature its field is, and that varies far more than the uniform layout suggests. If you would rather approach the same material by research question than by molecule, the research areas index groups the compounds by the literature they belong to, and the weight research area is the busiest of the eight.

What these pages leave out is as deliberate as what they contain. None of them carries dosing, protocols or outcome claims, and nothing written here should be taken on our word alone. The handling questions that come up most often, how quickly material degrades, what storage does to it, have a published literature of their own, indexed on PubMed under peptide stability. The same goes for the warning signs we describe: the list of supplier red flags applies to this shop exactly as it applies to any other.

Fundamentals

Three pages that everything else on this site quietly assumes you have read.

Metabolic research

The busiest corner of the field, and the one with the widest gap between what is published and what gets claimed online.

Compound files

One file per molecule, all built to the same four headings: where it came from, how it is built, what has been measured, and what is not being claimed.

At the bench

Handling, storage and the practical decisions that determine whether a series stays reproducible.
