Glycylglycine (Gly-Gly) is a dipeptide used in biochemical research. It is the simplest of all dipeptides and is used as a starting template for preparation of more complex peptides. Glycine is involved in the body's production of DNA phospholipids and collagen and in the release of energy.

(Tyr1)-pTH (1-34) (human) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

8-Deacetylyunaconitine is a a diterpenoid alkaloid derived from Aconitum Vilmorinian Radix.
