Maltotriose is a common oligosaccharide metabolite found in human urine after maltose ingestion or infusion. Maltotriose is increased in Glycogen storage disease II due to a mutation of the enzyme alpha-14-glucosidase.

Carassin is a 21 amino acid tachykinin-related peptide, it can be isolated from the goldfish brain. Carassin has moderate affinity for rat tachykinin binding sites.

(Nle8,18,Tyr34)-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.
