Asp-Asp-Asp-Asp-Asp is a peptide consists of 5 Asp.

[Lys3]-Bombesin is a biological active peptide. (PET (Positron Emission Tomography) imaging of [Lys3]-bombesin is able to detect gastrin-releasing peptide receptor (GRPR) positive prostate cancer. An immunoconjugate of [Lys3]-bombesin and corresponding monoclonal antibody can specifically induce (CD64)-dependent monocyte and neutrophil-mediated lysis of small cell carcinoma.)

Monoethyl phthalate, a metabolite of diethyl phthalate, serves as a urinary biomarker for phthalate exposure and indicates potential risks of thyroid cancer and benign nodules.
