Amino Acid Derivatives

Glycine is a buffering agent that can be used in electrophoresis for protein samples. It has an optimal pH range of 2.2-3.6 and a pKa of 2.35.

Leucylarginine hinders antinociception induced by L-arginine.

Sodium lauroyl glutamate (Acylglutamate LS-11) is an amino acid detergent and increases the solubility of long-chain alkyl gallates such as alkyl gallates.

Z-Arg(Z)2-OH can be used in the assay to screen proteolytic activities in mite homogenates.

Z-Val-Ala-Asp fluoromethyl ketone (Z-VAD-fmk) is a pan-caspase inhibitor that is widely used in research studies. It is a synthetic compound that mimics the structure of natural caspase substrates and irreversibly inhibits caspase activity. Z-VAD-fmk has been shown to have anti-apoptotic properties, preventing programmed cell death in various experimental models. This compound is commonly used in studies investigating the role of caspases in cell death pathways and as a tool for evaluating the efficacy of potential therapeutic interventions. Z-VAD-fmk has also been studied for its potential as an adjuvant therapy in various diseases, including cancer and neurodegenerative disorders.

Tyrosyl-glycyl-glycine: tripeptide with L-tyrosine, two glycines, formed by enkephalinase.

Fmoc-Asp(OtBu)-Thr(psi(Me,Me)pro)-OH is a dipeptide.
