THE Schlack and Kumpf procedure 1 for identifying the amino-acids which provide terminal carboxyl groups in peptides has been made the basis of a micro method which works well with simple peptides ...

Thus, when a reagent reacts specifically with a particular group to produce a derivative which has significantly different electrophilic characteristics, a corresponding change in the spectrum is ...

They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino acids are characterized by their central carbon atom, known as the α-carbon, which is bonded ...
