Enzyme Analysis: Cathepsin D as an Example

in high concentration) by direct light absorbency, or by catalytic activity. For example, the protease enzyme, savinase, which is used as an ingredient in washing powder, was determined directly by its absorbency at 200 nm (1 ). For catalytic activity

Synthesis and Properties of 7‐Substituted 7‐Deazapurine (Pyrrolo[2,3‐d]pyrimidine) 2′‐Deoxyribonucleosides

7?deazapurine (pyrrolo[2,3?d ]pyrimidine) 2??deoxyribonucleosides are synthesized by stereoselective nucleobase anion glycosylation. The introduction of a halogen at C7 is performed regioselectively either on the nucleobase or on the nucleoside. The pK a values
