The phthaloyl group (phthaloyl, Phth) is a classical protecting unit for primary amines, but in modern routine peptide synthesis it is not among the most commonly used backbone amino-protecting systems. Current protecting-group design places greater emphasis on orthogonal deprotection, ...
Specific rotation measurement remains part of pharmacopeial practice, quality control, and chiral sample characterization because it is still efficient and practical for identity confirmation, batch-to-batch comparison, and rapid screening. What truly deserves attention is its high sensitivity ...
The GPX family constitutes an important enzymatic system in the regulation of cellular redox homeostasis and participates in peroxide clearance, termination of lipid peroxidation, maintenance of membrane homeostasis, and control of stress-induced injury. Different members exhibit clear ...
MAT catalyzes the conversion of methionine and ATP into S-adenosylmethionine (SAM). SAM is not only one of the most central active methyl donors in cells, but also lies at the intersection of one-carbon metabolism, epigenetic regulation, and stress adaptation. As mechanisms involving MAT1A/MAT2A ...
The extracellular matrix is not a static scaffold simply composed of collagen, elastin, and several adhesion molecules. Its functional state largely depends on the spatial structure, ligand-binding capacity, and local signal distribution shaped by glycosylation. Glycosaminoglycan chains, glycan ...
The coagulation-anticoagulation protein network is the fundamental system that maintains blood fluidity, localized hemostasis, and vascular integrity. This network is not a simple linear chain composed of several independent coagulation factors, but rather a multi-node coupled structure formed ...
Neuropeptides constitute the central integrative layer of energy homeostasis regulation. The hypothalamus–brainstem network continuously receives signals from the gastrointestinal tract, adipose tissue, pancreas, liver, and circulating nutrient substrates, and in turn reshapes feeding, ...
Plasma proteins do not merely maintain colloid osmotic pressure or serve as passive carriers, but instead constitute a core functional layer in the circulatory system for metal coordination, inflammatory reprogramming, and injury buffering. Transferrin, ceruloplasmin, albumin, haptoglobin, and ...
The skin is chronically exposed to multiple oxidative environments, including ultraviolet radiation, air pollution, ozone, visible light, and endogenous metabolic stress. The key to maintaining cutaneous homeostasis does not lie in a single antioxidant ingredient, but in a continuous defense ...
