Collagens—structure, function, and biosynthesis

compactifications and function spaces on weighted semigruops

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...

Collagens--structure, function, and biosynthesis.

The extracellular matrix represents a complex alloy of variable members of diverse protein families defining structural integrity and various physiological functions. The most abundant family is the collagens with more than 20 different collagen types identified so far. Collagens are centrally involved in the formation of fibrillar and microfibrillar networks of the extracellular matrix, baseme...

Biosynthesis and function of secondary metabolites

Natural products have long been used by humans owing to their beneficial effects. Indulgences such as coffee and tea, with their moderate stimulatory properties, have a long cultural tradition and are today some of the most important agricultural products worldwide. Other drugs have much stronger impacts on the central nervous system. For example, coca was originally used by the Inca civilisati...

Biosynthesis and biological function of sulfoglycolipids

Sulfation confers negative charge on glycolipids and the attached sulfate group presents a part of determinants for the molecular interactions. Mammalian sulfoglycolipids are comprised of two major members, sulfatide (SO3-3Gal-ceramide) and seminolipid (SO3-3Gal-alkylacylglycerol). Sulfatide is abundant in the myelin sheath and seminolipid is unique to the spermatogenic cells. The carbohydrate ...
