Novel physiological functions of oligosaccharides

Novel physiological functions of oligosaccharides*

This paper reviews the evidence for novel physiological functions of oligosaccharides. A history of the research and development and the types of health benefits are discussed. A key property of the physiological functions lies in the indigestibility of oligosaccharides, which gives rise to fermentation in the large intestine, followed by an increase of Bifidobacteria and short-chain fatty acid...

Novel Physiological Functions of Branched-Chain Amino Acids.

Branched-chain amino acids (BCAAs) are essential amino acids for humans and are major building blocks of proteins. Recent studies indicate that BCAAs act not only as components of proteins, but also as nutrasignals. In this review, we summarize the findings of recent studies investigating the physiological functions of BCAAs in the regulation of protein and glucose metabolism and brain function.

Glutamine’s Physiological Functions

From the perspective of nutritional science, glutamine, like arginine, is not an essential amino acid. Nevertheless, glutamine is the most abundant amino acid in the body. Glutamine plays major roles in accelerating muscle metabolism, in preserving muscle, in promoting wound healing and in cell proliferation. It also serves as the nutritional source for gastrointestinal cells and as the major e...

Genetic Evaluation of Physiological Functions

Linking physiological functions of iron.

Virtually all aerobic organisms synthesize heme, an iron protoporphyrin complex that functions as an oxygen transporter and electron carrier in multiple enzymes and mitochondrial respiratory chain complexes. Heme is synthesized by a highly conserved multistep process, beginning with the condensation of glycine and succinyl-CoA by ALA synthase (ALAS) to form 5-aminolevulinic acid, and continuing...
