High-Quality Carbohydrates and Physical Performance
Numerous studies conducted over the past 40 to 50 years have consistently pointed to carbohydrate as the primary macronutrient for sustaining and improving physical performance. In recent years, however, with the advent of techniques that better allow scientists to measure the metabolism of key nutrients such as proteins/ amino acids, and studies on alternative feeding regimens such as ketogeni...
متن کاملNatural Polymer in Colon Targeting
Although oral delivery has become a widely accepted route of administration of therapeutic drugs, the gastrointestinal tract presents several formidable barriers to drug delivery. Colonic drug delivery has gained increased importance not just for the delivery of the drugs for the treatment of local diseases associated with the colon but also for its potential for the delivery of proteins and th...
متن کاملDe novo synthesis of carbohydrates and related natural products
Two synthetic strategies from achiral precutsors especially useful for sugars requiring unusual functional groups, deoxy and branched sugars, as well as partially 0protected sugars, are outlined. One strategy employs inversetype hetero-Diels-Alder reaction with highly functionalized 1-oxa-1,3-dienes. Their reaction with electron rich heterodienophiles (enol ethers, etc.) and subsequent diastere...
متن کاملNatural Fibre Reinforced Biodegradable Polymer Composites
Currently, numerous research groups have explored the production and properties of biocomposites where the polymer matrices are derived from renewable resources such as poly lactide (PLA), thermoplastic starch (TPS), cellulose and polyhydroxyalkanoates (PHAs). This review is carried out to evaluate the development and properties of natural fibre reinforced biodegradable polymer composites. They...
متن کاملSynthesis and characterization of fiber reinforced polymer scaffolds based on natural fibers and polymer for bone tissue engineering application
A wide range of materials and scaffolding fabrication methods for bone tissue engineering have beenexplored recently. Fiber reinforced polymers (FRP) system appears to be a suitable system. By the exclusiveuse of biocompatible or bio-absorbable polymers and fibers, novel generation of scaffolds for applicationsin tissue engineering can be prepared. Mulberry Silk as highlighted...
