Exempel på hur man kan använda POLYOL i en mening

• Their target, aldose reductase, is an enzyme that is normally present in many other parts of the body, and catalyzes one of the steps in the sorbitol (polyol) pathway that is responsible for fructose formation from glucose.
• Modern chewing gum is composed of gum base, sweeteners, softeners/plasticizers, flavors, colors, and, typically, a hard or powdered polyol coating.
• It is widely used to indicate the reactivity of polyol, isocyanate, or epoxy thermoset resins which would undergo crosslinking reactions through those functional groups.
• Otto Bayer (4 November 1902 – 1 August 1982) was a German industrial chemist at IG Farben who was head of the research group that in 1937 discovered the polyaddition for the synthesis of polyurethanes out of poly-isocyanate and polyol.
• It is considerably more stable than glyceryl trinitrate owing to the lack of secondary hydroxyl groups in the precursor polyol.
• The starting materials are similar to those used in polyurethane (PUR) except that the proportion of methylene diphenyl diisocyanate (MDI) is higher and a polyester-derived polyol is used in the reaction instead of a polyether polyol.
• However, if large amounts of glucose are present (as in diabetes mellitus), hexokinase becomes saturated and the excess glucose enters the polyol pathway when aldose reductase reduces it to sorbitol.
• Their product range includes a comprehensive selection of multigrade and monograde polyol ester base stock (Group V) engine and gear lubricants.
• Edson made contributions to the understanding of ketone body metabolism in mammals and birds, metabolic pathways of Mycobacteria, and specificity rules for polyol dehydrogenases.
• It is an cytosolic NADPH-dependent oxidoreductase that catalyzes the reduction of a variety of aldehydes and carbonyls, including monosaccharides, and primarily known for catalyzing the reduction of glucose to sorbitol, the first step in polyol pathway of glucose metabolism.
• Aldose reductase is an enzyme that catalyzes one of the steps in sorbitol (polyol) pathway which is responsible for formation of fructose from glucose.
• After having completely resigned his presidency from Bukaka Group in 1997, he became the owner of GEMA Group holding some joint venture companies such as PT Bayer Urethanes Indonesia (polyol manufacturer), PT Gema SemCorp Engineering (steel fabricator), PT Dowell Anadrill Schlumberger (cementing services and rental equipment for drilling on oil and gas), plus the publishing companies Warta Ekonomi and Mobil Motor.
• In organic synthesis, among its many applications, it is particularly useful in directing regioselective O-alkylation, acylation, and sulfonation reactions for diols and polyol.
• He was responsible for the development of propellants based on HEF20, ISRO polyol, PBAN, CTPB and HTPB for launch vehicles.
• TME is an intermediate in the production of alkyd and polyester resins, powder coating resins, synthetic lubricants based on polyol esters, stabilizers for plastics, plasticizers, and pigment coatings based on titanium dioxide.
• Silver nanocubes can be synthesized using ethylene glycol as a reducing agent and PVP as a capping agent, in a polyol synthesis reaction (vide supra).
• cundurango (synonym Marsdenia cundurango) is known to contain conduritol, a cyclitol or cyclic polyol.
• Gallotannins are polymers formed when gallic acid, a polyphenol monomer, esterifies and binds with the hydroxyl group of a polyol carbohydrate such as glucose.
• 1975 Otto Bayer – head of the research group at IG Farben that discovered the polyaddition for the synthesis of polyurethanes out of polyisocyanate and polyol.
• These compounds are formed by reacting the polyol component with an isocyanate compound, typically toluene diisocyanate (TDI); methylene diisocyanate (MDI) and hexamethylene diisocyanate (HDI) are also widely used.
