D-GLUCOSE A ME NA MONOSACCHARIDE E PILI ANA E like me na mea maka

NO NA ALKYL POLYGLYCOSIDES

Ma waho aʻe o ka D-glucose, he mau mea hoʻomaka hoihoi paha kekahi mau kōpaʻa pili no ka synthesizing alkyl glycosides a i ʻole alkyl polyglycosides. Pono e ʻōlelo kūikawā ʻia i nā saccharides D-mannose, D-galactose, D-ribose, D-arabinose, L-arabinose, D-xylose, D-fructose, a me L-sorbose, e kū pinepine ana ma ke ʻano a i ʻole hiki ke hana ʻia. hana ʻia ma kahi ʻoihana. Loaʻa iā lākou ma nā kumukūʻai haʻahaʻa haʻahaʻa a no laila hiki ke loaʻa maʻalahi e like me nā mea maka no ka synthesis o surfactant alkyl glycosides, ʻo ia hoʻi nā alkyl D-mannosides, alkyl D-galactosides, alkyl D-ribosides, alkyl D-arabinosides, alkyl L-arabinosides, alkyl xylosides, alkyl D-fructosides, a me alkyl L-sorbosides.

ʻO D-glucose, ka mea i ʻike ʻia he glucose, ʻo ia ke kō kaulana loa a me ka mea maʻamau maʻamau. Hoʻopuka ʻia ia ma kahi ʻano ʻoihana ma o ka hydrolysis starch. ʻO ka ʻāpana D-glucose ka mea nui o ka mea kanu polysaccharide cellulose a me ka starch a me ka sucrose home. No laila, ʻo D-glucose ʻo ia ka mea koʻikoʻi nui e hiki ke hoʻololi hou ʻia no ka synthesis o nā surfactants ma ke ʻano ʻoihana.

Hiki ke hoʻokaʻawale ʻia nā Hexoses ʻē aʻe ma waho o D-glucose, e like me D-mannose a me D-galactose, mai nā mea kanu hydrolyzed. Loaʻa nā ʻāpana D-Mannose i loko o nā polysaccharides mea kanu, i kapa ʻia he mannanes mai nā nati ʻelepani, ka palaoa guar, a me nā hua carob. ʻO nā ʻāpana D-Galactose kahi mea nui o ka lactose kōpaʻa waiu a loaʻa pinepine ʻia i ka gum arabic a me nā pectins. Hiki ke loaʻa maʻalahi kekahi mau pentoses. Loaʻa ka D-xylose i ʻike nui ʻia ma ka hydrolyzing i ka polysaccharide xylan, hiki ke loaʻa i ka nui mai ka lāʻau, mauʻu, a i ʻole nā ​​pūpū. ʻIke nui ʻia ʻo D-Arabinosa a me L-arabinose ma ke ʻano he mea hoʻohui o nā ʻōpala mea kanu. Hoʻopaʻa ʻia ʻo D-Ribose ma ke ʻano he ʻāpana saccharide i nā waikawa ribonucleic. No ka keto[1]hexoses, D-fructose, he mea hoʻohui o ke kō a i ʻole ka beet sugar sucrose, ʻo ia ka saccharide kaulana loa a hiki ke loaʻa. Hana ʻia ʻo D-Fructose ma ke ʻano he mea ʻono i nā nui nui no ka ʻoihana meaʻai. Loaʻa ʻia ʻo L-Sorbose ma kahi ʻenehana ʻoihana ma ke ʻano he huahana waena i ka wā o ka hana ʻenehana o ka ascorbic acid (vitamin C).
