Disaccharide, tseem hu ua ob lub suab thaj, txhua yam khoom uas muaj ob molecules ntawm cov suab thaj yooj yim (monosaccharides) txuas rau ib leeg. Disaccharides yog crystalline dej-soluble compounds.
disaccharide yog dab tsi?
A disaccharide muaj ob suab thaj koom nrog O-glycosidic daim ntawv cog lus. Peb qhov ntau disaccharides yog sucrose, lactose, thiab m altose (Daim duab 11.11).
Puas yog disaccharides ob monosaccharides?
A disaccharide (tseem hu ua ob lub suab thaj lossis biose) yog qab zib tsim thaum ob lub monosaccharides koom nrog glycosidic txuas. Zoo li monosaccharides, disaccharides yog cov suab thaj yooj yim soluble hauv dej. Peb qhov piv txwv yog sucrose, lactose, thiab m altose.
Puas muaj pes tsawg monosaccharides nyob rau ntawm disaccharide?
Disaccharides yog oligosaccharides uas muaj ob monosaccharide units.
Puas yog disaccharides yog carbohydrate?
Ib qho disaccharide yog a carbohydrate lossis qab zib uas muaj ob lub monosaccharides koom ua ke los ntawm glycosidic bond (los yog glycosidic linkage). Monosaccharides yog qhov tseem ceeb tshaj plaws hom carbohydrate. Glycosidic bonds yog covalent bonds uas tuaj yeem tsim ntawm pawg hydroxyl ntawm ob monosacccharides.
