Question

Which polysaccharide has only ╬▓ 1 4 glycosidic linkages?

Answer 1

14 means?? is that 1,4-linkage? if yes the answer may be maltose. lactose etc.

Answer 2

Amylose has only 1,4 glycosidic linkages.

• Complex carbohydrates known as polysaccharides are made up of monosaccharide repeating units joined by glucosidic linkage.

• Joining the monosaccharides leads to the formation of either linear or branched chains.
• Polysaccharides have the general formula $(C_{6} H_{10} O_{5} )_{n}$, where n is the number of monosaccharide units, which can range from 100 to 2500.
• Polysaccharides can be either branched or unbranched.
• Only alpha 1, 4 linkages are present in unbranched polysaccharides whereas branched polysaccharides have alpha 1,4 as well as alpha 1,6 linkages.
• The final product of the photosynthetic activity, glucose, is converted to starch and stored in various plant parts. Amylose is a variety of starch.
• Unbranched α-D- glucose subunits connected by -1,4 glycosidic linkages make up the amylose polymer.

Therefore, amylose is a polysaccharide that has only 1,4 glycosidic linkages.
