Question

Glycosidic linkage in maltose/amylose is
a. \[\alpha 4 \to 1\]
b. \[\beta 4 \to 1\]
c. \[\alpha 1 \to 4\]
d. \[\beta 1 \to 4\]

Answer 1

Hint: A kind of covalent bond which joins a carbohydrate molecule to every other group is referred to as a glycosidic bond or glycosidic linkage. It is able to or may not be every other carbohydrate. In well known, within the middle of the hemiacetal or hemiketal organization of a saccharide and the hydroxyl institution of some compound which include an alcohol, a glycosidic bond is formed.

Complete answer:
- The maltose is likewise known as maltobiose or malt sugar. possible define maltose as a disaccharide which is fashioned from units of the glucose molecules that are joined with an \[\alpha (1 \to 4)\] bond.
- A polysaccharide product of α-d devices of glucose, and bonded to every difference through \[\alpha (1 \to 4)\] glycosidic bonds are known as amylose. Its miles said to one of the things which can be made of starch. It makes up approximately 20-30%.
- The disaccharide which is normally shaped by using the linkage of alpha 1,4 molecules within the glucose is called maltose. The enzyme maltase is able to digest this sugar.
- The glycosidic bonds of the maltose are acted upon by means of it. in flip, they're able to convert them into less complicated compounds. The hydrolysis of this bond can be further processed with its help.
- It's far able to change the maltose to the monomer unit of the glucose. But, however, its miles are located in germinating slightly sufficient.

Hence, the correct answer is option (C).

Note: It's far said that the helical shape of amylose that is typically tightly packed because of the motive that the molecules of amylose are extra proof against digestion than every other starch molecule. As a result, they are handled to be essential sorts of resistant starch. You can still say that the maltose is the unit of two members of the collection of amyloses homologous. For this reason, it is the key structural motif of starch.
