Answer:
Usually, the length of the cell edge is represented by a.
The direction from a corner of a cube to the farthest corner is called body diagonal (say bd).
Face diagonal = fd
bd^2 = 3a^2
Atoms along the body diagonal (say bd) touch each other. Thus, the body diagonal has a length that is four times the radius of the atom, R.
bd = 4 r
The relationship between a and R can be worked out by the Pythagorean theorem:
4R=3a

Answer:
A glycosidic bond or glycosidic linkage is a type of covalent bond that joins a carbohydrate molecule to another group, which may or may not be another carbohydrate. A glycosidic bond is formed between the hemiacetal or hemiketal group of a saccharide and the hydroxyl group of some compound such as an alcohol.
