Sucrose, a major product of photosynthesis in green leaves, is synthesized by a battery of enzymes. The substrates for sucrose s

ynthesis, D-glucose and D-fructose, are a mixture of α and β anomers as well as linear compounds in solution. Nonetheless, sucrose consists of α-D-glucose linked by its carbon-1 atom to the carbon-2 atom of β-D-fructose. How can the specificity of the glycosidic bond in sucrose be explained in light of the structural diversity of the potential substrates for sucrose synthesis?

Answer:

Sucrose is a disaccharide composed of alpha D gluose and beta D fructose linked together by beta 2,alpha1 glycosidic linkage.

Explanation:

The specificity of glycosidic linkage very much essential to choose the substrate for the synthesis of specific disaccharide.

 For example sucrose contain beta 2,alpha1 glycosidic linkage that means the hydroxyl group of anomeric carbon of one monosaccharide(fructose) should remain in beta conformation and the hydroxyl group of other monosaccharide(glucose) should remain in alpha conformation.

Which of these takes place when a chemical change occurs? option 1: Bonds connecting atoms in products and reactants form. optio
Tamiku [17]

Answer: Out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.

Explanation:

A change that leads to the change in chemical composition of a substance is called a chemical change.

For example, 2NH_{3} \rightarrow N_{2} + 3H_{2}

Here, bond between the reactant atoms nitrogen and hydrogen is broken down.

On the other hand, bond connecting the products that is N_{2} and H_{2} is formed.

Thus,, we can conclude that out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.

Give the nuclear symbol for the isotope of gallium, ga, that contains 40 neutrons per atom. Replace the question marks with the
Cerrena [4.2K]

The nuclear symbol of an element have three parts namely:  

  1. the symbol of an element
  2. mass number of the element
  3. atomic number of the element

The general representation is as:

_{Z}^{A}X

where X is the chemical symbol of the element, A is mass number of the element that is total number of neutrons and protons in the nucleus of an atom, and Z is atomic number of the element that is number of protons in the atom.

Element = Gallium, Ga    (given)

Number of neutrons = 40 (given)

Let the nuclear symbol be _{?}^{?}Ga. So, we need to determine the values of "?" in the symbol.

Atomic number of Gallium, Ga = 31

Since, atomic number = Number of protons.

So, number of protons of Gallium, Ga = 31

Mass number = number of protons + number of neutrons

Substituting the values:

Mass number = 31+40 = 71

So, the nuclear symbol is _{31}^{71}Ga.
