    HOW ARE REDOX REACTIONS DIFFERENT? Redox is the term used to label reactions in which the acceptance of an electron (reduction) by a material is matched with the donation of an electron (oxidation). A large number of the reactions already mentioned in the Reactions chapter are redox reactions. Synthesis reactions are also redox reactions if there is an exchange of electrons to make an ionic bond. If chlorine gas is added to sodium metal to make sodium chloride‚ the sodium has donated an electron

    with exception of the 5th carbon which is linked to a methyl-hydroxyl group. D-Glucose has 4 chiral centers when it is in ring form which the anomeric carbon appears at C1 which lead to the structure of α(axial‚ down) and β(equatorial‚ up) position 2. The ratio of this anomer exists within the aqueous state of α: β is 36:64 and interconvert with each other within a timescale. This process is called Mutarotaion2. Both anomers can be linked to other sugars but differently as the α-glucose resemble
