Answer» Solution :(a) Isoelectric point : Itis the pH at which+veand -vecharges on zwitter ion areequal. (b) Mutarotation: It is a spontaneous changeisoptical rotationwhenan optically ACTIVE substanceis dissolvedin WATER . Example`alpha`- glucose ,when dissolvedin water , then itsoptical rotationchanages from `111^(@)`to ` 52.5^(@)` . (c) ENZYMES: Enzymes are biocatalysts whichspeedsup thereactions in biosystem . Theyarehighly specificand selectivein their ACTION . Chemically all enzymes are proteins. |
