(A). Invert Sugar |
(II). Sucrose |

(B). Milk Sugar |
(I). Lactose |

(C). Dextrose |
(IV). Glucose |

(D). Ketohexose |
(III). Fructose |
(A) Invert Sugar → Sucrose
Invert sugar is obtained when sucrose is hydrolysed into glucose and fructose. During this process, the optical rotation changes (gets “inverted”), hence the name invert sugar. Therefore, its source is sucrose.
(B) Milk Sugar → Lactose
Lactose is naturally present in milk, so it is commonly called milk sugar.
(C) Dextrose → Glucose
Dextrose is simply another name for glucose, especially referring to its dextrorotatory (right-rotating) form.
(D) Ketohexose → Fructose
A ketohexose is a six-carbon sugar containing a ketone group. Fructose is the most common example of a ketohexose.
