Question

Sugar fructose is present in the secretion of
A)Prostate gland
B)Perineal gland
C)Cowper’s gland
D)Seminal vesicles

Answer 1

The fructose is a sugar found naturally in the fruits, fruit juices, some vegetables and honey. Also the fructose is a basic component in table sugar and high-fructose corn syrup which is used to sweeten many processed foods and beverages.

Complete answer:
The fructose is a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and the galactoses that are absorbed directly into the blood during the process of digestion. The male accessory glands include the paired seminal vesicles. The seminal vesicle is narrow with the muscular tissue in its wall, lying between the urinary bladder and the rectum. The sugar fructose is present in the secretion of the seminal vesicle. The fructose is an energy source used by the sperm. This fluid is called as the semen.

The sixty percent of semen is produced by the seminal vesicles.
The seminal vesicle's secretion constitutes the bulk of the seminal fluid. It is the fluid that consists of the sugar fructose, proteins, citric acid, inorganic phosphorus, potassium, and also the prostaglandins. The fluid from the seminal vesicles is viscous and also contains the fructose which provides an energy source for the sperm; the prostaglandin contributes to the mobility and viability of the sperm; and proteins that cause slight coagulation reactions in the semen after the ejaculation. The fructose makes up to ninety nine percent of the reducing sugar present in the semen. This sugar is produced inside the seminal vesicles. The fructose test is not part of a routine semen analysis; also it is useful in cases of azoospermia.

Hence, the correct answer is option (D)

Note: The fructose was discovered by the French chemist Augustin-Pierre Dubrunfaut. The name "fructose" was coined by the English chemist William Allen Miller. The dry and pure fructose is a sweet, white, odorless, crystalline solid, and is the water-soluble of all the sugars. The fructose can be found in honey, tree and vine fruits, flowers, berries, and most of the root vegetables.
