Royal Jelly

Bee venom is a nutritious, viscous substance produced by the secretory glands of worker bees. It serves as the primary nutritional source for the queen bee and young larvae. This secretion has significant biological effects that determine the development and differentiation of individuals within the bee colony.

Physical Properties

Fresh bee venom has a yogurt-like consistency and a homogeneous structure. Its color is pale beige or yellowish-white. It has a distinctive sharp, phenolic odor and a characteristic sour taste. Its density is approximately 1.1 g/cm³ and it is soluble in water. Its pH ranges between 3.4 and 4.5, making it an acidic substance.

Its properties can deteriorate rapidly upon exposure to sunlight, moisture, heat, and air. Therefore, it is recommended to store it frozen to preserve its quality.

Chemical Composition

The chemical composition of bee venom is complex and may vary depending on the conditions of production. Its main components are water, proteins, sugars, lipids, vitamins, and minerals.

• Water: Contains approximately 57–70% water.
• Proteins: Makes up approximately 9–18%. A significant portion consists of a group known as Major Royal Jelly Proteins (MRJPs), which play a crucial physiological role in queen development. It also contains gammaglobulin, a substance that inhibits the growth of bacteria and viruses.
• Sugars (Carbohydrates): Accounts for approximately 7–18%. Contains sugars such as fructose, glucose, maltose, and trehalose.
• Lipids (Fatty Acids): Makes up approximately 3–8%. The most distinguishing feature of bee venom compared to other bee products is its fatty acid content. The best-known of these is 10-hydroxy-2-decenoic acid (10-HDA), which is accepted as a standard for determining the quality of bee venom.
• Vitamins: Contains all B-group vitamins, as well as vitamins C, D, and E.
• Minerals: Contains various minerals such as phosphorus, sulfur, sodium, potassium, calcium, and iron.

Importance to Bees

The most fundamental role of bee venom within the bee colony is to determine the development and differentiation of individuals. Although there is no genetic difference between queen bees and worker bees, all morphological and physiological differences between them arise entirely from diet. Diploid larvae fed exclusively on bee venom throughout their development become queens, while larvae fed bee venom for the first three days and then a mixture of nectar, honey, and pollen become workers. This dietary difference directly affects the development duration, lifespan, and physiology of the bees. For example, while the queen completes her development in 16 days, the worker bee takes 21 days. The queen can live up to three to four years, whereas worker bees live only six to seven weeks during the active season. Additionally, the queen’s ovaries develop fully and she can lay 1500–2000 eggs per day, while the worker bees’ ovaries remain undeveloped. Depending on diet, reproductive organs develop in the queen, while structures such as pollen baskets, strong mandibles, brood food glands, and wax glands develop in the worker bees.

Importance to Humans and Bioactive Properties

In addition to its nutritional properties, bee venom is regarded by humans as an important product due to its bioactive components. It possesses functional properties such as antioxidant, antimicrobial, anti-inflammatory, and anti-aging effects. These effects are believed to originate from the proteins, peptides, lipids, and phenolic compounds contained in bee venom. Research has indicated that bee venom may support cell renewal and influence metabolism and the immune system. It has also been reported to have hypolipidemic and antihypertensive effects, as well as vasodilatory activity. Due to the presence of insulin-like peptides, it also exhibits hypoglycemic effects. Because of these properties, it is traditionally and in modern apitherapy practices used as a dietary supplement and as a supportive agent against various ailments. It has also been reported to be used for skin and hair health, loss of appetite, and irregular nutrition. Due to its medical applications, the use of bee venom in forms such as powder, capsules, or paste available on the market must always be consulted with a physician.
