Is glucose water soluble?

The below article talks about glucose and its general characteristics, along with some frequently asked questions about the same. 

Is glucose water soluble?

Glucose is soluble in water, and it is due to the presence of oxygen or the -OH group which facilitates hydrogen bonding exceedingly well. The large number of polar hydroxyl groups which are capable of bonding with water molecules is the reason why glucose can readily dissolve in water.

Glucose is a sugar with the chemical formula C6H12O6 and is the most abundant carbohydrate in the world. It is mainly made by plants and some algae during the process of photosynthesis and is formed through carbon dioxide and water, with energy from sunlight. In plants and such organisms, glucose is used to form cellulose which is crucial to forming cell walls. Glucose is the primary and most important source of energy in every living organism. In plants, it is usually stored in the form of starch and amylopectin, whereas in animals it is observed in the form of glycogen. Glucose circulates in animals through blood and is referred to as blood sugar. 

Glucose is a naturally occurring element and is usually found in its free state either in fruits or in other parts of a plant, whereas in animals, glucose is released as a result of a process called glycogenolysis; which is essentially a breakdown of glycogen in the animal body, which gives out glucose. 

Purposes and Sources of Glucose 

Glucose is mainly used to treat low blood sugar and is also used as an immediate fuel source in the form of carbohydrates. Glucose can also be attained from various other food sources including bread, grape juice, honey, dried fruits, agave, molasses, fruits, fruit juices, etc. 

Frequently Asked Questions (FAQs): What is glucose used for?

What are the recommended glucose levels?

  • If it is a random test for blood sugar, > 200 mg/dL or > 11.1 mmol/L, could mean they are diabetic. 
  • If an individual is getting tested following an overnight fast, < 100 mg/dL or < 5.6 mmol/L is considered normal; Between 100 and 125 mg/dL or 5.6 to 6.9 mmol/L is considered pre-diabetic; and anything > 126 mg/dL or 7 mmol/L on two separate tests, would indicate diabetes. 
  • For an oral glucose tolerance test, < 140 mg/dL or 7.8 mmol/L is normal, > 200 mg/dL or 11.1 mmol/L within 2 hours would indicate diabetes, and reading between these two levels at the same time would indicate the individual is pre-diabetic. 

What are some causes and symptoms of low blood sugar?

Causes would include: 

  • Ingestion of high doses of insulin
  • When the body does not receive adequate amounts of carbohydrates 
  • Changes in timing to medications or changes in any medications 
  • Changes to patterns of physician activity 
  • Food patterns and portions, especially ensuring the right nutrients are provided to the body 
  • Changes to the weather 
  • Behaviors such as drinking or a drug use

Symptoms of low blood sugar would be:

  • Rapid heartbeat 
  • Chills 
  • Shakes and sweating 
  • Anxiety 
  • Irritability 
  • Dizziness
  • Nausea and/ or hunger
