Study Notes

Carbohydrate Structure

Carbohydrates are composed of carbon, hydrogen, and oxygen.
The basic formula for carbohydrates is CH₂O. This means there is one carbon atom, two hydrogen atoms, and one oxygen atom in the ratio.
Carbohydrates are also called hydrates, because the structure includes water.

Carbohydrate Source

Plants create glucose through photosynthesis.
Plants utilize carbon dioxide (CO₂), water (H₂O), and energy from the sun.
The combined reaction of photosynthesis is: 6CO₂ + 6H₂O + Energy (sunlight) → C₆H₁₂O₆ + 6O₂ This produces glucose (a type of simple sugar) and oxygen.

Carbohydrate Foods

Carbohydrates are found in various foods.
Examples include fruits, breads, biscuits, rice, pasta, root vegetables, breakfast cereals, and potatoes.

Carbohydrate Nomenclature

Carbohydrates are polyhydroxy aldehydes or ketones, or their derivatives.
These include D-Glucose and D-Fructose as examples.

Carbohydrate Uses

Carbohydrates are a key source of energy for the body.
They are the main fuel for cells, particularly nerve tissue and red blood cells.
Excess glucose is stored as glycogen in the liver and muscles.
A diet lacking enough carbohydrates may cause the body to utilize proteins for glucose production.

Diseases related to carbohydrates include diabetic ketoacidosis, hyperosmolar coma, and hypoglycemia, which negatively affect the central nervous system.

Carbohydrate Classification

Carbohydrates fall into four main categories: monosaccharides, disaccharides, oligosaccharides, and polysaccharides.
Monosaccharides are simpler sugars.
Disaccharides are formed by two monosaccharides bonded together.
Oligosaccharides have 3-10 monosaccharides bonded together.
Polysaccharides have many monosaccharides bonded together.

Types of Carbohydrates

Carbohydrates can be categorized into simple and complex types.
Simple carbohydrates include monosaccharides and disaccharides. They provide quick energy, but lack vitamins, minerals, and fiber.
Complex carbohydrates include oligosaccharides and polysaccharides, offering sustained energy, vitamins, minerals, and fiber.

Simple Carbohydrates

Simple carbohydrates are found in fruits, milk, and vegetables.
Cake, candy, and other refined sugar products contain simple sugars.
These carbohydrates offer quick energy, but can lack essential nutrients like vitamins, minerals, and fiber.

Complex Carbohydrates

Complex carbohydrates include grains, legumes, rice, and starchy vegetables.
These carbohydrates supply sustained energy and essential nutrients like vitamins, minerals, and fiber.

Carbohydrate Functions

Carbohydrates provide energy to the body, by fueling cells, offering a preferred source of energy for certain cells.
Carbohydrates spare proteins from being broken down for producing glucose, when other glucose sources are not sufficient.
Carbohydrates prevent ketosis by supporting complete metabolism of fats.
Carbohydrates provide fiber, which aids weight management, regulates digestion, and reduces health risks. This includes risks for heart disease and type II diabetes.

Biological Roles of Carbohydrates

Carbohydrates also play a role in nutrient and energy storage.
They also play structural and protection roles.
They act as lubricants in bones, aid in cell adhesion, and are involved in intracellular signaling and cell recognition.
