what are the three main groups of carbohydrates?
1574
Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.

Simple carbohydrates Sugars can be categorised as single sugars (monosaccharides), which include glucose, fructose and galactose, or double sugars (disaccharides), which include sucrose (table sugar), lactose and maltose.

Carbohydrates are polyhydroxy aldehydes or polyhydroxy ketones OR compounds which give aldehydic as well as ketonic groups on hydrolysis. Therefore the major functional groups are (carbonyl) Aldehyde, Ketone, and hydroxy groups.

Carbohydrates are classified into three subtypes: monosaccharides, (mono- = ”one”, “alone”; saccharide = “sugar, sweet”) disaccharides (di = “two”), and polysaccharides. (poly- = “many, much”). Monosaccharides and disaccharides are also called simple carbohydrates, and are generally referred to as sugars.

Carbohydrates consist of the elements carbon (C), hydrogen (H) and oxygen (O) with a ratio of hydrogen twice that of carbon and oxygen. Carbohydrates include sugars, starches, cellulose and many other compounds found in living organisms. In their basic form, carbohydrates are simple sugars or monosaccharides.

The seven major classes of nutrients are carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. Nutrients can be grouped as either macronutrients or micronutrients (needed in small quantities).

It's also helpful to have some knowledge of the difference between the two types of carbohydrates: simple carbs that are found in everything from table sugar to fruit, and complex carbs, or starches, that occur in foods such as whole grains and starchy vegetables like sweet potatoes.

Alongside fat and protein, carbohydrates are one of the three macronutrients in our diet with their main function being to provide energy to the body. They occur in many different forms, like sugars and dietary fibre, and in many different foods, such as whole grains, fruit and vegetables.

There are three types of molecules used to build the cell: Proteins, carbohydrates and: lipids. Starch, cellulose, glycogen, and polypeptides are all made from chains of many sub-units, or building blocks.

A Carbohydrate Can Be a Simple Carb or a Complex Carb Carbohydrates, often referred to as just “carbs,” are your body's primary energy source, and are a crucial part of any well-balanced diet. The three main types of carbohydrates are sugars, starches, and fiber.

What are the three types of carbohydrates? Simple carbs (sugar), complex carbs (starches, these are better for you!) and fiber.

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell's dry mass (recall that water makes up the majority of its complete mass).
972451
Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks. Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs.
1451554
Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides). The most common types of disaccharides—sucrose, lactose, and maltose—have 12 carbon atoms, with the general formula C12H22O11.

1. Introduction. Alongside fat and protein, carbohydrates are one of the three macronutrients in our diet with their main function being to provide energy to the body. They occur in many different forms, like sugars and dietary fibre, and in many different foods, such as whole grains, fruit and vegetables.
