What are the 4 classes of carbohydrates?
Carbohydrates, or saccharides, are biomolecules. The four major classes of biomolecules are carbohydrates, proteins, nucleotides, and lipids. Carbohydrates are the most abundant of the four. Also known as “carbs,” carbohydrates have several roles in living organisms, including energy transportation.
What to know about simple vs complex carbohydrates?
The Different Types of Carbohydrates Carbohydrates 101. Carbohydrate is one of the three macronutrients in food that provide fuel for the body to function properly. Simple Carbs. Simple carbohydrates are, as the name implies, simple structures. Complex Carbs. Balancing Simple and Complex Carbs.
What is the difference between simple and complex carbohydrates?
Complex carbohydrates take longer to digest and are a more stable source of energy than simple carbohydrates. Complex carbohydrates are present in foods such as bread and pasta. Simple carbohydrates are in foods such as table sugar and syrups. Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates.
Why are carbs so bad?

What are the components of carbohydrates?
Carbohydrates, also known as saccharides or carbs, are sugars or starches. They are a major food source and a key form of energy for most organisms. They consist of carbon, hydrogen, and oxygen atoms. Two basic compounds make up carbohydrates: Aldehydes: These are double-bonded carbon and oxygen atoms, plus a hydrogen atom.
What are the functional groups in carbohydrates?
Other functional groups in carbohydrates are given below, where R is a carbon group, such as -CH3 . Carbohydrates are composed of the elements carbon, hydrogen and oxygen. The carbonyl group consists of the bound C=O and is found in aldehydes, ketones, and as you will see later, carboxylic acids.
