Carbohydrates vs. Proteins: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 28, 2023
Carbohydrates are organic compounds mainly used for energy, while proteins are complex molecules essential for structure and function in living organisms.

Key Differences

Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, primarily serving as a key energy source. Whereas, proteins, composed of amino acids, are complex molecules crucial for the structure, function, and regulation of the body's tissues and organs.

The primary role of carbohydrates in the diet is to provide energy, particularly through glucose. Proteins, however, serve a variety of functions including building and repairing tissues, making enzymes and hormones, and supporting immune function.

Carbohydrates are classified as simple (sugars) or complex (starches and fiber), affecting the body’s glucose levels differently. In contrast, proteins are made up of twenty different amino acids, some of which are essential and must be obtained through diet.

The digestion of carbohydrates begins in the mouth and is quickly converted into glucose. Protein digestion is more complex, starting in the stomach and requiring more time to break down into amino acids.

Excess carbohydrates can be stored as fat, while excess protein can lead to kidney strain and loss of calcium. Both nutrients, however, are vital for the human body, each playing distinct roles in health and metabolism.

Proteins

Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.
