Carbohydrates (article) | Chemistry of life | Khan Academy
WEBCarbohydrate chains come in different lengths, and biologically important carbohydrates belong to three categories: monosaccharides, disaccharides, and polysaccharides. In this article, we’ll learn more about each type of carbohydrates, as well as the essential energetic and structural roles they play in humans and other organisms.
5.9: Structure and Function of Carbohydrates - Biology LibreTexts
WEB28 Feb 2021 · Carbohydrates provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. Carbohydrates also have other important functions in humans, animals, and plants.
5.2: Carbohydrate Structures - Chemistry LibreTexts
WEBCarbohydrates are organic compounds that contain only carbon \(\left( \ce{C} \right)\), hydrogen \(\left( \ce{H} \right)\), and oxygen \(\left( \ce{O} \right)\). They contain a chain of carbons, an aldehyde or a ketone, and hydroxyl groups. Every carbon atom is attached to one oxygen atom.

WEB31 Jul 2022 · Identify several major functions of carbohydrates. Most people are familiar with carbohydrates, one type of macromolecule, especially when it comes to what we eat. To lose weight, some individuals adhere to “low-carb” diets.
Structure of the plasma membrane (article) | Khan Academy
WEBCarbohydrates are the third major component of plasma membranes. In general, they are found on the outside surface of cells and are bound either to proteins (forming glycoproteins) or to lipids (forming glycolipids). These carbohydrate chains may consist of 2-60 monosaccharide units and can be either straight or branched.

WEBOther carbohydrates, including cellulose, chitin, and peptidoglycans, are structural molecules. They are formed from long chains of monosaccharides that are cross-linked by hydrogen bonds or peptide bonds into tough, fibrous sheets. Carbohydrates can also be used to build other complex molecules.
Introduction to carbohydrates (video) | Khan Academy
WEBAbout. Transcript. A carbohydrate is a type of molecule that contains carbon, hydrogen, and oxygen. Carbohydrates can be simple sugars (monosaccharides) like glucose, or they can be made up of multiple sugar units (polysaccharides) like glycogen. They are important in biology as a source of energy and as structural components in plants. Questions.
