Carbohydrates

Carbohydrates

by Kevin Ahern, PhD

This section will focus on carbohydrates, the primary source of energy for most living organisms. Students will learn the nomenclature of polysaccharides, be able to identify the most common carbohydrate structures, and understand how different carbohydrates are used in various biochemical pathways.

Errors in the Video
By Peddi A. on 12. October 2023 for Saccharides โ€“ Simple Carbohydrates

The following are the errors in the information you provided: 00:24 The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. 01:15 The structural formula for lactose is C12H22O11. This means that it is a disaccharide made up of two monosaccharides, glucose and galactose. 01:39 Polysaccharides are polymers of monosaccharides, but they do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure. Here is a corrected version of the information you provided: Carbohydrates are molecules whose name literally means hydrates of carbon. This is because monosaccharides, the simplest carbohydrates, have a ratio of one carbon atom to two hydrogen atoms to one oxygen atom, the same as water. The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. Disaccharides are carbohydrates that are made up of two monosaccharides. They are formed by a glycosidic linkage between the two monosaccharides. Disaccharides have the general formula C12H22O11. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose). Polysaccharides are carbohydrates that are made up of many monosaccharides. They are formed by glycosidic linkages between the monosaccharides. Polysaccharides have the general formula (C6H10O5)n, where n is the number of monosaccharides in the polysaccharide. Examples of polysaccharides include cellulose, starch, glycogen, and chitin. Polysaccharides do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure.

 
excellent
By Maymoona W. on 29. April 2023 for Lipid Links โ€“ Complex Carbohydrates

it's very easy and simply explained and I loved it It was very helpful

 
Great
By Ian P. on 28. November 2020 for Polysaccharides โ€“ Complex Carbohydrates

Magnificent lecture about polysaccharides and their functions for storage and release

 
Essential lecture materials
By Lisa R. on 25. August 2020 for Common Sugars: Nomenclature & Structure โ€“ Simple Carbohydrates

Concise and clear; exactly what I needed for this topic, thank you.
