What is the smallest component of a carbohydrate?
The smallest component of a carbohydrate is a monosaccharide or also known as sugar. Some examples of monosaccharides are fructose, glucose, and galactose.
Yes, tomato contains carbohydrate. For the carbohydrate content of tomatoes (small, medium and large), please see the page link, further down this page, listed under Related Questions. The much simplified definition of a carbohydrate is a component of living cells (such as plants) that is a source of energy to animals or humans. Because tomatoes fit this definition, then a tomato is a carbohydrate.
No, immunoglobuline are glycoproteins, they are proteins that bind on the surface of polypeptide chains carbohydrate residues. This means that there is a carbohydrate component in immunoblobulins, but their dominant behavior is that of a protein, even if their sugar part is important in determining their behavior.
No, carbohydrates are NOT a major components of cell membranes, which are mainly comprised of lipid (fat molecules). Proteins sit in and on the membrane and SOME of the proteins are glycosylated, which means that they have sugar or carbohydrate attached to them. So there are carbohydrates in cell membranes, but they are not a major component.
Carbohydrates, proteins and lipids are the three macronutrients that the body uses for fuel and in various biological processes. Carbohydrate and fat are both energy sources, with carbohydrate being the main one. Proteins can be used as enzymes and is the major component of cells, tissues, muscles and many other structures in the body.
