Carbohydrates are polar because of their composition. They are composed of organic compounds that are simple like ketones and aldehydes that have polar hydroxyl groups attached.

Are carbohydrates generally polar or nonpolar?
they are polar
Why are most simple carbohydrates soluble in water and insoluble in liquids such as hexane?
Because water is polar and hexane is non polar which makes it insoluble
What bond does carbohydrates have?
Carbohydrates are joined by a glycosidic linkage, which is a covalent bond that formed between two carbohydrate molecules by dehydration synthesis.
Why do carbohydrates dissolve so easily in water?
Water is a polar molecule, meaning that the hydrogen end has a negative charge, while the oxygen end has a positive charge. When other polar molecules are exposed to these charges they split apart. In salt the sodium has a positive charge that is attracted to the hydrogen's negative charge, and a the chloride has a negative charge that is attracted to oxygen's positive charge.
Do mono saccharides dissolve well in water?
Monosaccharides will dissolve well in water. This is made possible by the oxygen in the carbohydrates which will create polar bonds.
Do simple carbohydrates dissolve in water?
Carbohydrates do dissolve in water such as salt and sugar but their are other carbs that dont dissovle in water such as cabbages,cellulose, and fructose.
Why is plasma membrane referred to as fluid mosaic model?
it is called that because albert mosaic improved to active the latest model.
Carbohydrates and lipids are very large organic molecules Which two bonds do you expect to find most in these molecules?
ANSWER: nonpolar cavalent bonds and polar covalent bonds
Is cellulose hydrophilic?
I read this somewhere. I think it's non-polar because it is not soluble. It didn't specify soluble in what but I'm assuming it's water. Hence, according to 'like dissolves like' it's non polar because water is a polar substance.
Is carbohydrates soluble in ethers?
Carbohydrates are polar molecules with a lot of -OH functional groups attached to it. This makes them capable of hydrogen bonding, which is one trait of polar protic compounds (molecules that are polar AND can participate in hydrogen bonding). The oxygen of an -OH from one sugar can attract the hydrogen of another sugar, and thus two hydrogen bonding interactions occur for every pair of -OH molecules. These are most soluble in water or other polar protic solvents. Ethers are aprotic solvents (lacking hydrogens), yet it still has some ability to dissolve partially polar molecules. It has an oxygen to attract other hydrogen molecules with, but it does not share a hydrogen at the same time. Therefore, carbohydrates will most likely undergo two bonding interactions with each other via rather than bond to the oxygen molecule of an ether. As a result, you will see a clumping of sugar in ether.
Describe how molecules such as carbohydrates and lipids are important in homeostasis?
carbohydrates are a key source of energy while lipids are non polar or mostly insolube in water so both of them play an important goal in homeostasis
What are the active medicinal properties of kelp?
Phenolic compounds, mucopolysaccharides, algin, polar lipids, and glycosyl ester diglycerides. Kelp also contains protein, carbohydrates, and essential fatty acids.
