Molecules in sugars trigger taste receptors on the tongue. In animals, taste determines whether the food has protein or starches that are required in the diet. These will be preferentially consumed.

Sugar is sweet because when our tongue detects a sugar molecule the nervous impulse it sends says "sweet". Our tongue detects the sugar molecule by its shape. The shape fits into a molecule in the surface of a taste bud, and when they bind, it causes the nerve to fire and send a message to the brain that says "sweet". A lot of money has been spent developing new molecules that will cause this molecular response and yet not provide the same calories as actual sugars. The chemicals have to taste sweet, but not be digestible and so have no calories. Nutrasweet, for instance.
However, scientists have been studying the reasons why the nerve impulse means "sweet" to the portion of the brain that receives the impulse.
Ribose sugar which is a pentose sugar .
Deoxyribose
The sugar component in DNA is deoxyribose, hence the name deoxyribonucleic acid. This sugar molecule forms the backbone of the DNA double helix structure.
Yes, DNA molecules contain a sugar called deoxyribose, which is a key component of the DNA backbone.
No, glycerol is not a component of the cell membrane structure. Glycerol is a simple sugar alcohol that is a key component of lipids such as triglycerides. Cell membranes are primarily composed of lipids, proteins, and carbohydrates forming a phospholipid bilayer.
Sugar is not a component of lipids but a component of carbohydrates.
Sugar is not a component of lipids but a component of carbohydrates.
No, sugar is not a component of a nucleotide. Nucleotides consist of a sugar molecule, a phosphate group, and a nitrogenous base.
Ribose sugar which is a pentose sugar .
Ribose
Ribose
yes
no .
Sugar is the basic component and in most cases the largest component in candy.
No, sugar is not a component of lipids. Lipids are organic molecules that include fats, oils, and waxes, while sugar is a type of carbohydrate. Lipids are made up of fatty acids and glycerol, while sugars are composed of carbon, hydrogen, and oxygen atoms.
Water and then sugar.
