What is the chemical formula of a trisaccharide made of three bonded glucose molecules?

Each glucose molecule has the chemical formula C6H12O6. When three glucose molecules bond, they lose two molecules of water. The chemical formula of a trisaccharide made of three bonded glucose molecules is C18H32O16.


How do you draw the formula for lactose?

To draw the structural formula for lactose, start with a glucose molecule. Attach a galactose molecule to the glucose molecule through a beta-1,4 glycosidic bond. This forms the disaccharide lactose.


General formula of disaccharides?

The general formula of disaccharides is C12H22O11, representing two monosaccharide units joined together through a glycosidic bond. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).


What formula represents trans isomer?

The general formula for a trans isomer is (E)-X-Y, where X and Y represent different groups attached to the double bond in a non-cyclic structure. The "E" notation indicates that the substituents are on opposite sides of the double bond.

HCl, NH3, PH3, HF, CS, H2CO, H2O have Lewis formulas that do not incorporate a double bond. CS2 has a Lewis formula with a double bond between the C and S atoms.


What bond is broken when maltose is converted to glucose?

The glycosidic bond between the two glucose molecules in maltose is broken during the conversion to glucose. This bond is hydrolyzed by the enzyme maltase, which catalyzes the reaction.


What is the formula for a bond?

If you're talking about formula like chemical formula (NaCl), there isn't one exactly, though sometimes a line is used (single line for a single bond, double line for a double bond, triple line for a triple bond). If you mean like a mathematical formula (LCAO or something similar), then Levine's Quantum Chemistry has a much more thorough treatment than we could possibly give here.


Which combination of bonds is present in the molecule whose formula is written as OO?

The bond indicated by the sign "=" in the formula, which in this instance is not an "equals" sign, is a double covalent bond between the two oxygen atoms.


Which hydrocarbon series contains a double covalent bond between carbon atoms?

The hydrocarbon series that contains a double covalent bond between carbon atoms is the alkene series. Alkenes have the general formula CnH2n and are characterized by the presence of at least one double bond between carbon atoms in the molecule.


Which structural formula represents 4 electrons shared between two atoms?

A covalent bond that shares four electrons has a double bond between the atoms. A single bond is shown as a single dash, so a double bond is two dashes.
