Answer. There are 6 carbon atoms/molecule of glucose. Avogadro's constant (6.02 * 10^23) represents the number of atoms/molecules in a mole (atoms if it is a pure substance). It is required to takes place in considering 6.022x10^23 molecules.

A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms. The subscripts also indicate the ratios of the elements. A dozen CO2 molecules have one dozen carbon atoms and two dozen oxygen atoms. A million CO2 molecules have one million carbon atoms and two million oxygen atoms.

A chiral carbon is defined as a carbon atom which has 4 different atoms or groups of atoms attached to it which is also known as an asymmetric carbon. There are 4 chiral carbon atoms in the glucose molecule and also four chiral carbons are present in the fructose.

Carbon atoms 1 and 6 have only three different substituents on them. Thus, there are four chiral carbon atoms in the glucose molecule.

C, 13C, and 14C are isotopes of carbon (Z = 6) and therefore contain six protons. If the atoms are neutral, they also must contain six electrons. The only difference between these isotopes is the number of neutrons in the nucleus.

One mole of the glucose molecule (C6H12O6) would yield six moles of carbons atoms, due to there being six of them per molecule. Multiply the moles of glucose present, 0.1 moles in this case, by the number of carbon atoms per molecule, six, to get 0.6 moles of carbon, which translates into about 3.61×10^23 carbon atoms.

There are 3 Carbon atoms in C3H4. The numbers following the Element names (Like C, or H, or Na) is the amount of atoms in the compound. So there are 3 Carbon atoms and 4 Hydrogen atoms.

Saturated fatty acids are straight-chain organic acids with an even number of carbon atoms (Table 2). All saturated fatty acids that have from eight to 16 carbon atoms increase the serum LDL cholesterol concentration when they are consumed in the diet.

In one mole of carbon, there are 6.02×1023 atoms. So in two moles, there will be twice that: 1.204×1024 .

Which statement best describes the function of this enzyme in producing cholesterol? The enzyme speeds up the reaction by reducing the energy of activation, allowing the reaction to proceed to completion. Lipids such as cholesterol are composed of atoms that are chemically bound together by nonpolar covalent bonds.

Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.

A carbon dioxide molecule, which has the formula CO2, contains one carbon atom and two oxygen atoms. This information is contained in the subscripts after each element. A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.

One molecule of glucose has 6 atoms, as you can see in carbon's index. ( C6 ). In 20 molecules there will be 6⋅20 carbon atoms. So, written down like this there are 20⋅6 carbon molecules, 12⋅20 hydrogen atoms and 6⋅20 oxygen molecules.
