Cells have receptors on their surfaces that trap LDL in the bloodstream and then internalize them for cellular use. Their bodies don't have the full mechanism for dealing with cholesterol LDL and as a result they are at very increased risk of heart attacks. O hydrogen bonds result in the formation of an intricate three-dimensional network. Jenkins, of the University of Toronto and colleagues tested a vegetarian diet to lower cholesterol. The terminal ethyl carboxylate group is coplanar with the fused ring system.
A twofold rotation axis passes through the bridgehead C atom. It is a glycoluril derivative with five fused rings.
It is a glycoluril derivative with five fused rings.
, tert-butyl, aryl, bromo and methoxy groups, the former two occupy equatorial positions and the latter two are placed axially on the cyclohexanone ring.
N hydrogen bond stabilizes the molecular structure.
The water molecules participate in extensive hydrogen bonding and link molecules into a two-dimensional network.
No significant hydrogen bonds are observed.
O hydrogen bonds, forming centrosymmetric carboxylic acid dimers. O hydrogen-bonding interactions. All atoms are located on general positions.
O hydrogen-bonding interactions. It is a glycoluril derivative with five fused rings. Plant sterols are molecules found in plants that resemble cholesterol and compete in the intestine with cholesterol for absorption.
, tert-butyl, aryl, bromo and methoxy groups, the former two occupy equatorial positions and the latter two are placed axially on the cyclohexanone ring. They have been demonstrated to lower cholesterol. N hydrogen bond stabilizes the molecular structure. O hydrogen bonds that link adjacent molecules into one-dimensional extended chains. Cholesterol is manufactured in the liver and travels out of the liver aboard lipoprotein particles called VLDL which are then converted to LDL, short for Low Density Lipoproteins.
N hydrogen bonds link molecules into two-dimensional layers.
O interactions, forming dimers in the crystal structure.
O hydrogen bonds that link adjacent molecules into one-dimensional extended chains.
It is a glycoluril derivative with five fused rings. Cells have receptors on their surfaces that trap LDL in the bloodstream and then internalize them for cellular use. Jenkins, of the University of Toronto and colleagues tested a vegetarian diet to lower cholesterol.
Rings A and B and rings B and C are trans-fused, while rings D and E are cis-fused.
O hydrogen bonds, forming centrosymmetric carboxylic acid dimers.
A phenylethynyl-substituted benzene ring is fused to a seven-membered ring, which binds two of the N atoms from separate rings of the glycoluril system.
