Are hydrophobic substances polar or non-polar?
nonpolar
Are triglycerides amphiphilic?
No. Because the polar hydroxyls of glycerol and the polar carboxylates of the fatty acids are bound in ester linkages, triglycerides are nonpolar, hydrophobic molecules, that are essentially insoluble in water.
Is olive oil polar?
no, its hydrophobic
Is iodine soluble in glycerol?
Yes, Iodine is soluble in glycerol. Although keep in my that Iodine is nonpolar because it has no dipole charges, but Glycerol is in fact polar. This is most likely explained by the polar and nonpolar tendencies of Glycerol.
Is CH3 hydrophobic?
methyl is hydrophobic because it is non polar. the c-h bonds have little electronegativity difference I believe. water is polar, and nonpolar things don't tend to react or dissolve in polar substances.
What polar molecules are attracted to water?
Hydrophobic molecules do not dissolve in water. This is because water is hydrophilic. Another way to say this is that lipids, which are nonpolar, cannot dissolve in water, which in polar.
Do phospholipids contain hydrogen?
Yes, they do. Phospholipids contain a hydrophilic (polar) head and a hydrophobic (nonpolar) tail. The hydrophilic (polar) head contains the phosphate groups, which account for the reason why the head is polar since each phoshpate has a net charge of -2. The tail consists of long chains of hydrocarbons, which are nonpolar/hydrophobic due to the symmetry of the chains.
What are two parts of lipid?
A head and a tail. The head is hydrophilic (polar) and the tail is hydrophobic (nonpolar) .
What is in a substance that makes it hydrophobic?
Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges. Water is a polar molecule so it tends to be attracted to other molecules that are polar as well. This is often summed up as "like attracts like". Some examples of hydrophobic molecules include fats and oils which are nonpolar because they have large hydrophobic hydrocarbon chains.
Is the glycerol head of a lipid is polar or nonpolar?
glycerin was polar. One day it became non polar. So it depends upon time!!
What are two main parts of lipid?
A head and a tail. The head is hydrophilic (polar) and the tail is hydrophobic (nonpolar) .
Are triglycerides polar or non-polar?
Yes. Like carbohydrates, lipids also contain oxygen, hydrogen and carbon. But unlike COH, they have much fewer oxygen atoms. As a result lipids are said to be saturated with hydrogen atoms making the bonds between atoms non polar convalent. This means that lipids do not disolve in water. This property is know as being hydrophobic
