What else can I help you with?
Are polysaccharides polar?
Yes, polysaccharides are polar molecules because they contain multiple hydroxyl (-OH) groups, which create regions of partial positive and partial negative charge along the molecule. This polarity allows polysaccharides to interact with other polar molecules through hydrogen bonding.
What happens to polar bodies during the process of oogenesis?
During oogenesis, polar bodies are small cells that are produced as a byproduct of egg cell formation. They contain genetic material but eventually disintegrate and are not involved in fertilization.
Do phospholipids contain polar tails and nonpolar head groups?
The compound with both a non-polar tail and a polar head is called an amphiphilic molecule. An amphiphilic molecule can form micelles. These such micelles is how detergents dissolve dirt. A big example of micelles are phospholipids.
Are polar bodies visible in a cats ovary?
Yes, polar bodies can be seen in a cat's ovary during oogenesis. Polar bodies are small cells that contain genetic material expelled during the process of forming an egg cell. They play a role in reducing the genetic material in the egg to facilitate fertilization.
Glucose dissolves in water because?
Glucose dissolves in water due to both the solute, Glucose, and the solvent, H2O, are both polar. Polar atoms have an uneven distribution of charges, so they can dissolve easily in other polar solvents. Non polar atoms, such as CH4, need a non-polar solvent to dissolve in. Non-polar means that the charge is evenly distributed, so non-polar atoms will not dissolve in polar solvents.
Why do the livers of seals contain a large amount of vitamin A?
Liver contains high levels of vitamin A, and because polar bears subsist largely on seals, including seal liver, their own livers are loaded with vitamin A.
How much vitamin A does a polar bear's liver contain?
A polar bear's liver contains between 24,000 and 35,000 IU per gram. The tolerable upper level of vitamin A intake for a healthy adult human is 10,000 IU. This is why eating a polar bear's liver can kill a human due to the massive amount of vitamin A it contains.
What animal liver would kill you of vitamin A poisoning?
Polar bear liver
Can animals be poisoned by liver?
Yes, if the liver is putrid it could poison an animal. Also the livers of some animals (eg that of a polar bear) contain so much vitamin A that if a human ate it (humans are animals) they would get vitamin A poisoning.
Is creatine polar?
Yes, It is. Creatine is created by the liver and kidneys from three amino acids. The polar interactions contain hydrogen bonds.
Can you eat black bear liver?
They are endangered species....no one would let you eat an endangered species liver!! Actually polar bears are not endangered. The correct answere is that if you eat polar bear liver you will overdose on vitamin A.
Do polar bears swim in salt or fresh water?
Scince the polar bears live in the arctic, the arctic ocean surrounds the therefore they swim in salt water. Never eat a polar bears liver or you will die because their liver has Vitamin K which is poisonous to humans.
Is vitamin e polar or non polar?
Vitamin A is polar, and vitamin C is as well. Polar molecules interact through dipole, dipole intermolecular forces and hydrogen bonds.
Do humans eat polar bears?
Yes, humans eat polar bears. Many people in the arctic do. As well, many humans use their furs for coats and other uses.Ask people in Alaska, I am sure they do but other polars bears eat each other.Certainly. But beware of the liver, it is very rich in vitamin A, and eating too much has caused the death of polar explorers. -------------------------------------------------- You should not do this because Polar Bears are becoming endangered, but apart from this, while Polar bear meat is sometimes eaten by indigenous people or fed to dogs, frequently the the meat is infected with trichina (a parasite that infects humans) and the liver contains a harmful concentration of vitamin A.
Is vitamin A soluble in hexane?
Yes, vitamin A is soluble in hexane because it is a fat-soluble vitamin. Hexane is a non-polar solvent that can dissolve non-polar substances like fats and oils, making it suitable for dissolving vitamin A.
Can a molecule be non-polar overall but still contain a polar bonds?
yes
Molecule that contain polar bond are always polar molecule?
Yes, it is true.
