What else can I help you with?
Why do hunters kill polar bears?
They kill Polar bears due to their own ignorance. The Polar bear population was listed as "threatened" by the US Department of the Interior in 2008.
What is the interior portion of a cell membrane forms a non polar zone?
glucose
What is cold dry masses that flow into the United Stated from the interior of Canada?
Continental Polar
Where in a protein is a hydrophobic amino acid?
in the interior as they are hydrophobic, don't like to have contact with water (hydropyllic,polar)
What are the names of some the shows that were on The Disney Channel when it first launched?
Mickey MousedumboThe polar exspress
Which of these is hydrophobic like the interior of the plasma membrane?
Lipids, specifically phospholipids, are hydrophobic like the interior of the plasma membrane. The tails of phospholipids are non-polar and repel water, making them ideal for forming the hydrophobic interior of the membrane.
What are lipids with polar heads and nonpolar tails called?
Lipids with polar heads and nonpolar tails are called phospholipids. They are a major component of cell membranes, with the polar heads facing the aqueous environment and the nonpolar tails forming the interior of the membrane.
What are cold dry air masses that flow into the US from the interior of Canada called?
It's Continental Polar.
Who is the decorating show host who often said who knew?
Christopher Lowell. His first show on the discovery channel was Interior Motives.
Are polypeptides polar or non polar?
Both. 1. proteins are polymers with individual subunits (amino acids joiled together in amide linkages) which may be highly polar, highly non-polar, or intermediate. The most polar or non-polar parts are the "side chains". 2. proteins usually fold with the polar side chains out toward the water and the non-polar side chains toward the interior. But there are usually polar groups in the interior as well. The main chain of amide bonds fundamentally polar but is quite happy to be buried in the interior because the polar groups associate to make the "secondary structures" such as helices ("alpha") or sheets ("beta") 3. some proteins have patches of non-polar surface exposed - these are often involved in binding other proteins, membranes, non-polar molecules, etc. 4. some proteins, such as some storage proteins and intrinsic membrane proteins, have large areas of non-polar surface.
How do polar molecules cross the cell membrane?
Polar molecules cross the cell membrane through a process called facilitated diffusion, where they move with the help of specific transport proteins embedded in the membrane. These proteins create channels or carriers that allow polar molecules to pass through the hydrophobic interior of the membrane.
IS VALINE POLAR OR NON-POLAR?
Valine is classified as a non-polar amino acid. Its side chain consists of a branched hydrocarbon structure, which lacks significant electronegative atoms that would create polarity. As a result, valine tends to be hydrophobic and prefers to be found in the interior of proteins, away from the aqueous environment.
