what is meaning of non polar tail and polar head...
why they are arranged in that manner (importance)
Answers
Answer:
The Phosphate group is the negativity-charged polar head , which is hydrophilic.The fatty acid chains are uncharged,nonpolar tails, which are hydrophobic .
Since the heads are hydrophilic ,they gave outwards and are attracted to the interacellular and extracellular fluids .(sandwich laminar theory)
Answer:
Water makes up for ~50-60% of the adult human body. It is present in all tissues, and is an important medium for which most biochemical processes occur. With this information in mind, we can discuss how phospholipids interact in water, and thus conclude how a phospholipid bilayer is formed.
Phospholipids are a class of organic molecules with a hydrophilic head consisting of a phosphate group, which is connected by a glycerol molecule to two long fatty-acid chains that are hydrophobic. They form the cell membrane of human cells.
Before I continue, I'd like to point out the two unusual words used above, and look at their roots.
They both have the prefix, hydro-, which is a Greek word meaning water.
That leaves us with the two suffixes, -philic and -phobic, which are again, Greek in origin, and are in a sense, opposites.
-philic pertains to attraction. For example, I am from Britain, but now live in the U.S. and I find that many people here are Anglo-philes ; that is, they love English people - or more likely, they love my accent.
-phobia pertains to fear. Not everybody in the U.S. understands British people, and so treat me with a certain level of disdain. I deem those people to be Anglo-phobic.
Therefore,
hydrophilic = water-attracted
