A rough analogy is when the oil in your car's engine is dirty and needs changing, it gets blackened, thick and sludgy. Thickened bile can't flow well. Since your intestines REQUIRE bile to stimulate movement, poor bile flow causes lack of peristalsis, which equals constipation.
A water molecule measure approximately 2.75 angstroms, making it one of the smallest of all molecules. One meter is 10 billion angstroms. The water molecule is shaped like a V, with two atoms of hydrogen extending at an angle of around 104 degrees from an atom of oxygen. Continue Reading.
Polymers are large molecules composed of repeated chemical units. The smallest repeating unit is called a mer. Linear polymers are like ropes. For a polymer chain of 10,000 units (a typical length), a standard half-inch-thick rope would be about 128 meters (140 yards) long to represent the length-to-thickness ratio.
