Sugar is made of 2 molecules, glucose and fructose. Glucose is the energy of life. Every cell on the planet can burn glucose for energy. Glucose is so important that if one does not consume it, the liver makes it (gluconeogenesis). Con- versely, dietary fructose, while an energy source...
Now, say you bite into something very sweet, like a piece of leftover candy corn. That snack touching the outside of your exposed dentin has highly concentrated solutes in the form of sugar molecules.假设你在吃非常甜的东西，比如一块吃剩的玉米糖。那些接触到你暴露的牙本质外部的零食含有高度集...
It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP. 【答案】22.B 23.C 24.B 25.A 【解析】 细节理解题。根据第二...
Excess sugar attaches to proteins in your bloodstream and creates harmful molecules called “AGEs,” or advanced glycation end products. These molecules do exactly what they sound like they do: age your skin. They have been shown to damage collagen and elastin in your skin -- protein fibers th...
Let's find out exactly what dietitians have to say about excessive sugar intake and how it impacts your body. 1. Your blood sugar rises Carbohydrates, including sugar, quickly digest and release into our bloodstream. Sugars are one of the smallest molecules of carbohydrates, so they do not ta...

The polymerization of glycogen from glucose molecules is, and energy is in the process. The lipid bilayer molecules do what for the cell? Does the mucous membrane have goblet cells? How does sugar or protein enter the matrix if the inner membrane of the mitochondria is impermeable? What is ...
A buffer is: A)a substance that stabilizes pH B)a protein that catalyzes a faster chemical reaction C)a string of multiple peptides D)a molecule that hydrolyzes sugar molecules What is AIBN ? What is an alpha-amino acid? What are the monomers of Buna-N?
You would have to undergo medical testing to find out whether you have increased permeability in your intestines.5To test for this issue, medical personal typically would have you ingest a solution containing different sized sugar and other molecules that the intestines usually don’t absorb and th...
Sugar Doesn't Really Melt Ice It's a little inaccurate to say that sugar melts ice. What actually happens is that it lowers the freezing point, so water can stay in the liquid state at a colder temperature. It does this by providing space between the water molecules and reducing their at...
