Proteoglycans are proteins that are heavily glycosylated. The basic proteoglycan unit consists of a "core protein" with one or more covalently attached glycosaminoglycan (GAG) chain(s). The point of attachment is a serine (Ser) residue to which the glycosaminoglycan is joined through a tetrasaccharide bridge (e.g. chondroitin sulfate-GlcA-Gal-Gal-Xyl-PROTEIN).

22. Picture...  Wasn't so sure about this since no charge was given, so I suspected it has a charge of 2. If you have more information on this I would be glad to help, and I can't tell what is happening with the calculations given. It would be helpful if you can add spaces or put a line break.

23. An ion is an atom or molecule with an electric charge. It is formed when atoms lose or gain electrons. There are two types of ions: cations (net positive charge) and anion (net negative charge).

A chemical equilibrium exists when: A chemical equilibrium exists when: there are equal amounts of reactants and products. the r
Airida [17]

Answer: A chemical equilibrium exists when the rate at which reactants form products is the same as the rate at which products form reactants.

Explanation:

When the concentration of both the reactants and products do not change with time then it means the chemical reaction has reached to a state of chemical equilibrium.

For example, CO(g) + Cl_{2}(g) \rightleftharpoons COCl_{2}(g)

Therefore, we can conclude that a chemical equilibrium exists when the rate at which reactants form products is the same as the rate at which products form reactants.

How many days are required for 200. grams of radon-222 to decay to 50.0 grams?
Murrr4er [49]
The answer is (3) 7.64 days. The remaining mass of radon-222 is one fourth of the original mass, so two half lives have elapsed (because one half time one half equals one fourth). Each half life of radon-222 is about 3.82 days, so the total time elapsed is 3.82 * 2 = 7.64 days
