Answer:
Lipids are hydrocarbon molecules that make up the structure of living beings. Few examples are <u>fats, oils and waxes</u>. Steroids are also a class of lipids but they are not structurally related to other lipids but do share some common properties with them. They are <em>insoluble in water and are hydrophobic</em>( water-repelling).
Explanation:
Lipids are insoluble in water as they are <em>non-polar</em> but soluble in non polar solvents (<em>chloroform</em>). Fat soluble vitamins like <u>A,D,E,K and steroids</u> have a different structure composed of fused four rings.
The most common example of steroid is cholesterol. Cholesterol acts as a precursor for many hormones and other signalling molecules.
An example of a situation in equilibrium is the amount of money in a bank account never changes.
What is Equilibrium?
Equilibrium is a point where the supply and demand are perfectly equal.
Equilibrium can be of two types:
- dynamic equilibrium
- static equilibrium
Example of equilibrium conditions include:
Chemical equilibrium - this refers to the equilibrium that exists in chemical systems. This form of equilibrium is a dynamic equilibrium where even though conditions in the system remain constant, the molecules in the system are constantly changing.
See-saw equilibrium - this is a static equilibrium where there os no change occurring in the sytem.
An equilibrium state is reached when when the supply and demand is equal such as the case when the amount of money in a bank account never changes.
In conclusion, equilibrium state is constant and never changes.
