What are Lipids?


Types of lipids in the human body

  • Phospholipids are one type of lipids that are used in cell membranes
  • Steroids are another type of lipid which are also found in the cell membrane in lesser quantity than phospholipids. Steroid create testosterone in males or estrogen in females. Yes these are present naturally in you body to a certain extent. But body builders take excess quantities of it which inhibits body's natural ability to produce correct quantities of the hormone leading to various health complications. Infact Cholesterol is also a steroid molecule. And just like many things in your body it's useful but too much can be a bad thing and that's why if you have too much cholesterol in your body then it get clogged in your bloodstream and whenever this happens the risk of heart attack or stroke increases.
  • Your liver tries to store excess glucose as glycogen. This a good thing as stored glycogen acts as a reserve for energy and we don't have to eat all day. It's pretty cool actually. But whatever is left over and cannot be stored as glycogen; is stored as triglycerides. Triglycerides aren't very good as they go through your bloodstream and get deposited in your adipose tissue. The more adipose tissue you have the fatter you become.
  • There are more types in lipids but these 3 concern us the most.

Effects of Lipid Deficiency

Lets understand the role of lipids. Then we'll be able to say would would happen if we didn't have enough:

  • Store energy; If our body didn't store energy we'd never put on enough weight and would have to eat all day to meet the supply of energy.
  • Provide Insulation / Heat; They protects our organs and burns the energy stored in the lipid molecule to provide heat. If we didn't have enough, we'd get cold very soon and our vital organs would be left unprotected.

Effects of Excess Lipids

  • Your liver tries to store all the glucose as glycogen. This a good thing as, stored glycogen acts as a reserve for energy and we don't have to eat all day. It's pretty cool.
  • However whatever is left over and cannot be stores as glycogen is stored as triglycerides. Triglycerides aren't very good. Triglycerides go through your bloodstream and then their deposited in your adipose tissue.
  • The more adipose tissue you have the fatter you become.
