A hydrophobic hydrocarbon made up of carbon (C) and hydrogen (H). It is usually very large molecule that will not mix with water making it hydrophobic. If you try to mix oil and water the two don't mix.
2) Lipids are not made from small subunits into a long molecular chain. Lipids are not polymers.
Simple lipids:
1) Neutral fats & oils are triglycerides (3 fatty acids attached to a single glycerin). Esters of three molecules of fatty acids plus one molecule of glycerol; the fatty acid may all be different. The nature of the lipid triglyceride depends on the fatty acid chains.
Triglycerides are found in insulating adipose tissue and as a compact energy source in butterfat, lard, suet, fish oils, olive oil, corn oil, etc.
2)Lipid Waxes (bee honey-combs, plant cuticle coating, hair coating like lanolin) serve as surface coatings to provide protection or lubrication.
Compound lipids:
3) Steroids (cholesterol -> aldosterone, cortisone, testosterone, progesterone and estrogen) Cholesterol’s carbon skeleton with four fused rings is a precursor for biosynthesis of sex hormones and a critical membrane constituent.
4) Phospholipids and glycolipids (cell membrane compound lipids)are amphipathic diglycerides with a phosphate head group so they are not neutral.They have a polar end making them form a bilayered membrane.
Answer:
There are five principles of fitness out of which two are overload principle and rest and recovery principle. Overload principle is one of the most important principle which tell that to gain and improve the fitness one should do the hard work.
Slowly and gradually the intensity and time of exercise are increased so that our body can adapt to the hard work. Overload principle plays an important role in improving the skills and improving performance during exercise and sports.
Rest and recovery principle is important to relax the body and release the stress that happens due to intense training like in case of weight lifting one day rest should be taken to repair and rebuild the muscles. This allows the body to encounter the fatigue and improve performance.
