Molecules of life

 In Biology and Biotecnology we study about molecules of life. Today we will discuss about it.

Moleceules of life:-There are four molecules of life.

1 Protein

2Crabohydrate

3LIPIDS

4Amino acids

1 Protein:- Proteins are the building block of living things It gives energy to all living beings. It is very essential for living beings  for development growth,cells functions It helps in repairing  and building tissues of the body. It contains chains of amino acids All the 20 amino acids are found in protein naturally. Protein synthesis in ribosomes of cells. Structure of protiens are very complex  

2 Carbohydrates:-  It gives instant energy to living organism. It contains atoms of carbon hydrogen and oxygen starch ,sugar, fibers are all carbohydrates.  Carbohydrates foun in many natural foods potato rice sugarcane milk fructose found in honey fruits and vegetables 

carbohydrates are classified into three 

1Monosaccrides :-  means one sugar unit  these are simple  carbohydrate they have special roles. 

There are 3 types 

1 Glucose 

2 Fructose

3 Galactose 

1Glucose gives instant energy

2Fructose is sweatest sugar found in honey fruits

3 Galactose found in milk and dairy products 

2 Disaccrides:- are two sugar unites or two jioned monosaccrides . there are two types

1Sucrose:-  this is common kind of sugar found in foods these are sweater.When they are proceed they separated their sugars and gives energy 

2 Lactose:- found in milk products  It is white in colour ,water soluble  Itis mostly used in food industry It is not sweet in taste 

3 Maltose:-  These are commonly malt and are found in mostly cereals  It is found in wheat  barlry  It is also founds in fruits like peaches  plums Function of maltose is digest the food 

3 Polysacchrides :- as its name poly means many or large chains of monosaccrides units contains more than  ten monosacchrides units  they can store starch cellulose, starch andglycogen, chitin are common  examples   

cellulose plant walls is made up of cellulose 

Glycogen madeof large chains of molecules and stored energy in animals. 

3Chitin:- madeup of chains of glucose found in animals exoskeleton insects fungi etc 

Lipids :- lipids are generally fats ,oils waxs  vitamins  A D E K, sterols it is structural and functional block of living beings  Its function is to store energy  they are not soluble in water these also have types .

4 Amino acids they are total 20 amino acids It contains carboxyl functional groups They are building block of proteins  carbon hydrogen oxygen nitrogen are present their function is synthesis of harmones, neurotransmeter  All 20 amino acids are useful for us
