The capability of the binding oxygen molecule, with the heme proteins, is what makes a difference in both the molecules. Haemoglobin is called as tetrameric hemoprotein, while myoglobin is called monomeric protein. Haemoglobin is found systematically all over the body, while myoglobin is found in muscles tissues only. Haemoglobin is made of protein and prosthetic group and is well known for carrying oxygen pigment. It is the most vital part to sustain life as it works in transporting oxygen … [Read more...]

Deoxyribonucleic acid or DNA  is the material that contains hereditary information in all the living beings, these are regarded as a set of genetic instructions used for further developing the organisms and other functions. At the same time, RNA or Ribonucleic acid play the role in protein synthesis and also in the transmission of genetic information. DNA is double helical structure while RNA is single stranded. As the name suggests DNA contains deoxyribose and lacks one oxygen atoms; RNA … [Read more...]

Carbohydrates are soluble in water and are the most abundant dietary source of energy for all living organisms, whereas fats are insoluble in water but soluble in alcohol, ether, etc. Fats are also considered as a chief store of energy. Our body needs ample amount of energy to do 'work', which we get through macromolecules like carbohydrate and fats. Both of them provide energy to the body and are macronutrients which mean carbohydrates and fats are among top three sources of energy for a … [Read more...]
