                                                                Biochemistry Terms 

Atom -

               Atoms are very small. So there are very small particles. Atoms are not divided any other particles.


Molecules -

                 Molecules is small part of matter and which contain all physical and chemical properties of the matter and has a free existence. 


ATOMIC MASS -  

                            The atomic weight of an element is a number which indicates how many times heavier the atom is in comparision to an atom of another element taken as standard.


Molecular Mass - 

                            The sum of atomic masses of all the atoms present in a which is mass of 1 molecular.


Molar Mass - 

                    The mass of 1 mole of that compound ( gram molecular mass or gram formula mass ) mass of 1 mole particles.


Mole concept - 

                       A mole is a collection of particles or the amount of substance containing particles equal to 1 mole .


Molarity -

                Number of moles of solute 1 liter solution is molarity of the solution .

                                                             No of moles of solution         

                          MOLARITY =  ....................................................................................

                                                                1 liter solution 


Normality-

                  Number of gram equivalents of solute solution is normality of solution .

                                                                       Equvalent 

                 NORMALITY = ...............................................................................

                                                                          in liter


Molality - 

               Number of moles of solute present in 1 kg of solvent . 

                                                        No of moles of solution 

                 Molality = ......................................................................................

                                                             1 liter in solution

ह्यूमन मेटान्यूमोवायरस (HMPV): उपचार, लक्षण और बच्चों और वयस्कों पर प्रभाव

-
ह्यूमन मेटान्यूमोवायरस (HMPV): उपचार, लक्षण और बच्चों और वयस्कों पर प्रभाव ह्यूमन मेटान्यूमोवायरस (HMPV), न्यूमोविरिडे परिवार का हिस्सा है, यह एक श्वसन वायरस है जो हल्की सर्दी से लेकर निमोनिया  और ब्रोंकियोलाइटिस जैसे गंभीर फेफड़ों के संक्रमण तक की बीमारियों का कारण बनता है। हालाँकि फ्लू या रेस्पिरेटरी सिंसिटियल वायरस (RSV) की तुलना में कम पहचाना जाने वाला, HMPV दुनिया भर में श्वसन संबंधी बीमारियों का एक महत्वपूर्ण कारण है, खासकर सर्दियों और वसंत के दौरान। Symptoms of human metapneumovirus include: Cough. Fever. Runny or stuffy nose. Prevention Can you prevent a human metapneumovirus infection? You can reduce your risk of getting HMPV and other  infectious diseases  by: Washing your hands often with soap and water. If you aren’t able to use soap and water, use an alcohol-based hand sanitizer. Cover your nose and mouth — with your elbow, not your bare hand — when you sneeze or cough. Avoid being around other people when you or they are sick with a cold or other contagious ...

                                                                          Blood   Blood :-         Blood is a specialized connective tissue which is fluid in nature.The total volume of blood in the body is about 6 liters. Blood is slightly alkaline with a pH of about 7.4. The specific gravity of blood  is about 1.055. Blood composition:                   Blood is a highly Complex fluid which is composed of two parts a liquid called  the plasma and different types of cells which remain suspended in the plasma. The cells are called the blood corpuscles. The plasma constitutes about 55% and the cell about 45% of the total volume of human blood. The general composition of whole blood is as follows :      ...
