Dirghayu: December 2008
http://dirghayuved.blogspot.com/2008_12_01_archive.html
Saturday, December 6, 2008. Proteins are one of the chief constituents of all living matter. Biological activity of each protein is characterized by the total number of amino acids and the sequence in which they are arranged and the overall three dimensional structure of a molecule. Analysis of proteins and enzymes of blood are used to diagnose disease, eg. Plasma protein electrophoresis and plasma albumin;Globulin ratio is a part of liver function test. BIOLOGICAL IMPORTANCE OF PROTEINS-. Metabolism is ...

Monday, January 26, 2009. Difference between fats, waxes and oils. B) Very Low Density Lipoproteins. C) Low Density Lipoproteins. D) High Density Lipoproteins. Phosholipids are the compound lipids and are esters of fatty acids withglycerol containing an esterified phosphoric acid and nitrogen base. They are present in large amounts in nerve tissue, brain, liver, kidney, pancreas and heart. 1) They increases the rate of fatty acid acid oxidation. 3) They help blood clotting.

Dirghayu: September 2010

Monday, September 6, 2010. Factors influencing plasma level of Calcium-. 1) Parathroid hormone- It increase calcium absorption from ileum in the presence of vitamin D. 2) Vitamin D- It enhances absorption of calcium from the intestine and thus maintains the normal plasma calcium concentration. 3) Plasma proteins- As mentioned above nearly half of the blood calcium is bound to plasma protein will be accompanied by the decrease in the total calcium level.

Dirghayu: February 2009
http://dirghayuved.blogspot.com/2009_02_01_archive.html
Friday, February 27, 2009. Many enzymes catalysed the reaction of their substrate only in the presence of a specific organic molecule called co-enzyme. Folic acid acts as a coenzyme for transfer and utilization of formate C1 fragment in the form of tetrahydrofolic acid. It is used in the treatment of macrocytic anaemia. It takes part in purine nucleotide synthesis and thymidylate synthesis. Folic acid consist of pteridine nucleus, P aminobenzoic acid and glutamic acid. Biochemical role of vitamin B12-.

http://dirghayuved.blogspot.com/2010_10_01_archive.html
Tuesday, October 5, 2010. Titany is disease that occurs due to decreased ionized fraction of serum calcium which may be due to-. A) An increase in the PH of blood. B) Poor absorption of calcium from the intestine. C) Decreased dietary intake of calcium. D) Increased renal excretion of calcium as in nephritis. E) Increased retention of phosphorous as in renal tubular disease. Subscribe to: Posts (Atom). Click here for hum1. View my complete profile.

Dirghayu: July 2010
http://dirghayuved.blogspot.com/2010_07_01_archive.html
Monday, July 5, 2010. Factors which influence blood calcium level-. The entire blood calcium is confined to plasma since erythrocyte membrane is impermeable to calcium ions. The plasma calcium whose total content is 9-11mg/100 ml, in three different forms. A) Ionized-which is diffusible through membrane and capillary wall. B) Non ionized protein bound-which is combined with plasma proteins and not pass through the capillary wall. Subscribe to: Posts (Atom). Click here for hum1. View my complete profile.

Friday, March 20, 2009. Biochemical role of calcium-. Calcium is the principle mineral and is an essential constituent of the cell and has following function in the body-. 1) Calcium along with phosphorous is essential for the formation of the developments of bones and teeths. 2) Ionized calcium is required in blood coagulation process. 3) It regulates the excitability of nerve fibers and nerve centers. 5) It is required for maintaing the integrity of intracellular material.
