Yellapragada Subbarow was an indian biochemist who discovered the functions of adenosine triphosphate as a energy source in the cell,and developedmethotrexatefor the treatment of cancer.most of his career was spent in us. Subbarow was also credited with the synthesis of chemical compounds folic acidand methotrexate. A fungus genus was named subbaromyces in his honor.You've probably never heard of DR.Yellapragada subbarow. Yet because he lived you may be alive and are well today.Because he lived ypu may live longer.

Early life and Education
He was born in Bhimavaram,madras presidency ,now in west godavaridistrict Andhrapradeshin india.he passed through a traumatic period in his schooling at Rajahmundry. he passed the intermediate examination from the presidency collage and entered the madras medical collage where his education was supported by his friends and kasturi suryanarayana murthy,whose daughter he later married. subbarow tried to enter the madras medical service with out success.he then took up the job as lecturer in anatomy at Dr.lakshmipathi's ayurvedic collage.he was fascinated by the healing power of ayurvedic medicines and began to engage in research to put ayurvedic on moern footing.The promise of support from Malladi sathyalingam,naicker charitiesin Kakinada,and financial assistance raised by his father in law,enabled subbarow to proceed to us. he arrived in Boston on26 oct 1922.

career in united states
after earning a diploma from the Harvard medical schoolhe joined harvard as a junior faculty member with Cyrus fiske he developed a method for estamination of phosphorusin body fluids and tissues.He discovered the role of Phosphoceratine and Adenosine triphosphatein muscular activity, which earned him a entry in to biochemistryin 1930. he obtained his PHD in same year.He joined Lederle laboratories,a division of American cynamid,after he was denied a regular faculty person at havard.

At lederle he developed a method to synthesize Folic acid,vitamib9, based on wor by Lucky willsto isolate folic acid as a protective agent against Anemia.after his work on folic acid and with considerable input from DR.Sidney farber,he developed the important anti cancer drugMethotrexateone of the first cancerChemotherapy agents. subbarow also discovered Hetrazanwhich was used by the world health organisationagainst Filariasis.under subbarow Benjamin duggar made his discovery of the worlds first [[Tetracycline,Aureomycinin 1945.
