Hemoglobin

                                                                       F.L. Hünefeld 

F.L. Hünefeld discovered hemoglobin in 1840 when he observed bright-red crystalline structures in earthworm blood under a microscope.

Felix Hoppe-Seyler's 

Investigated the chemistry of the red blood pigment. He coined the term hemoglobin and demonstrated how it binds oxygen to form oxyhemoglobin.

Hans Fischer

German chemist Hans Fischer won the 1930 Nobel Prize in Chemistry for mapping the structure of heme (the iron-containing pigment in blood) and showing that it features an iron atom at the center of a large porphyrin ring system 

Max Perutz

Max Perutz used X-ray crystallography to determine the molecular structure of hemoglobin, the blood protein that carries oxygen. It took him over 20 years of research to solve the complex structure, earning him the 1962 Nobel Prize in Chemistry.

Ribose and ATP

    Ribose is a five-carbon monosaccharide (pentose sugar) with the formula C₅H₁₀O₅. 

                                                   

                                                                          ATP

ATP (adenosine triphosphate) contains:

Adenine + ribose + three phosphate groups

The ribose-containing molecule adenosine forms the foundation of ATP

Eleks Test

1950 – L. J. Elek introduced the in vitro precipitation test for determining toxin production by C. diphtheriae. This became known as Elek’s test.

Elek’s test is based on immunodiffusion:

Diphtheria toxin + diphtheria antitoxin → visible precipitin line

A strip of filter paper containing diphtheria antitoxin is placed on an agar plate. The suspected C. diphtheriae strains are streaked perpendicular to the strip.
