Haemoglobin. By Maja & Jonathan. Protein Functions. Iron-containing oxygen-transporting metallprotein Essential for respiration Located in all red blood cells of vertebrates Around 35% of our blood (including water) Four iron atoms; can bind up to four oxygen molecules
Haemoglobin. Basic Knowledge:. Haemoglobin is an iron protein - compound in red blood cells that transports oxygen, carbon dioxide, and nitric oxide. It carries oxygen to body cells. After releasing oxygen to the body tissues, haemoglobin picks up carbon dioxide and transports it to the lungs.
Haemoglobin. 4 globin chains each with 1 Haem 3 main haemoglobins Hb A Alpha2 Beta2 Hb A2 Alpha2 delta2 Hb F Alpha2 Gamma2 Main purpose to carry O2 --- Haem part
HAEMOGLOBIN ESTIMATION. Sahli’s method. Aim. To estimate the Haemoglobin levels in mg/dl using Sahli’s method. Equipment. Sahli’s haemoglobinometer with tube, pipette, colour comparator and stirrer Hydrochloric acid, 0.1N Distilled water Blood sample. SAHLI’S HAEMOGLOBINOMETER.

Normal Haemoglobin. Always 2 Beta-type and 2 Alpha-type globin chains carrying haem moleculeBeta-typeepsilon, gamma, beta, thetaAlpha-typezeta, alpha. Haemoglobin structure. So functional Hb is always a heterotetramerthere must be 2 Beta and 2 Alpha for oxygen carrying functiondifferent types at different stages of fetal and early neonatal lifeby 6 months we have adult proportions.
Measurement of Haemoglobin. Dr Maliha Sumbul. Hemoglobin ( also spelled haemoglobin and abbreviated Hb or Hgb ) is the iron -containing oxygen -transport metalloprotein in the red blood cells of vertebrates ,  and the tissues of some invertebrates .
Hemoglobin (haemoglobin, Hb, Hgb). red cells in blood carry O 2 from lung to tissues by hemoglobin, a 4-subunit protein having an O 2 -binding prosthetic group, heme, that gives blood its color (Hb also carries (some) CO 2 and H + back to the lung)
Oxygen dissociation curve of haemoglobin. . Objectives : -Understand what is shown by the oxygen dissociation curve. -Be able to describe and explain the significance of the S-shaped curve. -Understand the B ohr effect -Be able to interpret other oxygen dissociation curves. .
