HEMOGLOBIN
HEMOGLOBIN Blood is a connective tissue in form of fluid.Red blood cells (erythrocytes) are the non-nucleated formed elements of blood. While hemoglobin is the iron containing protein in blood that is responsible for the transport of respiratory gases. It is a chromoprotein and has a molecular weight of 68000. Hemoglobin increases oxygen solubility in blood by about a hundredfold. NORMAL HEMOGLOBIN CONTENT;Average hemoglobin content in blood is 14-16 g/dL. The value varies depending upon the age and sex. AGE At birth : 25 g/dL After 3rd month : 20 g/dL After 1 year : 17 g/dL From puberty onwards : 14 to 16 g/dL SEX In adult males : 15 g/dL In adult females : 14.5g/dL. STRUCTURE AND TYPES OF HEMOGLOBIN Hemoglobin is a conjugated protein. Its molecule is globular in shape, and is made up of 4 sub units. It consists of a protein combined with an iron containing pigment. The protein part is globin and the iron containing pigment is heme. Globin;Contains four polypeptide c
