Summary Introduction

a.

To determine:

The subunit structure of hemoglobin molecules marked X, Y, and Z.

Introduction:

Hemoglobin is an essential part of RBCs as it delivers oxygen to all the parts of the human body.

Summary Introduction

b.

To determine:

The normal condition that should increase the hemoglobin percentage in a newborn that is HbZ.

Introduction:

Hemoglobin refers to a protein in RBCs that carries oxygen throughout the body. The hemoglobin is made up of subunits known as heme, which gives the blood its red color.

Summary Introduction

c.

To determine:

The normal condition that should increase the hemoglobin percentage in an adult that is HbY.

Introduction:

A normal adult hemoglobin molecule consists of two alpha globins and two beta globins. Each globin surrounds an iron-containing a small molecular structure called heme group.

Sickle cell anemia is a hereditary disease in which a faulty hemoglobin (Hb S) molecule is produced. A single DNA base change, from adenine to thymine, leads to the substitution of valine for glutamic acid leading to the production of hemoglobin S. Discuss the steps involved in the production of this molecule.
Normal Hgb is referred to as HbA and contains 4 subunits, 2 a-globin chains and 2 B-globin chains, arranged as two dimers of aß. In Sickle Cell Disease, both B-globin chains are altered in the dimers (aßS/aßS). Q3: Which level of structure does the aß/aß and aßS/aßS in HbA and HbS describe?
Normal Hgb is referred to as HbA and contains 4 subunits, 2 α-globin chains and 2 β-globin chains, arranged as two dimers of αβ. In Sickle Cell Disease, both β-globin chains are altered in the dimers (αβS/αβS). Q3: Which level of structure does the αβ/αβ and αβS/αβS in HbA and HbS describe?
