Sickle cell anemia

Upstream causes

Mutation of DNA, Genetic disorder

Nucleotide error in the DNA

Family history of sickle cell aneia

Background information

Physiology

Anatomy

Destruction of red blood cell

Direct cause

Hemoglobin

Hemoglobin no oxygen, hemoglobin polimerization

Cells

Multiple organs domage

Rapid heart beat

Weakness and and fatigue

Abdominal changes

Damaged internal organs due to ischemia, hypoxia, enlarged liver and spleen

Liver dysfinction, yellowing of body, jaundice

Loss of water in urine,

proteinuria, low absorption and filtration

Abdominal changes

domge interne organs due to ischemia

Liver defection,yellowing of body, jaundice

Pain crisis/sickle cell crisis due to obstruction of blood, painful swelling of fingers, toes

Macromolecules

Quarternary structure

Two or more polypeptide chains connected by
intermolecular interactions

tertiary structure

3 dimensional model due to
intermolecular interactions
between amino acids forming a
polypeptide chain

Secondary structure

Alpha helix, beta sheets and beta turns

Primary structure

Sequence of amino acids

Clumped hemoglobin

sickle cell shaped red blood cells

Indirect cause

Error in the DNA

Hemoglobin S are sensitive to low oxygen clump together and lead to tissue hypoxia
