Epinephrine Synthesis, Adrenergic Receptors & Pharmacology

Medicine and health sciences6.64 KB

Epinephrine and Norepinephrine Synthesis

The synthesis pathway for catecholamines like norepinephrine and epinephrine is as follows:

  1. Phenylalanine is converted to Tyrosine.
  2. Tyrosine is taken into the neuron via a transporter.
  3. Tyrosine is converted to L-DOPA by the enzyme Tyrosine Hydroxylase. (This is the rate-limiting step in the pathway).
  4. L-DOPA is converted to Dopamine by the enzyme Dopa Decarboxylase.
  5. Dopamine is transported into a vesicle via the Vesicular Monoamine Transporter (VMAT).
  6. Inside the vesicle, Dopamine is converted to Norepinephrine by the enzyme Dopamine Beta-Hydroxylase.
  7. Synthesis may stop at Norepinephrine, depending on the cell type.
  8. In the adrenal medulla, Norepinephrine can be further converted to Epinephrine by the enzyme Phenylethanolamine

Understanding Organ Transplants and Donation

Medicine and health sciences2.32 KB

Organ Transplants and Donation

Organ Transplants:

consist of replacing organs, tissues, cells that do not function properly in one organism (the recipient) with others that do not function properly from the same or another body (the donor). Bone marrow are currently transplanted for leukemia patients, in addition to transplanting tissues such as skin and organs such as the heart, kidney, liver, or lungs. In most transplants, the donor is a different person; sometimes the donor is also the recipient. This type is called autologous transplant. Sometimes it is an animal xenotransplantation.

Transplant Rejection:

occurs when the recipient's immune system attacks to prevent rejection. Comparable donors are sought, and the patient has to undergo treatment
