ApoE3

ApoE3, or Apolipoprotein E3, is a protein that plays a crucial role in lipid metabolism and the transport of cholesterol in the body. It is one of the three main forms of apolipoprotein E, with ApoE2 and ApoE4 being the others. ApoE3 is considered the most common and efficient variant, helping to maintain healthy cholesterol levels and support cell communication in the brain. Variants like ApoE4 are linked to a higher risk of Alzheimer's disease, while ApoE3 is generally associated with a lower risk, highlighting its importance in brain health and overall well-being.
