Apolipoprotein B

Apolipoprotein B

Share

Link copied

Apolipoprotein b (apob) is a protein present on the surface of low density, intermediate density, very low density, and chylomicron lipoprotein particles. There is 1 molecule of apob per particle. In fasting samples 90-95% of apob is bound to LDL particles. As a result, apob is used analytically as an estimate of the number of LDL particles.
