Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. Low hemoglobin levels (anemia) can cause fatigue, shortness of breath, and other symptoms.

iollo markers that associate with Hemoglobin


Alanine is involved in heme biosynthesis, which is necessary for hemoglobin production in red blood cells. Altered alanine levels may reflect impaired heme synthesis and reduced hemoglobin.


Glycine is a precursor for heme biosynthesis. Glycine deficiency can impair heme production and lead to decreased hemoglobin levels and anemia.
