# Hemoglobin

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

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

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