• About Hemoglobin

• Transportation of oxygen is the function of hemoglobin.

• Iron is essential for the formation of hemoglobin.

• Hemoglobin molecule exhibits structural organization of proteins Quaternary Structure.

• Defeciency of Pyridoxine decreases hemoglobin production.

• Heme in haemoglobin is Protoporophyrin IX.

• Infants acquire adult hemoglobin level at End of first year.

• Ferric ion is not a part of hemoglobin molecule.

• Haemoglobin is found dissolved in the plasma.

Explanation

HbF (Fetal Hemoglobin) is predominant in fetuses and newborns, later replaced by HbA.

Explanation

A non-invasive sugar test measures glucose levels without pricking the skin.

It uses technologies like infrared sensors or skin patches to monitor sugar levels painlessly.
