Different species have different physiology and transfusion requirements, but most vertebrates share hemoglobin-based oxygen transport.
Across vertebrate species, oxygen transport shares a common molecular foundation in hemoglobin.

Heme and chlorophyll belong to the tetrapyrrole family. Their metals, ring structures and side chains differ.
Hemoglobin transports oxygen. Chlorophyll absorbs light in photosynthesis.

Animal health and species protection are at the heart of our initiative.
Explore the initiativeHemoglobin binds oxygen through iron-containing heme groups. Oxygen delivery also depends on circulation, oxygen affinity, blood flow and tissue demand.
Hemoglobin-based oxygen carriers, or HBOCs, investigate a cell-free approach to oxygen transport. BHOC builds on this field as a Biological Hemoglobin Oxygen Carrier development platform. The objective is complementary oxygen-delivery support, not replacement of the wider functions of blood.
Most vertebrates use hemoglobin, with important exceptions such as Antarctic icefish. Conserved chemistry is a scientific starting point; species-specific physiology, dosing, safety and efficacy still require their own evidence.
Both belong to related tetrapyrrole chemistry. Heme coordinates iron; chlorophyll coordinates magnesium. Their ring structures, side chains and biological roles differ. Hemoglobin transports oxygen; chlorophyll absorbs light in photosynthesis.
