The native structure of hemoglobin (hb) comprises of two α and two β subunits, each of which carries a heme group. there appear

to be no previous studies that report the in-vitro folding and assembly of hb from highly unfolded α and β globin in a 'one-pot' reaction. one difficulty that has to be overcome for studies of this kind is the tendency of hb to aggregate during refolding. this work demonstrates that denaturation of hb in 40% acetonitrile at ph 10.0 is reversible."

If each subunit of a hemoglobin protein molecule carries a heme group and a hemoglobin protein molecule is made of four subunits, two α and two β, we can simply multiply four (number of heme groups that can be found in one hemoglobin protein molecule) by three (number of hemoglobin protein molecules considered). 4×3=12

There are twelve heme groups in three hemoglobin protein molecules.

Further Explanation:

Hemoglobin molecules:  

Hemoglobin, additionally spelled hemoglobin, iron-containing protein in the blood of numerous creatures in the red platelets (erythrocytes) of vertebrates, that transports oxygen to the tissues. Every hemoglobin particle is comprised of four heme gatherings encompassing a globin gathering, framing a tetrahedral structure.  

Hemoglobin protein molecules:  

Hemoglobin is the protein that makes dark red. It is made out of four protein chains, two alpha chains and two beta chains, each with a ring-like heme gathering containing an iron particle. Oxygen ties reversibly to these iron iotas and is shipped through blood.  

Which protein is found in hemoglobin:  

The name hemoglobin is gotten from the words heme and globin, mirroring the way that every subunit of hemoglobin is a globular protein with an installed heme gathering. Every heme gathering contains one iron iota, that can tie one oxygen particle through particle initiated dipole powers.  

Ordinary hemoglobin types include:  

• Hemoglobin A (Hb A): makes up about 95%-98% of hemoglobin found in grown-ups; it contains two alpha (α) chains and two beta (β) protein chains.  

• Hemoglobin A2 (Hb A2 ): makes up about 2%-3% of hemoglobin found in grown-ups; it has two alpha (α) and two delta (δ) protein chains.

Why do we group artworks with similar characteristics into periods or styles?
fgiga [73]
We group artworks with similar characteristics into periods or styles because it is easiest to do it that way - this way we can find common characteristics in these literary/artistic eras, and name them. For example, the Renaissance had a distinct style, which differs greatly from that of Romanticism.
