Application

The solubility of α-elastin has been applied to construction of elastin-mimetic biomaterials.

Biochem/physiol Actions

Oxygen transporter. The Fe2+/Fe3+ balance is a physiological indicator of blood oxygenation; deoxygenated hemoglobin accessorizes a feedback loop by reducing nitrite to NO, a vasodilator which enhances blood flow to oxygen-deprived tissues.

Caution

Since native hemoglobin is readily oxidized in air, these preparations may be predominantly methemoglobin.

The supplementary motor area (SMA) has been regarded as a third speech area. The SMA is anatomically classified into two regions, pre-SMA and SMA proper, but the functional specialization of speech production between the two regions remains unknown. Although word
