(The exact percentages vary depending whether it is arterial or venous blood). Most of it (about 70%) is converted to bicarbonate ions HCO − 3 by the enzyme carbonic anhydrase in the red blood cells by the reaction CO 2 + H 2 O → H 2 CO 3 → H + + HCO − 3; about 7% is dissolved in the plasma; and about 23% is bound to hemoglobin as ...

Blood agents work through inhalation or ingestion. [2] As chemical weapons, blood agents are typically disseminated as aerosols and take effect through inhalation. Due to their volatility, they are more toxic in confined areas than in open areas. [1] Cyanide compounds occur in small amounts in the natural environment and in cigarette smoke ...
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but which contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. [1] It is the intravascular part of extracellular fluid (all body fluid outside cells).
In other words, the chemical compound would be designated with a capital letter, but specific instances in structures with lowercase. Thus cytochrome oxidase, which has two A hemes (heme a and heme a 3 ) in its structure, contains two moles of heme A per mole protein.
[citation needed] The only non-mammalian animal known to use serine proteases for blood coagulation is the horseshoe crab. [69] Exemplifying the close links between coagulation and inflammation, the horseshoe crab has a primitive response to injury, carried out by cells known as amoebocytes (or hemocytes ) which serve both hemostatic and immune ...
As in many chemical reactions, chemiluminescence starts with the combining of two compounds, say A and B, to give a product C. Unlike most chemical reactions, the product C converts to a further product, which is produced in an electronically excited state often indicated with an asterisk: A + B → C C → D*
This is done by removing the amino acid that blocks the entrance channel to the active site when the proenzyme is not active. There is currently no other known modifications necessary to activate the proenzyme and enable catalytic activity. Conformational differences determine the type of catalytic activity that the hemocyanin is able to ...
