Hämoglobin
= Hb
Red blood
cells (erythrocytes) (in human blood) get their red color from hemoglobin.
Other types of blood use different pigments and come in a variety of colors
(green/blue).
Remarkable
feature of blood is its high capacity for carrying O. This is possible by a
metal-containing pigment, which is attached to the blood's protein. The pigment
combines reversibly with O, picking it up in lung/a gill and carrying it to the
cells before letting it go. This process works because the pigment combines
with O at high partial pressure in the organism's respiratory organ, then
releases it at the comparatively low pressure within cells (Ferr-met. works in 3 functional
realms: 1. as healer and strengthener of nervous tissue, 2. relates to the
biliary system, restraining the overexuberance, 3. working in the rhythmic
cycles/the to and fro of taking up and giving up O by the hemoglobin is an example of this rhythmic
activity of iron).
The most
widely-distributed is Hb, a molecule consisting of a porphyrin ring with a
central iron atom hooked to a clump of protein called globin. Hemoglobin is
found in all vertebrates (except a few Antarctic fish)/in the circulatory
fluids of many invertebrates (annelid worms/many arthropods/some
echinoderms/molluscae/crustacea).
Other
pigments as oxygen-transporters:
Chlorocruorin:
in tubular annelids (Polychaeta)/Solutions of this iron-based pigment are green
when dilute, but vivid red at higher concentrations.
The blood
of one species, Serpula vermicularis (= Bunter Kalkröhrenwurm), is remarkable in that
it uses a dual hemoglobin/chlorocruorin system.
Hemerythrin:
in marine worms/some nematodes/annelids/brachiopods. Blood containing this
pigment is bright pink or violet when oxygenated, but colorless by the time it
reaches the veins.
Vanadium
chromagen: sea squirts/ascidians/tunicates. Usually makes blood apple-green,
though this may change to blue or orange in the presence of different vanadium
oxides.
Pinnaglobin:
brown manganese-based porphyrin, in Pinna squamosa
Vitamin
B12: a cobalt-based porphyrin. Coboglobin blood would be colorless or slightly
pink when oxygen-enriched, but dark yellow or deep amber in the veins. (Like
hemocyanin, hemerythrin and coboglobin are not destroyed by carbon monoxide as
is hemoglobin)
Vergleich: Bilurubin = Abbauprodukt von Hämoglobin (Säuglinge)/= Farbstoff in Galle). Bilirubinstein (enthält Biliburin)
Chlrpl = Hämoglobin-ähnLICH/hat Mg statt Fe als Zentralatom
Hämocyanin (hat Cu statt
Fe/transportiert O in Krebse/Muscheln/Schnecken/Tintenfisch:)
Helx-p. The blood system is open, with blood spaces
and no veins. The pigment is colorless, and is called haemocyanin, which contains copper
Herod-c The blood of the worm = simiLAR to human blood/has
same function of carrying oxygen/has iron-rich hemoglobin as its base
