blood pigment

In the process, he described methaemalbumin, a previously unknown blood pigment.

Oxygen is carried by the blood pigment hemocyanin.

Even the blood pigment is an analogue of hemoglobin, though the metal base isn't iron, of course.

In a severe infection, the ability of the lobster's blood pigment haemocyanin to carry oxygen may be reduced by up to 50%.

Cysts may be lined by osteoclasts and sometimes blood pigments, which lend to the notion of "brown tumors."

There are a few names and conditions which may pertain to this, such as hematochromatosis, or staining of tissues with blood pigment.

Recent studies have shown that sugar molecules tend to be incorporated abnormally into many proteins of diabetic patients, including the blood pigment hemoglobin.

Hoppe-Seyler was the first scientist to describe the optical absorption spectrum of the red blood pigment and its two distinctive absorption bands.

Between 1895 and 1901 he co-operated with Marceli Nencki in research about the content of ammonia in blood and conversions of blood pigment.

In molluscs and crustacea copper is a constituent of the blood pigment hemocyanin, which is replaced by the iron-complexed hemoglobin in fish and other vertebrates.

But it can bind to another part of the blood pigment, to the tail of an amino acid called cysteine, which is present in each of the two beta units of a hemoglobin molecule.

Here he worked with the Professor of Chemical Pathology, Claude Rimmington, in learning the techniques which were to underpin his future research studies on the blood pigment haem and its relation to the disease porphyria.

The new discovery is that another part of the hemoglobin, a segment of its protein chain known as a cysteine residue, can also hold and release nitric oxide, giving the blood pigment the ability to regulate local levels of nitric oxide in the circulatory system according to need.
