Proteins oxygen-carrying

FIGURE 6.7 The three-dimensional structures of two proteins that contain substantial amounts of rx-helix in their structures. The helices are represented by the regularly coiled sections of the ribbon drawings. Myohemery-thrin is the oxygen-carrying protein in certain invertebrates, including Sipunculids, a phylum of marine worm. (Jane Richardson)... [Pg.165]

The oxygen-carrying function is performed in some invertebrates by haemerythrin which, in spite of its name, does not contain haem. It is a diiron-oxygen protein. See K. K. Anderson and A. Gralund, Adv. Inorg. Chem. 43, 359-408 (1995). [Pg.1102]

ERYTHROCYTES. Erythrocytes are biconcave diskshaped, blood cells (with pits or depressions in the center on both sides), the primary function of which is to transport hemoglobin, the oxygen-carrying protein. The biconcave shape of the erythrocyte provides a large surface volume ratio and thereby facilitates exchange of oxygen. The average diameter of erythrocytes is 7.5 pm, and thickness at the rim is 2.6 pm and in the center about 0.8 pm. The normal concentration of erythrocytes in blood is approximately 3.9-5.5 million cells per pL in women and 4.1-6 million cells per pL in men. The total life span of erythrocytes in blood is 120 days. [Pg.562]

Erythrocytes—Red blood cells the color comes from the oxygen-carrying protein hemoglobin inside the cell. [Pg.153]

L. B. Mendel and H. C. Bradley found in 1905 diat the snail syco-typus contains zinc in the fiver and in die oxygen-carrying protein of the blood, liemosycotypin. The diree respiratory proteins, hemoglobin of the vertebrates, hemocyanin of die octopus, and hemosycotypin of the... [Pg.151]

An example of evolution via gene duplication is provided by the oxygen-carrying proteins of blood. [Pg.17]
