DEFINITION

Classification: 530/385

Hemoglobins or globins:

(under subclass 380) Proteins having the structure of hemoglobins or globins and compounds derived from these by addition to or deletion of parts of the polypeptide structure.

(1) Note. Physical Properties. Globin from normal adult human hemoglobin consists of four polypeptide chains: two alpha-chains and two beta-chains. The alpha-chain contains 141, the beta-chain 146 amino acids. Abnormal globins may contain gamma and delta-chains. [figure]

(2) Note. Physiological properties. At pH values near

neutrality, combines with ferroprotoporphyrin to yield hemoglobin, or with ferriprotoporphyrin yield methemoglobin.

(3) Note. Examples. Leshemoglobins, Uteroglobins. Hemoglobin Synonyms: Blood pigments, Ferrohemoglobins Hbs, Hb, Deoxyhemoglobins, Eryhem, Erythrocruorins carboxyhemoglobin.

(4) Note. CA Registry Number of Hemoglobins: 9008-02-0* [figure]
