DEFINITION

Classification: 530/362

Albumin:

(under subclass 350) Proteins having the structure of albumin and compounds derived from these by addition to or deletion of parts of the polypeptide structure.

(1) Note. Physical Properties: A group of proteins characterized by heat coagulability and solubility in dilute salt solution.

(2) Note. Grain and soybean albumins, as well as all plant albumins are excluded from this subclass and provided for in subclasses 370+.

(3) Note. Albumin refers to egg white or dried egg white. Albumin contains 75 percent ovalbumin, ovoconalbumin, ovomucoid, ovomucin, ovoglobulin, lysozyme and avidin.

(4) Note. Mesh tree number: D12. 776.34 [figure]
