Biosynthesis of prostaglandins from arachidonic acid in guinea pig lung. Prostaglandins and related factors. 38.

The prostaglandins constitute a class of physiologically active compounds with a widespread occurrence in animal tissues (see References 2 and 3). Previous studies have led to the determination of their structures (4-S), and more recent investigations have shown that they can be formed enzymatically from the essential fatty acids (7,8). It was thus shown that in homogenates of vesicular glands ...

Isolation and Identification of Prostaglandins from Human Seminal Plasma. 18. Prostaglandins and Related Factors.

A depressor substance which stimulates smooth muscle was discovered by Goldblatt and von Euler in extracts of human seminal plasma and of the vesicular glands of sheep (1,Z). The active principle, called prostaglandin, wm shown to have acidic properties. Investigations on its occurrence and biological effects were carried out by von Euler (2) and more recently by El&son (3). Two biologically ac...

Prostaglandins: a report on early clinical studies.

The prostaglandins are a unique group of pharmacologically active lipids which are widely distributed in mammalian tissues and body fluids. The chemistry of this family of compounds has been established in elegant detail. Research quantities of these highly active natural compounds were obtained by enzymatic bioconversion of essential fatty acids and now studies devoted to the elucidation of th...

Prostaglandins

Knowledge of the structure and synthesis of antibodies (immunoglobulins) has developed to a remarkable degree in the last decade. Distinct classes of immunoglobulin (yG, yM, -yA, yD, yE, and their subgroups) have been identified and shown to consist of fixed numbers of light and heavy polypeptide chains organized in pairs. Each polypeptide has a segment of variable amino acid sequence; the spec...
