Sidney Udenfriend et 6 al.

Mar 1, 1971 in Clinical Pharmacology & Therapeutics
DR. UDENFRIEND. One thing quite clear from the foregoing discussion, not directly related to parkinsonism and the treatment with levodopa, is that scientists and clinicians are developing a sophistication in the application of biochemistry to pharmacology and therapeutics to a degree they had not realized before. This, I think, is probably one of the best examples of the continuing use of esoteric...

A PERSONAL ACCOUNT OF MY RESEARCH ON COLLAGEN AND FIBROSIS

Sidney Udenfriend

Jan 1, 1976
Publisher This chapter presents a personal account of Sidney Udenfriend on collagen and fibrosis. It highlights a personal account of some of these studies including some details of Sidney`s training that are relevant to research on collagen. the chapter prsents some of the personal interactions with other scientists in the field, those with whom Sidney collaborated, those with whom Sidney compe...

BIOSYNTHESIS OF THE ENKEPHALINS: PRECURSORS AND INTERMEDIATES

Alvin S. Stern et 9 al.

Jan 1, 1980
Several polypeptides that comprise at least part of the biosynthetic pathway of the enkephalins have been isolated from bovine adrenal chromaffin granules. They range in size from enkephalins extended at the carboxy-terminus by a basic amino acid up to a protein of greater than 50,000 daltons containing at least 7 [Met]enkephalin sequences and 1 [Leu] enkephalin sequence. A number of these polypep...

Proenkephalin and the Products of Its Processing: Chemistry and Biology

Sidney Udenfriend, D L Kilpatrick

Jan 1, 1984
Publisher This chapter describes the chemistry of proenkephalin and the products of its processing. The purpose of studies described in the chapter was to characterize the EC peptides in the chromaffin granules and compare them with the β-endorphin-related products from the anterior pituitary gland. In what subsequently became a general procedure, purified chromaffin granules from approximately ...

[87] 5-Hydroxytryptophan and derivatives

Sidney Udenfriend, Herbert Weissbach

Jan 1, 1963 in Methods in Enzymology
Publisher This chapter describes the preparation and purification of 5-hydroxytryptophan and its derivatives. 5-Hydroxytryptamine has been found in many tissues including the gastrointestinal tract, brain, blood platelets, skin, and lungs, and it is the hydroxyindole found in the largest quantities in animal tissues. Biosynthesis proceeds from tryptophan through 5-hydroxytryptophan, and the majo...

[176] Collagen proline hydroxylase (rat skin)

RobertE. Rhoads et 3 al.

Jan 1, 1971 in Methods in Enzymology
Publisher This chapter focuses on collagen proline hydroxylase (Rat Skin). In animal tissues, hydroxyproline is found in only one protein, collagen. Although it has long been known that proline is the precursor of hydroxyproline, only recently has it been shown that the hydroxylation of proline occurs in peptide linkage during or after the formation of the polypeptide chains. The enzyme that con...

6 – PROTEINS AND PEPTIDES

Sidney Udenfriend

Jan 1, 1969
Publisher This chapter discusses proteins and peptide. It also discusses the application of fluorometry as an investigative tool in protein chemistry. Fluorometry has been used to assay the protein content of biological mixtures either through the native fluorescence resulting from tryptophan or following interaction of the protein with specific reagents. The former method is a simple way of mon...
