Overview

What is he best known for?

The fields of study he is best known for:

  • Enzyme
  • Biochemistry
  • Amino acid

His primary areas of study are Biochemistry, Endocrinology, Internal medicine, Enzyme and Chromatography. His study in Biochemistry is interdisciplinary in nature, drawing from both Molecular biology and Stereochemistry. As part of one scientific family, Sidney Udenfriend deals mainly with the area of Endocrinology, narrowing it down to issues related to the Serotonin, and often Tryptamine.

His study on Enzyme is mostly dedicated to connecting different topics, such as Tryptophan. The Chromatography study combines topics in areas such as Urine and Fluorescence, Fluorescamine. His studies in Fluorescamine integrate themes in fields like Reagent and Primary.

His most cited work include:

  • Fluorescamine: A Reagent for Assay of Amino Acids, Peptides, Proteins, and Primary Amines in the Picomole Range (2292 citations)
  • TYROSINE HYDROXYLASE. THE INITIAL STEP IN NOREPINEPHRINE BIOSYNTHESIS. (1787 citations)
  • Fluorometric assay of proteins in the nanogram range (1486 citations)

What are the main themes of his work throughout his whole career to date?

The scientist’s investigation covers issues in Biochemistry, Internal medicine, Endocrinology, Enzyme and Amino acid. Much of his study explores Biochemistry relationship to Molecular biology. His research investigates the connection with Internal medicine and areas like Pharmacology which intersect with concerns in Monoamine oxidase.

His research in Endocrinology intersects with topics in Tyrosine, In vivo and Serotonin. Sidney Udenfriend interconnects Tryptophan, Phenylalanine and Tyrosine hydroxylase in the investigation of issues within Tyrosine. The various areas that Sidney Udenfriend examines in his Amino acid study include Peptide sequence, Chromatography and Peptide.

He most often published in these fields:

  • Biochemistry (58.37%)
  • Internal medicine (22.41%)
  • Endocrinology (22.17%)

What were the highlights of his more recent work (between 1979-2020)?

  • Biochemistry (58.37%)
  • Enkephalin (7.39%)
  • Molecular biology (11.33%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Biochemistry, Enkephalin, Molecular biology, Amino acid and Peptide sequence. His work in Peptide, Membrane protein, Proenkephalin, Enzyme and Complementary DNA is related to Biochemistry. His Enkephalin research includes themes of Adrenal medulla, Opioid peptide, Bovine adrenal, Endorphins and Medulla.

Sidney Udenfriend has begun a study into Adrenal medulla, looking into Endocrinology and Internal medicine. His study looks at the relationship between Molecular biology and fields such as Molecular cloning, as well as how they intersect with chemical problems. His work is dedicated to discovering how Amino acid, Alkaline phosphatase are connected with Isozyme, Homology and Glycosylation and other disciplines.

Between 1979 and 2020, his most popular works were:

  • Molecular cloning establishes proenkephalin as precursor of enkephalin-containing peptides (553 citations)
  • How glycosylphosphatidylinositol-anchored membrane proteins are made. (443 citations)
  • Biochemistry of the enkephalins and enkephalin-containing peptides. (243 citations)

In his most recent research, the most cited papers focused on:

  • Enzyme
  • Biochemistry
  • Amino acid

His main research concerns Biochemistry, Enkephalin, Peptide sequence, Peptide and Amino acid. His Biochemistry study combines topics in areas such as Medulla and Stereochemistry. His Enkephalin research includes elements of Adrenal medulla, Endorphins, Endocrinology and Molecular biology.

His Peptide sequence research focuses on Complementary DNA and how it connects with Proenkephalin, Transporter and Xenopus. In general Amino acid, his work in Alanine is often linked to Glutamate aspartate transporter linking many areas of study. His biological study deals with issues like Signal peptide, which deal with fields such as Enzyme.
