Summary
High intake of amino acids (AAs) may pose health risks. This study focuses on sulfur amino acids, aiming to characterize risks from excessive AA consumption in humans.
Area of Science:
- Nutritional Biochemistry
- Toxicology
- Human Health
Background:
- Amino acids (AAs) are sometimes consumed at high levels for health benefits, particularly in sports and aging.
- Excessive AA intake may lead to adverse effects, but data on these consequences are limited.
- A series of workshops (AAAW) were established to address risks of high AA intake.
Purpose of the Study:
- To characterize the risks associated with specific high intakes of sulfur amino acids in humans.
- To establish a framework for evaluating the safety of elevated amino acid consumption.
- To synthesize expert knowledge on sulfur amino acid metabolism and toxicology.
Main Methods:
- The fifth Amino Acid Assessment Workshop (AAAW) convened experts in metabolism, nutrition, toxicology, and policy.
- Discussions focused on sulfur amino acids, building upon previous workshops covering general AA aspects and branched-chain AAs.
- The workshop aimed to define a paradigm for risk characterization of specific AA intakes.
Main Results:
- The workshop identified knowledge gaps regarding the adverse effects of excessive sulfur amino acid intake.
- Expert consensus was sought on methodologies for risk assessment of individual amino acids.
- The findings contribute to a broader understanding of amino acid safety at high doses.
Conclusions:
- Further research is needed to fully understand the toxicological profile of excessive sulfur amino acid consumption.
- A systematic approach to risk assessment is crucial for establishing safe intake levels of amino acids.
- This work provides a foundation for future regulatory and health guidance on amino acid supplementation.

01:07Amines: Introduction
Amines are organic derivatives of ammonia. They are formed by replacing one or more ammonia protons with alkyl or aryl groups. Depending upon the number of organyl groups bonded to nitrogen, amines are classified as primary, secondary, or tertiary. Primary amines have one organyl group attached to the nitrogen atom, while secondary and tertiary amines have two and three organyl groups attached to the nitrogen atom, respectively.
01:29Amino Acid Biosynthetic Pathways
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which provide...
03:42Amino acids
Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...
01:15Mass Spectrometry of Amines
In mass spectroscopy, amines undergo fragmentation to give parent ions with odd molecule weights. This observed mass spectrum follows the nitrogen rule; a molecule with an odd number of nitrogen atoms produces a molecular ion with an odd molecular weight. Amines undergo fragmentation through α cleavage, producing nitrogen-containing cations—iminium ions—and alkyl radicals. Mass spectra of aromatic and cyclic aliphatic amines exhibit strong molecular ion peaks, but acyclic aliphatic amines show...
01:13Five-Membered Heterocyclic Aromatic Compounds: Overview
Heterocyclic aromatic compounds are cyclic compounds that are aromatic and have one or more heteroatoms—atoms other than carbon, in the ring. Depending upon the number of atoms present in the ring, they can be either five or six-membered. Examples of five-membered heterocyclic aromatic compounds include pyrrole, furan, thiophene, and imidazole. Pyrrole consists of one nitrogen atom having one lone pair of electrons. Furan and thiophene have one oxygen and one sulfur heteroatom, respectively.
01:33Peptide Identification Using Tandem Mass Spectrometry
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...
