Proteins and Amino Acids
Proteins, from the Greek proteios, meaning first, are a class of organic compounds which are present in and vital to every living cell. In the form of skin, hair, callus, cartilage, muscles, tendons and ligaments, proteins hold together, protect, and provide structure to the body of a multi-celled organism. In the form of enzymes, hormones, antibodies, and globulins, they catalyze, regulate, an...
متن کاملHIGH-PERFORMANCE LIQUID CHROMATOGRAPHIC ANALYSIS OF SULFUR MUSTARD REACTION WITH AMINO ACIDS AND PROTEINS
The interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. Rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. At different time intervals, plasma and urine samples were collected. The binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-i...
متن کاملSolubility of amino acids, sugars, and proteins*
The importance of biomolecules is well recognized nowadays, owing to their application in many industrial processes, particularly in the food, pharmaceutical, and cosmetic industries. Amino acids, carbohydrates, and proteins are the three types of biomolecules considered in this review. Solubilities of several amino acids and sugars have been measured in water and, more recently, in mixed solve...
متن کاملChemistry for Physicians: Amino Acids and Proteins
In the human organism, proteins undertake multiple and vital functions. Structural proteins are found in each and every cellular compartment. Intracellularly, motor proteins power the energy-dependent transportation of vesicles. Signal proteins receive and transmit information. Transport and storage proteins bind, for example, oxygen, and carry it to a location where it is needed. Of equally gr...
متن کاملMass Spectrometry of Amino Acids and Proteins
Likemostmatter (with the exception of, say, neutron stars), proteins and peptides are mostly made of nothing – an ephemeral cloud of electrons with very little mass surrounding tiny and very dense atomic nuclei that contain nearly all of themass (i.e., peptides and proteins aremade of atoms). Atoms havemass and the unit ofmass that is most convenient to use is called the atomic mass unit (abbre...
