Alanine (symbol Ala or A), [4] or α-alanine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a methyl group side chain. Consequently it is classified as a nonpolar, aliphatic α-amino acid.
Anacleto del Rosario y Sales (July 13, 1860, Santa Cruz, Manila – May 2, 1895) was a leading chemist in the Philippines during the Spanish era in Philippine history. Regarded as the "Father of Philippine Science and Laboratory", del Rosario invented the formula for producing a pure kind of alcohol from tuba in a nipa palm.
β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine). The IUPAC name for β-alanine is 3-aminopropanoic acid.
The Cahill cycle, also known as the alanine cycle or glucose-alanine cycle, [1] is the series of reactions in which amino groups and carbons from muscle are transported to the liver. [2] It is quite similar to the Cori cycle in the cycling of nutrients between skeletal muscle and the liver. [ 1 ]
Antiquarian science books are original historical works (e.g., books or technical papers) concerning science, mathematics and sometimes engineering.These books are important primary references for the study of the history of science and technology, they can provide valuable insights into the historical development of the various fields of scientific inquiry (History of science, History of ...
The economic history of the Philippines is shaped by its colonial past, evolving governance, and integration into the global economy. Prior to Spanish colonization in the 16th century, the islands had a flourishing economy centered around agriculture, fisheries, and trade with neighboring countries like China, Japan, and Southeast Asia.
Santa Rosa Science and Technology High School founded Science, Technology and Engineering (STE) Curriculum with STEM (Science, Technology, Engineering and Mathematics) Program. It is focused on pure science and its applications to industry using the latest technologies. Computer rooms are to be linked to the internet, including multi-media ...
An obvious synthesis route to α-alaninediacetic acid is from racemic α-DL-alanine, which provides racemic α-ADA by double cyanomethylation with methanal and hydrogen cyanide, hydrolysis of the intermediately formed diacetonitrile to the trisodium salt and subsequent acidification with mineral acids in a 97.4% overall yield.
