胺基酸的代謝:生合成(biosynthesisofaminoacid)•固氮作用:•大氣中的氮在酵素催化下還原成氨(NH3)的作用，只有少數的原核微生物(prokaryoticmicroorganism)具有固氮作用的能力。•支鏈胺基酸(BCAA:branchedchainaminoacids):包含leucine、isoleucine與valine。在肝臟中大量的NAA與EAA被分解，但EAA中的BCAA卻是例外。

Besides this, some of them play a major role in other functions, such as regulation of protein turnover and signal transduction, transport of nitrogen and carbon across the organs, or neurotransmission. The unique characteristics of amino acids are the presence of a free amino group in the 伪...
An overview of amino acid biosynthesis is given by glucose. Biosynthesis of serine from 3-phosphoglycerate and subsequent conversion of serine into glycine is explained with the diagram. General properties of amino acids are also given in this study. Keywords: Amino acids, building blocks, glucose,...
The products of amino acid breakdown are of two kinds. Ketone bodies—that is, acetoacetate and hydroxybutyrate—are formed from the catabolism of the branched‐chain amino acids, lysine and some aromatic amino acids. Tricarboxylic acid (TCA) cycle intermediates, including pyruvate and glutamate, are...

The aminoshikimate pathway of formation of 3-amino-5-hydroxybenzoic acid (AHBA), the precursor of ansamycin and other antibiotics is reviewed. In this biosynthesis, genes for kanosamine formation have been recruited from other genomes, to provide a nitro
