(a) Amino acids are the building blocks of protein in our body. Our body can synthesise certain amino acids, but others, called essential amino acids, must come from protein-containing foods in our diet. These essential amino acids are histidine, isoleucine, leucine, lysine,methionine, phenylala...
Phenols and flavonoids are also synthesized from aromatic amino acids such as tryptophan, tyrosine, and phenylalanine. Amino acids are important in human nutrition. Plants can synthesize all amino acids, but animals need some amino acids (called essential amino acids) from plants or other animals ...
Amino acids are also used in medicine. Amino acid infusions prepared from crystalline amino acids are used as nutritional supplements for patients before and after surgery. Some amino acids and their analogues are used for treatment of major diseases. α-Methyl-DOPA is an effective antidepressant. ...
of the protein. Amino acids are linked together in varying sequences to form a vast variety of proteins. Amino acids are also important in many other biological molecules, and due to this central role in biochemistry, they are very important in nutrition. ...
Any of a large number of compounds that are found in living cells, contain carbon, oxygen, hydrogen, and nitrogen, and join together to form proteins. ♦ About 20 amino acids are needed by animal cells to produce proteins, but only about half, callednonessential amino acids, can be produ...

Amino acids are mainly removed in three ways, namely oxidative deamination, deamination, and combined deamination. Metabolism of four - keto acids 1. amino acid into amino acid 2. change to sugar or fat 3. oxidation energy supply Five. Metabolism of ammonia 1. sources and routes of blood amm...
aThe altered amino acidswere highly conserved evolutionarily and the mutations were consistently associated with a significantly decreased transcriptional activity. 修改过的氨基acidswere高度被保存的evolutionarily和变化一贯地同significantly减少的transcriptional活动联系在一起。[translate]...
Besides their role as protein constituents, amino acids are also involved in a plethora of cellular reactions and therefore they influence a number of physiological processes such as plant growth and development, intracellular pH control, generation of metabolic energy or redox power, and resistance ...
