4 amino acids

Classification of Amino Acids Base on Polarity - Amino acids are classified into different ways based on polarity, structure, nutritional requirement, metabolic fate, etc. Generally used classification is based on polarity. Based on polarity amino h..

Proteins are the polymers of amino acids. Therefore, amino acids form the raw material for protein synthesis. The proteins found in living organisms need about 20 amino acids as building blocks or monomers. These are available in the cyto..

Amino acids are compounds containing carbon, hydrogen, oxygen and nitrogen. They serve mainly as monomers (building blocks) of proteins. An amino acid is represented by a general empirical formula R.CH.NH 2 . COOH. Each amino acid has at l..

Excess amino acids or proteins in higher animals are broken down into ammonia which are converted into less toxic substances like urea and uric acid in the liver. But in lower animals like molluscs and echinoderms the excess amino acid gets removed..

Amino acids are the building blocks of proteins. There are 300 amino acids that occur in nature. Among these only 20 are known as standard amino acids that commonly occur in proteins. Amino acids contain two functional ..

The amino acids that are to be supplied through diet are called as essential amino acids. They cannot be produced by the body. The essential amino acids are arginine, valine, histidine, isoleucine, leucine, lysine, methionine, phenylalani..

Amino acids are synthesised by two main processes: 1) Reductive animation In this process, ammonia reacts with a -ketoglutaric acid to form glutamic acid..

are those that are not synthesized by the body and are needed in the diet. Methionine, threonine, tryptophan, valine, isoleucine, leucine and phenylalanine are the essential amino acids..

All amino acids have trivial names. IUPAC names which even if not cumbersome are not used. For e.g., H 2 N CH 2 COOH is better known as glycine rather then a -amino acetic acid or 2-amino ethanoic acid..
