amino acids

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 ..

There are two types of amino acids as per the nutritional requirement. They are classified into essential and non-essential amino acids..

Classification of Amino Acids Based on Nutrition - According to the classification based on nutrition, they are divided into two types: They are: Essential amino acids and Non-essential amino acids..

It is the step in which each of the participating amino acid reacts with ATP to form amino acid AMP complex and pyrophosphate. The reaction is catalyzed by a specific amino acid activating enzyme called aminoacyl-tRNA synthetase in the pr..

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..

Peptide Bond Formation - When two amino acids combine with each other, the amino group of one amino acid combines with carboxyl group of other amino acid. This leads to peptide bond formation. The combination of the amino..
