the 20 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 i..

Amino Acids - 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 ..

Structures of Amino Acids - 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 protein..

Amino acids are compounds containing carbon, hydrogen, oxygen and nitrogen. They serve mainly as monomers (building blocks) of protein..

These have two carboxyl groups and one amino group. The free carboxyl group is acidic in nature. For example, aspartic acid and glutamic acid..

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

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..

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..
