- ) accepts a proton and gets converted to carboxyl substituent (- COOH) while in basic solution the ammonium substituent (+NH 3 ) changes to amino group (-NH 2 ) by losing a proton. In acidic solution, an amino acid exists as a positive ion and migr..

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 ..

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

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 proteins. Am..

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..

Nomenclature of 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 ..
