Amino acids can be boardly classified into three classes i.e., acidic, alkaline and neutral amino acids depending on the number of group and group.
Acidic amino acids : Those -amino acids such as aspartic acid, asparagine and glutamic acid which contain two groups and one group are called acidic amino acids.
Alkaline or Basic amino acids : Those -amino acids such as lysine, arginine and histidine which contain two groups and one group, are called basic amino acids.
Neutral amino acids : Those -amino acids such as glycine, alanine, valine etc. which contain one and one group, are called netural amino acids.
Essential and non-essential amino acids :
Essential amino acids : Amino acids which the body cannot synthesize are called essential amino acids.
Example : Valine, leucine etc. Therefore they must be supplied in diet.
Non-essential amino acids : Amino acids which the body can synthesize are called non-essential amino acids. Therefore, they may or may not be present in diet.
Example : Glycine, alanine etc.
