What are essential and non-essential amino acid? Give two examples of each type.


Essential amino acids : Those amino acids which are not synthesised by our body are called essential amino acids. They must be part of our diet. Their deficiency leads to diseases such as Kwashiorkor (water balance in the body is disturbed). Valine, leucine, isoleucine, phenyl alanine, methionine, tryptophan, threonine, lyslne, arginine and histadine are ten essential amino acids.

Non-essential amino acids: The amino acids, which can be synthesised in the body, are known as non-essential amino acid. They are also called dispersable amino acids e.g., glycine, alanine, seriqe, cysteine, glutamine, tyrosine, proline, aspartic acid, asparagine, glutamic acid.
