Question

The amino acids which are not synthesized in the
body are called –
(a) non-essential (b) essential
(c) deaminated (d) All of them

Answer 1

(b) Essential Amino Acid

Explanation:

Those  amino acid which cannot synthesised by human body  and take from outside in the form diet is known Essential Amino Acid . Essential amino acid includes  ( i.e,  histidine , valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and phenylalanine) out of 20 amino acid . Essential amino  acid cannot manufacture in our body due to lack of such enzyme which transform biological molecules in essential amino acid molecules .

Answer 2

The amino acids which are not synthesised in the  body are called (b) essential amino acids.

Explanation:

• There are 21 common amino acids present in life forms.
• Some of the amino acids are secreted naturally and other essential amino acids are not secreted naturally.
• These amino acids required food (diet) for the body to supply it. These are named as essential amino acids.
• Out of 21, 9 amino acids come under this category.
• Some of these acids include valine, phenylalanine, tryptophan, threonine, leucine, methionine, lysine, histidine and isoleucine.
• Food that provide essential amino acids (proteins) are good for consumption whereas some food that provide non-essential amino acids (fats and carbohydrate) should not be consumed much.
