they are essential for the synthesis of purines.
|
|
|
they are essential for nitrogen metabolism.
|
|
|
our bodies need them for protein synthesis.
|
|
|
our bodies cannot synthesize them and therefore they need to be present in our diet.

Detailed explanation-1: -Our body can not synthesize some amino acids. These amino acids are included in essential amino acids. In total there are 20 amino acids which our body can not synthesize, so these must be present in our diet.
Detailed explanation-2: -Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Detailed explanation-3: -These 20 amino acids combine in different ways to make proteins in your body. Your body makes hundreds of amino acids, but it can’t make nine of the amino acids you need. These are called essential amino acids. You must get them from the food you eat.
Detailed explanation-4: -It is well known that proteins are built up from an alphabet of 20 different amino acid types. These suffice to enable the protein to fold into its operative form relevant to its required functional roles.
