Question

Which of the following essential amino acids is present in wheat?
A.Glycine
B.Alanine
C.Lysine
D.Serine

Answer 1

Hint: In this question we are asked about the essential amino acid present in wheat. Essential amino acids are the one which are not formed by our body and we have to take these amino acids from an external source.

Complete step by step solution:
Amino acids are of two type’s essential and non-essential amino acids. Non-essential amino acids are formed by our body and essential amino acids are not formed in the body.
The first option is glycine. Glycine is a non-essential amino acid. So this will not be the answer.
The next option is alanine. This is also a non-essential amino acid.
Coming to the next option we have lysine. Lysine is not formed in our body hence it is an essential amino acid. Also lysine is present in wheat. Humans consume wheat to reduce the chances of deficiency of lysine in the body. So this can be the answer, but we will check the next option also.
The fourth option is serine. Serine is also a non-essential amino acid. So this will not be the answer.

So, the correct option is C.

Additional information:
Wheat is a grass widely cultivated for its seed, a cereal grain which is a worldwide staple food. The many species of wheat together make up the genus Triticum; the most widely grown is common wheat. The scientific name of wheat is Triticum aestivum. There is also a variety of wheat which is lysine rich. This variety is known as Atlas-66

Note: Amino acids are organic compounds that contain amine (\[-N{{H}_{2}}\]) and carboxyl ($-COOH$) functional groups, along with a side chain (R group) specific to each amino acid. The key elements of an amino acid are carbon ($C$), hydrogen ($H$), oxygen ($O$), and nitrogen ($N$), although other elements are found in the side chains of certain amino acids.
