Question

Which of the following essential amino acid is present in wheat?

• A. glycine
• B. alanine
• C. lysine `
• D. serine

Answer 1

The correct option is C lysine `

Lysine is the essential amino acid present in wheat. Wheat is higher in crude protein but, more importantly, is higher in lysine.

Lysine is an important essential amino acid which forms the building blocks of protein. It is especially important because it is the first limiting amino acid in a grain-soyabean meal diet. This means that if a diet is formulated to supply the correct amount of lysine, then generally, the levels of the other essential amino acids will be adequate.

Therefore, lysine content is an important consideration when comparing cereal grains. Glycine, alanine and serine are non-essential amino acids which are synthesized within the body.
