7 0

Answer:

The correct answer is D.

Explanation:

Amino acids can be classified <u>depending on the side chain structure</u> in

  1. acidic
  2. basic
  3. neutral
  4. aliphatic
  5. aromatic
  6. sulfur containing amino acids.  

Aspargine is a <em>neutral amino acid</em> that has a key role in <u>glycoproteins biosynthesis.</u> Aspargine helps the body to resist fatigue and contributes to a smooth functioning of the liver.

<h3>What are elements?</h3>

Elements are pure substances which are composed of similar atoms.

Elements are defined as substances which cannot be split into simpler substances by an ordinary chemical process.

Elements have different physical and chemical properties and can be classified into:

  • metals
  • semi-metals
  • non-metals

In conclusion, the physical and chemical properties of the elements vary from metals to non-metals.

ara h 6 complements ara h 2 as an important marker for ige reactivity to peanut audrey e. koid,† martin d. chapman,†
frez [133]

Purified Ara h 6 will be helpful for research into the immunological mechanisms underlying peanut allergy, including molecular and cellular studies, diagnostic IgE antibody testing, and clinical trials.

1.4% of children and 0.6% of adults in the United States suffer from the food allergy peanut. Approximately 1.8% of youngsters in the UK are allergic to peanuts. Food allergies to milk, eggs, and wheat are often outgrown by children, while allergies to peanuts are more persistent and frequently last into adulthood. As little as 0.4 g of peanut is required to cause milder allergic reactions like rashes, angioedema, and gastrointestinal problems. However, peanut is also one of the leading causes of severe, sometimes fatal anaphylactic reactions.
