Question

Isoleucine, leucine, and lysine are three examples of amino acids that the body can not make in sufficient quantity. How are these compounds classified

Answer 1

Answer:

Leucine, isoleucine and lysine are classified as essential amino acids.

Explanation:

Amino acids are the important biomolecules in which an alpha-carbon is attached to a side chain R, two functional groups and one hydrogen.

The two functional groups are: amine group (-NH₂) and carboxyl group (-COOH).

There are total 21 amino acids in a human body. They can be divided into two types: Essential amino acids and Nonessential amino acids

Essential amino acids are the 9 amino acids that can not be produced by the human body and thus has to be taken through diet.

Example: leucine, isoleucine, lysine.

Therefore, leucine, isoleucine and lysine are classified as essential amino acids.

Answer 2

Answer:

Isoleucine, leucine and lysine are essential amino acids.

Explanation:

The amino acids are classified based on different criteria like

a) Polarity

b) acidc, basic or neutral behavior

c) aromatic or non aromatic

One important classification is that amino acids can be "essential" or "non essential".

Essential amino acids are those which cannot be made by our body and thus are required in our diet.

Non essential amino acids are those which our body can synthesize. So are not required in our diet.

So  Isoleucine, leucine and lysine are essential amino acids.
