Question

9. Which amino acid is INCORRECTLY matched to its side-chain? (A) Lysine : &-amino-aliphatic hydrocarbon chain (B) Glutamic acid : ß-carboxylate-aliphatic hydrocarbon chain (C) Tyrosine: aromatic imidazole (D) Methionine : y-methylmercapto-aliphatic hydrocarbon chain​

Answer 1

Explanation:

for four bodies a b c and d. in each case state what information do you get from the acceleration (Zero, negative or positive)

Answer 2

Answer:

Tyrosine amino acid is incorrectly matched with its given side chain.

Therefore the option (C) is correct.

Explanation:

• Amino acids are the compound which contains both an amino group and an acidic group in their molecules.

• In amino acid, the basic group (-NH₂) and acidic group (-COOH) are bonded to a common carbon. The same carbon bonded to one hydrogen as well as one side chain. Due to different nature of side chain, we have around 20 different type of natural amino acids.
• We can represent amino acid as :   $\\ H_{2}N-C(R)(H)-COOH$

        where R is the side chain.

Among the given amino acids, the side chain attached to Tyrosine is 4-hydroxyphenyl instead of aromatic imidazole.

Therefore Tyrosine amino acid is incorrectly matched with its side chain.
