A protein ' $X$ ' with molecular weight of $70,000 u$, on hydrolysis gives amino acids One of these amino acid is
A protein ' $X$ ' with molecular weight of $70,000 u$, on hydrolysis gives amino acids One of these amino acid is
Show Hint
The Correct Option is B
Approach Solution - 1
Only in option (2) a-Amino acid is given all the other options are not a-Amino acids.
Approach Solution -2
Step 1: The given molecule has the structure of an amino acid, which is identified by the presence of both a carboxyl group (-COOH) and an amine group (-NH₂).
Step 2: The structure shown in the second image matches the chemical structure of Leucine, which is a branched-chain amino acid (BCAA). The chemical formula of Leucine is C₆H₁₃NO₂, and its side chain contains an isopropyl group (–CH₃) attached to a central carbon.
Step 3: The molecular weight of Leucine is approximately 131.17 g/mol, and it is one of the amino acids that could be released upon hydrolysis of a protein like 'X' with the molecular weight of 70,000u.
Thus, the correct answer is option (B) Leucine.

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
