Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Hormones can be steroids, peptides or amino acid derivatives.
Step 2: Classify
Thyroxine is an iodinated derivative of tyrosine. Oxytocin and parathormone are peptide or protein hormones, and estrogen is a steroid.
Final Answer:
Thyroxine is a modified amino acid. \[ \boxed{\text{(A) }\text{Thyroxine}} \]
