Amino acid is to protein as
A. fat is to lipid
B. DNA is to RNA
C. sugar is to fat
D. simple sugar is to cellulose
I think it is A..?
You are correct! Amino acid is to protein as fat is to lipid.
To understand this relationship, let's break it down:
Amino acids are the building blocks of proteins. They are organic compounds that contain an amino group (-NH2) and a carboxyl group (-COOH). When amino acids combine together through a process called protein synthesis, they form proteins.
Similarly, fats are organic compounds composed of glycerol and fatty acids. They are the building blocks of lipids. When glycerol combines with fatty acids through a process called esterification, they form lipids or triglycerides.
Therefore, the analogy compares the relationship between amino acids and proteins to the relationship between fats and lipids. The correct answer is A. fat is to lipid.
