What is the Most Abundant Protein in the Human Body

Question

What is the most abundant protein in the human body?  
A) Polysaccharides
B) Elastin
C) Collagen
D) Amino acid
E) Triglycerides

Accepted Answer

Collagen is the most abundant protein in the human body, accounting for about 30% of total protein mass. It is a major component of connective tissues, such as tendons, ligaments, skin, and bones. Polysaccharides, elastin, and triglycerides are not proteins, while amino acids are the building blocks of proteins rather than a single most abundant protein.
