Which class of molecules is the most antigenic?
polysaccharides
lipids
proteins
carbohydrates

Proteins

Explanation:

Proteins are known to be the most antigenic. Antigenicity describes the ability of the foreign materials to bind or interact with B-cell receptors or T-cell receptors.

The T-cell receptor recognizes the linear amino acid chain or sequence which is known as epitope.

They are usually long chains or amino acids or proteins. Some times polysaccharides can also show antigenicity. But they have less antigenicity.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
