Classify phosphoglycerides and sphingomyelins as hydrolyzable or non-hydrolyzable lipids and explain your reasoning.

Phosphoglycerides are non-hydrolyzable, while sphingomyelins are hydrolyzable due to their backbone structure.

Phosphoglycerides and sphingomyelins are hydrolyzable because they contain ester bonds that can be broken down by hydrolysis.

Both phosphoglycerides and sphingomyelins are non-hydrolyzable because they do not contain ester bonds.

Phosphoglycerides are hydrolyzable because of their amide bonds, while sphingomyelins are not.
