Answer:
Cholesterol, steroids and phospholipids are examples of the Y-macromolecule, which corresponds to lipids.
Explanation:
Lipids are organic macromolecules made up of fatty acids with multiple functions in the body, such as constituting cell membranes, components of substances such as hormones or energy reserves.
Macromolecule Y is definitely a lipid, formed by fatty acids, from which cholesterol, steroids and phospholipids are derived.
- Cholesterol is a lipid that can be found in cells, forming part of the plasma membrane, in the blood in the form of lipoproteins or in the body's tissues.
- Steroids are unsaponifiable lipids, from which hormones and other compounds are derived. They are formed by a base molecule of cyclopentane-perhydro-phenanthrene.
- Phospholipids are formed by one alcohol and two fatty acids, being the main constituents of the cell membrane.
The other macromolecules fulfill various functions in the body, but are not part of the composition of cholesterol, steroids or phospholipids.
