<u>Mucins</u> are water-soluble, complex glycoproteins that are secreted by goblet cells.
Explanation:
Goblet cells, named after their goblet-like shape, are usually found in the epithelium of respiratory and intestinal tracts in the body. Their main function is to produce mucus (primarily made up of mucins), a slippery combination of proteins, water and sugars, that serves three main functions:
- The barrier function: By trapping the unwanted/harmful particles that we inhale and preventing them from entering our system.
- The protection function: By keeping the hair-like cilia lubricated and moist to remove the harmful particles.
- The defence function: Mucus is made up of certain enzymes, antibodies and proteins that act as a defence mechanism for the body.
A unique property of mucins is their capability to form gels - sticky and viscous substances that work both as lubricants as well as defensive chemical barriers in the body.

Macromolecules
are a set collection of polymers that composes most of the organic substances
specifically in the organelles of cells. Thus, these organelles use lipids and
proteins in doing cellular activity and keeps them functioning. Observe
nitrogen and carbon, these two entities are called elements that are composed
of atoms. Elements are the basic composition of a substance. Going back,
examples of molecules could be nucleic tides, polypeptides, RNA, protein,
lipids and etc. </span>
