<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.

Leaching is the process where dissolved nutrients in the
soil profile moves downward with percolating water. It is the loss of
water-soluble plant nutrients from the soil. The nutrients that seep through
the rooting zone may be recycled if roots grow deeper.
