Exp: A Phospholipids are amphipathic carrying both hydrophilic polar and Hydrophobic non polar groups. - The hydrocarbon chains of the two fatty acids function as form hydrophobic non polar tails of the phospholipids molecules. The phosphate and additional group (nitrogenous or non nitrogenous) behave as hydrophilic polar group of the molecule.

Lipids are insoluble in water because lipid molecules are : -
1 Hydrophilic
2 Hydrophobic
3 Neutral
4 Zwitter ions
Explanation:
Exp: B Lipids are organic compounds which are non polar molecules. They are soluble only in non polar solvents and insoluble in polar solvents like water. Lipid lack charged groups, the water molecules have nothing to stick and don't mix with them.

A phosphoglyceride is always made up of :
1 a saturated or unsaturated fatty acid is esterified to a phosphate group which is also attached to a glycerol molecule
2 only saturated fatty acid is esterified to a glycerol molecule to which a phosphate group is also attached
3 only a unsaturated fatty acid is esterified to a glycerol molecule to which a phosphate group is also attached
4 a saturated or unsaturated fatty acid is esterified to a glycerol molecule to which a phosphate group is also attached
Explanation:
Exp: D Phosphoglyceride is made of a saturated or unsaturated fatty acid esterified to a glycerol molecule. They are also called as glycerophospholipids. Biological membranes usually involve two layers of phospholipids with their tails pointing inward, this arrangement is called a phospholipid bilayer.

One of the following substances is at its lowest level in fish food:
1 actin
2 myosin
3 cholesterol
4 tissue fluid
Explanation:
Exp: C Cholesterol is present in very low level in the fish food. It is a sterol that is found in very small amounts in fish flesh.
