Which one is false?

Options

A. Fatty acids may be unsaturated (with one or more C=C bonds) or a saturated (without double bonds)
B. Fatty acid(s) may be esterified with glycerol forming monoglyceride, diglyceride and then triglyceride
C. Sometimes especially neural tissues have lipid very much simple structures
D. Fats and oils are triglycerides

Answer

To determine which statement is false among the given options, we will analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement:** Fatty acids may be unsaturated with one or more double carbon bonds or saturated without double bonds.

**Analysis:**
- Fatty acids are classified into two types: saturated and unsaturated.
- Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds.
- This statement is true.

### Step 2: Analyze the Second Statement
**Statement:** Fatty acids may be esterified with glycerol forming monoglyceride and then triglyceride.

**Analysis:**
- Esterification occurs when a fatty acid reacts with an alcohol (like glycerol) to form an ester bond.
- One fatty acid and glycerol form a monoglyceride, while three fatty acids and one glycerol form a triglyceride.
- This statement is also true.

### Step 3: Analyze the Third Statement
**Statement:** Neural tissue has very simple structures.

**Analysis:**
- Neural tissue is primarily composed of neurons and glial cells, which have complex structures and functions.
- Neurons are specialized for conducting nerve impulses, and they are not simple in structure.
- This statement is false.

### Conclusion
The false statement among the given options is the third one: "Neural tissue has very simple structures."
