Today, we will dive into carbohydrates. Can anyone tell me what carbohydrates are?

Student 1
Student 1

Are they sugars?

Teacher
Teacher

Correct! Carbohydrates are indeed sugars and can be classified into three main groups: monosaccharides, oligosaccharides, and polysaccharides. Who can explain the difference?

Student 2
Student 2

Monosaccharides are single sugar units like glucose, and polysaccharides are long chains of sugar units like starch.

Teacher
Teacher

Exactly! A helpful acronym to remember the classifications is MOP: Monosaccharides, Oligosaccharides, and Polysaccharides. Can anyone give examples of each type?

Student 3
Student 3

An example of oligosaccharides is sucrose, right?

Student 4
Student 4

And polysaccharides include starch and cellulose!

Teacher
Teacher

Great job! Remember, polysaccharides serve as energy storage, while monosaccharides are the primary source of energy. Let's summarize: MOP represents the classification of carbohydrates into Monosaccharides, Oligosaccharides, and Polysaccharides.

Let's shift gears to proteins. Can anyone tell me what proteins are made of?

Student 1
Student 1

Amino acids!

Teacher
Teacher

Correct! Proteins are polymers of amino acids linked by peptide bonds. There are 20 amino acids we commonly discuss. How are these amino acids classified?

Student 2
Student 2

They can be essential or non-essential, right?

Teacher
Teacher

Exactly! Essential amino acids must be obtained through diet, while non-essential amino acids can be synthesized by the body. Remember the mnemonic 'Remember for Meals' - RFM helps recall the essential amino acids. What are some functions of proteins?

Student 3
Student 3

They can build structures like muscles and enzymes!

Teacher
Teacher

Absolutely! Both structural and functional roles are vital. In summary, proteins are vital biomolecules made of amino acids, distinguishing between essential and non-essential types.

Teacher

Now, who can tell me what vitamins are?

Student 4
Student 4

They are organic compounds needed in small amounts!

Teacher
Teacher

Correct! Vitamins are essential for our diet, classified into water-soluble and fat-soluble. Who can name some vitamins from each category?

Student 1
Student 1

Vitamin C is water-soluble and Vitamin A is fat-soluble!

Student 2
Student 2

What diseases are caused by deficiencies in these vitamins?

Teacher
Teacher

Great question! Deficiency of Vitamin C leads to scurvy while Vitamin A deficiency can cause night blindness. An easy way to remember the water-soluble vitamins is ‘B and C’! Let's recap: Vitamins are crucial for health, classified into water-soluble and fat-soluble.

Nucleic Acids

Teacher

Let’s discuss nucleic acids next. Can anyone tell me the two main types?

Student 3
Student 3

DNA and RNA!

Teacher
Teacher

Correct! DNA is the genetic blueprint of life, while RNA plays a role in protein synthesis. What is a key structural difference between them?

Student 1
Student 1

DNA has deoxyribose and RNA has ribose as sugars.

Student 2
Student 2

DNA is double-stranded, while RNA is single-stranded!

Teacher
Teacher

Exactly! To remember this, think of 'DNA is Double' and 'RNA is a Rib'. These differences are critical for their functions in heredity and protein synthesis.
