What are carbohydrates?

Back

Carbohydrates are organic molecules made up of carbon, hydrogen, and oxygen, primarily serving as a source of energy and structural components in living organisms.

Front

What are lipids?

Back

Lipids are organic molecules that are hydrophobic and include fats, oils, and phospholipids, used for long-term energy storage and forming cell membranes.

Front

What are proteins?

Back

Proteins are large, complex molecules made up of amino acids, essential for the structure, function, and regulation of the body's tissues and organs.

Front

What are nucleic acids?

Back

Nucleic acids are organic molecules that store and transmit genetic information, including DNA and RNA.

Front

What are monosaccharides?

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What are disaccharides?

Back

Disaccharides are carbohydrates formed by the combination of two monosaccharides, such as sucrose (glucose + fructose) and lactose (glucose + galactose).

Front

What are polysaccharides?

Back

Polysaccharides are complex carbohydrates made up of long chains of monosaccharide units, such as starch, glycogen, and cellulose.

Front

What is the primary function of carbohydrates in the body?

Back

The primary function of carbohydrates is to provide energy for the body, especially for the brain and muscles during physical activity.

Front

How do lipids contribute to cell membranes?

Back

Lipids, particularly phospholipids, form the structural foundation of cell membranes, creating a barrier that separates the interior of the cell from the external environment.

Front

What role do proteins play in biological processes?

Back

Proteins serve various roles, including acting as enzymes to catalyze biochemical reactions, providing structural support, and facilitating communication between cells.
