Lipids and Nucleic Acids

Front

What are phospholipids?

Back

Phospholipids are molecules that make up the basic structure of cell membranes, consisting of a hydrophilic (water-attracting) 'head' and two hydrophobic (water-repelling) 'tails'.

Front

Why are lipids important for energy storage?

Back

Lipids are efficient for energy storage because they are long chains of carbon and hydrogen, which store more energy per gram than carbohydrates or proteins.

Front

What is the pentose sugar found in DNA?

Back

The pentose sugar found in DNA is deoxyribose.

Front

What is a nucleotide?

Back

A nucleotide is the monomer unit of nucleic acids, consisting of a nitrogenous base, a pentose sugar, and a phosphate group.

Front

What distinguishes unsaturated fats from saturated fats?

Back

Unsaturated fats contain one or more double bonds in their fatty acid chains, while saturated fats have no double bonds.

Front

What role do lipids play in the body?

Back

Lipids serve various roles including energy storage, insulation, and forming cell membranes.

Front

What are the two main types of nucleic acids?

Back

The two main types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

Front

What is the function of RNA?

Back

RNA plays a crucial role in protein synthesis and can also have roles in catalyzing biochemical reactions.

Front

What is the structure of a triglyceride?

Back

A triglyceride is composed of one glycerol molecule bonded to three fatty acid chains.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
