Macromolecules Unit 1

Front

What are macromolecules?

Back

Large, complex molecules that are essential for life, including proteins, lipids, carbohydrates, and nucleic acids.

Front

What is the primary function of proteins?

Back

Proteins serve as building blocks for tissues, act as enzymes, and play roles in immune response and signaling.

Front

What is denaturation in proteins?

Back

Denaturation is the process where proteins lose their structure and function due to external stress, such as heat or pH changes.

Front

What are carbohydrates?

Back

Organic compounds made of carbon, hydrogen, and oxygen, typically in a 1:2:1 ratio, serving as a primary energy source.

Front

What are lipids?

Back

Hydrophobic organic molecules, including fats, oils, and waxes, that store energy and make up cell membranes.

Front

Why are lipids insoluble in water?

Back

Lipids are non-polar molecules, which means they do not interact well with polar molecules like water.

Front

What is the structure of a fatty acid?

Back

A fatty acid consists of a long hydrocarbon chain with a carboxyl group (-COOH) at one end.

Front

What is a monosaccharide?

Back

The simplest form of carbohydrates, consisting of a single sugar unit, such as glucose or fructose.

Front

What is the role of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

What is a polymer?

Back

A large molecule composed of repeating structural units (monomers) connected by covalent bonds.
