What is dehydration synthesis?

Back

Dehydration synthesis is the process of forming a bond between monomers by removing a water molecule.

Front

Why is water considered a polar molecule?

Back

Water is considered polar because it has polar covalent bonds, resulting in a partial positive charge on one end and a partial negative charge on the other.

Front

What is hydrogen bonding in water?

Back

Hydrogen bonding in water refers to the attraction between the hydrogen atom of one water molecule and the oxygen atom of another, leading to properties like cohesion and adhesion.

Front

What are the components of a protein monomer?

Back

The components of a protein monomer (amino acid) include an amine group, a carboxyl group, and an R group (side chain).

Front

What is the role of the carboxyl group in peptide bond formation?

Back

The carboxyl group of one amino acid reacts with the amino group of another amino acid to form a peptide bond.

Front

What is hydrolysis?

Back

Hydrolysis is the process of breaking down a compound by adding water, often used to break down polymers into monomers.

Front

What is cohesion in water?

Back

Cohesion is the property of water that allows molecules to stick to each other, contributing to surface tension.

Front

What is adhesion in water?

Back

Adhesion is the property of water that allows it to stick to other substances, which is important for processes like capillary action.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of a liquid that makes it behave as if it has an elastic 'skin'.

Front

What is the significance of the R group in amino acids?

Back

The R group (side chain) determines the specific properties and functions of each amino acid, influencing protein structure and function.
