Front

What are lipids?

Back

Lipids are a class of macromolecules made of glycerol and fatty acids, which are hydrophobic and serve various functions including energy storage and forming cell membranes.

Front

What are proteins made of?

Back

Proteins are macromolecules made of monomers called amino acids, which are linked together by peptide bonds.

Front

What is a negative control in a protein test?

Back

A negative control is a sample that does not contain the substance being tested for, used to validate the test results. For protein tests, RO water and Biuret solution serve as a negative control.

Front

Identify the macromolecule associated with the structure of cell membranes.

Back

Lipids are the macromolecules associated with the structure of cell membranes, primarily phospholipids.

Front

What is the purpose of the Biuret test?

Back

The Biuret test is used to detect the presence of proteins in a sample by changing color in the presence of peptide bonds.

Front

What are carbohydrates?

Back

Carbohydrates are macromolecules made of sugar monomers, serving as a primary energy source and structural components in cells.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are macromolecules made of nucleotide monomers that store and transmit genetic information.

Front

What is the role of amino acids in proteins?

Back

Amino acids are the building blocks of proteins, determining the protein's structure and function based on their sequence.

Front

What is the difference between polypeptides and proteins?

Back

Polypeptides are chains of amino acids, while proteins are functional molecules that may consist of one or more polypeptide chains folded into a specific structure.

Front

What is the significance of the Benedict's test?

Back

The Benedict's test is used to detect reducing sugars, such as glucose, by changing color in the presence of these sugars.
