Recent questions
What are biomolecules?
Biomolecules are naturally occurring organic compounds essential for plant and animal survival. They play crucial roles in various biological processes and are the building blocks of life.
How are carbohydrates classified?
Carbohydrates are classified into mono saccharides, oligo saccharides, and poly saccharides based on their behavior with water. This classification helps in understanding their structure, function, and importance in biological systems.
What is the structure of glucose?
Glucose has a molecular formula of C6H12O6, containing six carbon atoms and an aldehyde functional group. It reacts with various reagents to confirm the presence of the aldehyde group and undergoes different reactions to form various compounds.
How is glucose represented in Fischer projection?
Glucose is represented in Fischer projection based on the position of hydrogen and oxygen on the first carbon atom. It can exist in alpha or beta form, and the structure is crucial for identifying functional groups and linkages in carbohydrates.
What is the importance of proteins in biological systems?
Proteins play essential roles in catalysis, transport, and structure within living organisms. Their primary, secondary, and tertiary structures determine their functions, and denaturation can occur due to external factors like pH or temperature changes.
