Biology Chapter: Nucleic Acids and Amino Acids

Amino Acids and Their Unique Properties

• Each amino acid's unique properties are determined by its side group (R group).
• Essential structure includes an amino group, carboxyl group, and a variable side chain.

Nucleic Acids

• Two types of nucleic acids: DNA and RNA.
• Nucleotides are the building blocks that form nucleic acids.

Relationship of Molecules to Nucleic Acids

• Nucleotides are closely related to nucleic acids, serving as their fundamental units.

Function of DNA

• DNA stores hereditary information vital for genetic inheritance.

Structure of DNA

• Two strands of DNA are held together by hydrogen bonds, ensuring the stability of the double helix structure.

Components of Nucleotides

• A DNA nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.
• It does not contain three phosphate groups.

Energy Storage in ATP

• ATP (adenosine triphosphate) stores energy in the bonds between phosphate groups.

Mass Conservation in Chemical Reactions

• When paper burns, the mass of the resulting carbon dioxide and water vapor is equal to the mass of the original paper and oxygen, adhering to the law of conservation of mass.

Plant Energy Storage

• Plants store glucose as starch, allowing for energy reserve management.

Carbohydrates

• Sucrose is identified as a carbohydrate, with other options such as wax and steroids being incorrect.

Characteristics of Lipids

• Lipids are primarily used by the body for energy storage and are insoluble in water.
• They consist of long chains of carbon and hydrogen.

Exclusions in Lipid Examples

• Starch is not classified as a lipid, distinguishing it from substances like oils and waxes.

Molecules Related to Proteins

• Amino acids are the fundamental molecules related to protein structures.

Structure of Proteins

• Proteins consist of long chains of amino acids.
• The primary structure refers to the linear sequence of amino acids, while the tertiary structure represents the overall 3D shape of a protein.
