5. Classify each of the following amino acids as polar or nonpolar and hydrophillic and hydrophobic. NH2 CH2 CH2 H2N-C-COOH H2N-C-COOH a. b. Polar or nonpolar: Hydrophilic or Hydrophobic:
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
![**Amino Acid Classification**
**5. Classify each of the following amino acids as polar or nonpolar and hydrophilic or hydrophobic:**
**a.**
[Diagram of the first amino acid structure in four parts:
1. A hexagon ring structure with a bond extending down.
2. The bond connects to CH₂.
3. The CH₂ is bonded to a central carbon (C).
4. The central carbon (C) has four connections:
- To the left: H₂N (Amino Group)
- To the right: COOH (Carboxyl Group)
- Below: H (Hydrogen Atom)
- Above: CH₂]
**Polar or nonpolar:** ___________________
**Hydrophilic or Hydrophobic:** ___________________
**b.**
[Diagram of the second amino acid structure in five parts:
1. At the top: NH₂
2. Bonded below NH₂ is a carbon (C) with a double-bonded oxygen (O) pointing upwards.
3. The same carbon (C) is bonded directly below to another CH₂ group.
4. The CH₂ is bonded to a central carbon (C).
5. The central carbon (C) has four connections:
- To the left: H₂N (Amino Group)
- To the right: COOH (Carboxyl Group)
- Below: H (Hydrogen Atom)
- Above: CH₂ with a double bonded oxygen (O)]
**Polar or nonpolar:** ___________________
**Hydrophilic or Hydrophobic:** ___________________
**Notes for students:**
- Polar amino acids have side chains (R groups) that can engage in hydrogen bonding and are often hydrophilic.
- Nonpolar amino acids have side chains typically composed of hydrocarbons, making them hydrophobic.
