Study Notes
Compound (Conjugated) Lipids
- Lipids conjugated with other substances, consisting of fatty acids, alcohols, and other groups.
- Classified according to the type of group attached.
Classification of Compound Lipids
- Phospholipids: contain phosphoric acid.
- Glycolipids: contain sugars.
- Sulfolipids: contain sulfate.
- Lipoproteins: contain proteins.
Phospholipids
- Formed from fatty acids, alcohol, phosphoric acid, and ± nitrogenous base.
- Types of phospholipids:
- Phosphoglycerides (Glycero-phospholipids)
- Sphingomyelin (Sphingo-phospholipids)
Sphingomyelin
- Structure consists of:
- Sphingosine base (sphingol, an alcoholic amine)
- Unsaturated fatty acid
- Phosphoric acid
- Choline base
Phosphoglycerides
- Structure consists of:
- Glycerol
- Saturated fatty acid
- Unsaturated fatty acid
- Phosphatidic acid:
- Intermediate compound in synthesis
- No nitrogenous base
- Phosphoric acid
- Phosphatidic acid + choline = lecithin
Nucleotides
- Definition: building blocks of nucleic acid (DNA & RNA)
- Structure consists of:
- Phosphate
- Nucleoside
- Nitrogenous base
- Purines: Adenine, Guanine, Xanthine, Hypoxanthine
- Pyrimidine: Cytosine, Uracil, Thymine
- Pentose sugar: deoxyribose (DNA), Ribose (RNA)
- Types of nucleotides:
- Base Nucleoside
- Adenine: Adenosine
- Guanine: Guanosine
- Xanthine: Xanthosine
- Hypoxanthine: Inosine
- Cytosine: Cytidine
- Uracil: Uridine
- Thymine: Thymidine
- Adenosine Mono, Di, Tri Phosphate
Functions of Nucleotides
- Building blocks of DNA & RNA
- Source of energy: ATP, GTP
- Mediate hormone action: cAMP, cGMP are 2nd messenger
- Co-enzymes: NAD, FAD
- Activation of compounds: UDP-glucose used for glycogen synthesis
- Group donors: PAPS → sulfate donor, SAM → methyl donor
- Synthetic Analogues: 5-flurouracil (Allopurinol), Thymine (Pyrimidine), Hypoxanthine (Purine) used for cancer treatment and gout treatment.
