Study Notes
- Lipids play various roles in the body, including acting as a long-term energy storage, forming cell membranes, and serving as chemical messengers.
- The main components of lipids are triglycerides, phospholipids, and steroids, with most lipids containing glycerol and fatty acids that are hydrophobic and do not dissolve in water.
- Steroids are a class of lipids made up of fused rings of atoms, with cholesterol being the most important steroid.
- Nucleic acids are molecules that contain genetic information in the form of DNA or RNA, consisting of nucleotides that transmit genetic information to the next generation.
- Proteins are polymers of amino acids and serve various functions in the body, such as providing structural support, acting as enzymes, and playing a role in immune responses.
