![Page 1: Organic Compounds All living things are made of organic compounds. Contain the element Carbon Carbohydrates, Proteins, Lipids, Nucleic Acids.](https://reader033.fdocuments.net/reader033/viewer/2022061417/551bdf46550346be588b5d00/html5/thumbnails/1.jpg)
Organic Compounds• All living things are made of organic
compounds. • Contain the element Carbon• Carbohydrates, Proteins, Lipids,
Nucleic Acids
