5.2: Carbohydrate Structures - Chemistry LibreTexts
WebMar 2, 2024 · Carbohydrates are organic compounds that contain only carbon ( C), hydrogen ( H), and oxygen ( O). They contain a chain of carbons, an aldehyde or a ketone, and hydroxyl groups. Every carbon atom is attached to one oxygen atom. There are thousands of different carbohydrates, but they all consist of one or more smaller units … WebCarbon may be stored for long periods of time in the atmosphere, bodies of liquid water—mostly oceans— ocean sediment, soil, rocks, fossil fuels, and Earth’s interior. … And in all of these you can see the role that carbon is playing.
