Carbohydrates Practice Cheat Sheet
- Carbohydrates - These macromolecules are made of carbon, hydrogen, and oxygen in a 1:2:1 ratio. They're your primary energy source, powering everything from cell division to brainpower. Think of them as tasty fuel bars for your cells! Learn more on OpenStax
- Monosaccharides - The simplest carbohydrates include glucose, fructose, and galactose, each with a unique flavor and function in your body. They're like the LEGO bricks of sugars, snapping together to build bigger structures. Enjoy the sweet simplicity! Explore monosaccharides
- Disaccharides - When two monosaccharides link via glycosidic bonds, you get disaccharides like sucrose, lactose, and maltose. This dehydration reaction releases water, making it a sweet science experiment in your kitchen! Discover disaccharides
- Polysaccharides - Long chains of monosaccharide units form polymers like starch, glycogen, and cellulose. These giants either store energy for later or build sturdy structures - talk about multitasking molecules! Dive into polysaccharides
- Starch - Plants stack up energy in starch, which is made of amylose (straight chains) and amylopectin (branched chains). It's like nature's rechargeable battery for our favorite veggies and grains. Read about starch
- Glycogen - The animal version of starch, glycogen, is a highly branched glucose polymer stored in liver and muscle cells. It's your body's rapid-response energy stash when you sprint, swim, or dance! Unpack glycogen
- Cellulose - This structural polysaccharide fortifies plant cell walls with β-1,4 glycosidic bonds, making it fiber that we can't digest. It's like the rebar in concrete - strong, supportive, and essential for plant posture! Check out cellulose
- Chitin - Found in arthropod exoskeletons and fungal cell walls, chitin is built from N-acetylglucosamine units linked by β-1,4 bonds. It's nature's tough armor, giving strength and protection to insects and crustaceans. Study chitin
- Glycosidic Bonds - These covalent links form between carbohydrate molecules during dehydration reactions, creating everything from simple sugars to complex fibers. They're the chemical handshake that unites monosaccharides into bigger structures! Explore bonds
- α vs. β Linkages - The orientation of glycosidic linkages (α or β) dictates whether polysaccharides like starch (digestible) or cellulose (indigestible) form. It's all about the flip of a bond - tiny change, huge impact! Learn linkage types
