PPT-Carbohydrates Carbohydrates are polyhydroxy aldehydes or ketones, or substances that yield

Most of the carbohydrates have the empirical formula CH 2 On some also contain nitrogen phosphorus or sulfur There are three major size classes of carbohydrates monosaccharides oligosaccharides.

Be able to name alcohols.. Describe the shape of alcohols.. Classify primary, secondary, and tertiary alcohols.. Describe the physical properties of alcohols.. ,-Unsaturated Aldehydes and Ketones. 18-8. Conjugated unsaturated aldehydes and ketones are more stable than their unconjugated isomers.. Enones, or . ,-unsaturated carbonyl groups, are stabilized by resonance.. Before you can learn about aldehydes and ketones, you must first know something about the nomenclature of carboxylic acids since many of the names of aldehydes and ketones are derived from the names of the corresponding carboxylic acids..

Carbohydrates Carbohydrates serve a variety of functions E nergy storage and food Structure and support Lubrication Protection Recognition and signaling Component of nucleotides starch mucin (glycoprotein) Organic compounds. Functional group identification. Many organic compounds contain an atom or group of atoms that substitute for hydrogen or carbon in a basic hydrocarbon.. The atom or group of atoms is commonly referred to as functional group.. Carbohydrates. Are the most common type of organic compound. Examples: Starch or sugar. Is used to store energy.
