Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. Each type of organic molecule has its own specific type of functional group. What is the significance of functional groups?įunctional groups are collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties. These functional groups are bound to a hydrocarbon structure denoted R. The types of functional groups include halocarbons, alcohols, ethers, aminoss, aldehydes, ketones, carboxyllic acids and esters. What are the different functional groups?įunctional groups are groups of atoms in hydrocarbons which are responsible for their chemical properties. The male sex hormone testosterone contains ketone, alkene, and secondary alcohol groups, while acetylsalicylic acid (aspirin) contains aromatic, carboxylic acid,… The second functional group found in caffeine is amides, which consists of a carboxyl group directly attached to a nitrogen atom.Ĭapsaicin, the compound responsible for the heat in hot peppers, contains phenol, ether, amide, and alkene functional groups. In caffeine there is one tertiary amine group – the nitrogen atom is attached to 3 alkyl groups and no hydrogen atoms. There are two functional groups found in the molecule caffeine – amines and amides. What functional groups are present in caffeine? Caffeine occurs in tea, coffee, guarana, maté, kola nuts, and cacao. What type of compound is caffeine quizlet?Ĭaffeine, nitrogenous organic compound of the alkaloid group, substances that have marked physiological effects. The caffeine molecule also contains methyl groups (-CH3), carbonyl groups (-C=O), an alkene group (-C=C) and also an imine group (-C=N). So it contains two amine and two amide functional groups that exhibit special properties. So caffeine contains two amine and two amide functional groups.įunctional groups include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl. They are both part of the 5-membered system called an imidazole ring. The C=C and C=N bonds look like functional groups, but they are neither alkene nor imine groups. The two N atoms are part of amine groups. 5 What is the significance of functional groups?ĭoes caffeine contain an amine functional group?.4 What functional groups are in capsaicin?.2 How many amine groups are in caffeine?.1 Does caffeine contain an amine functional group?.
