Melatonin contains several functional groups, including an indole ring, which is a bicyclic structure that features a nitrogen atom. It also has an ethylamine side chain, characterized by an amine (-NH) group and a methoxy (-OCH₃) group. These functional groups contribute to melatonin's biological activity and its role in regulating sleep-wake cycles.
Melatonin is considered a relatively non-polar molecule due to its structure, which includes an indole ring and a hydrocarbon tail. While it does contain some polar functional groups, such as the amine and carbonyl groups, the overall balance of its structure leans towards non-polar characteristics. This affects its solubility, making melatonin more soluble in lipids than in water. Thus, it can be classified as a non-polar molecule with some polar features.
Functional
there are two functional groups in an aldoheptose: hydroxyl and aldehyde.
Vanillin contain as functional groups ether, hydoxyl and aldehyde.
The functional groups of furfural are an aldehyde group and an aromatic ring.
A kenopentose has a ketone functional group attatched to a monosaccharide that contains all hydroxyl functional groups.
The functional groups attached to novestrol are:AlcoholMethylAlkyne
There are several functional groups in Taxol, including ester, benzene ring, hydroxyl, and amide groups.
The main functional groups in butter are esters (found in triglycerides, which make up the majority of the fat content), hydroxyl groups (from glycerol), and carboxyl groups (found in fatty acids). Butter also contains small amounts of other functional groups such as alcohols and aldehydes, contributing to its flavor and aroma.
The functional groups involved in forming disulfide bonds are sulfhydral (-SH) groups.
The functional groups of adenosine include a purine base (adenine) and a ribose sugar. Adenosine also contains functional groups such as an amino group (-NH2) on the adenine base and hydroxyl groups (-OH) on the ribose sugar.
The functional groups present in the infrared spectrum of benzophenone are carbonyl (CO) and aromatic (CC) groups.
