The smaller molecules act as building blocks and are called monomer s, and the macromolecules that result from their linkage are called polymer s. Cells and cell structures include four main groups of carbon-containing macromolecules: polysaccharides, proteins, lipids, and nucleic acids. The first three groups of molecules will be studied throughout this chapter.

Hydrocarbons containing a benzene ring are known as aromatic, because many of them are pleasant-smelling. It is amazing to think that nearly all of the hydrocarbons the earth has sequestered in the last 4.5 billion years may be consumed by one species in a matter of a half millennium.Sep 13, 2020 · Contributors. A carbonyl group is a chemically organic functional group composed of a carbon atom double-bonded to an oxygen atom --> [ C=O] The simplest carbonyl groups are aldehydes and ketones usually attached to another carbon compound. These structures can be found in many aromatic compounds contributing to smell and taste. A solid compound of a group 1 (alkali) metal and a group 17 (halogen) element dissolves in water. The diagram above represents one type of solute particle present in the solution.

Dec 24, 2014 · Alcohols contain the hydroxyl functional group and can be primary, secondary, or tertiary. Ethers are compounds with an oxygen atom bonded to two alkyl groups. Aldehydes and ketones contain the carbonyl functional group. In an aldehyde, the carbonyl is at the end of a carbon chain, while in a ketone, it is in the middle. The main reactions of the carbonyl group are nucleophilic additions to the carbon‐oxygen double bond. As shown below, this addition consists of adding a A nucleophilic substitution of an OH group for the double bond of the carbonyl group forms the hemiacetal through the following mechanism
Other types of molecules that contain carbonyl groups are aldehydes, acids, esters, and amides. Ketones. A ketone is a compound whose molecules contain a carbonyl group and have two other groups attached to the carbon atom of the carbonyl group. There are many molecules that belong to this classification, but the simplest one is acetone.

The ketoses have the carbonyl group at any position other than at the end of the carbon chain, examples are dihydroxyacetone (the ketone equivalent of glyceraldehyde), and fructose. The number of carbon atoms in the molecule also is the basis of naming, Another class of organic molecules contains a carbon atom connected to an oxygen atom by a double bond, commonly called a carbonyl group. The trigonal planar carbon in the carbonyl group can attach to two other substituents leading to several subfamilies (aldehydes, ketones, carboxylic acids and esters) described in this section. Alkanones and alkanals together are referred to as carbonyl compounds because they are organic molecules which contain the carbonyl, C=O, functional group: ⚛ Alkanals: C=O occurs at the end of a carbon chain. The general structure of an alkanal is R-CHO (R is an alkane chain or a hydrogen atom)
