Definition Thiols are organic compounds with the general structure R-SH. They are sulfur analogs of alcohols (R-OH). R can be aliphatic or aromatic. The simplest aliphatic representative is methanethiol, the simplest aromatic is thiophenol (analogue of phenol). Thiols are formally derived from hydrogen sulfide (H2S), in which a hydrogen atom has been replaced by a … Thiols
Definition Carboxylic acids are organic acids with the general structure R-COOH (less commonly: R-CO2H). It is composed of a residue, a carbonyl group, and a hydroxyl group. The functional group is called the carboxy group (carboxyl group). Molecules with two or three carboxy groups are called dicarboxylic acids or tricarboxylic acids. An example of a … Carboxylic Acids

Structure and properties Lipids are characterized by being soluble in organic (apolar) solvents and generally sparingly soluble or insoluble in water. They have lipophilic (fat-loving, water-repellent) properties. Lipids also exist, with polar structural elements such as the phospholipids or ionized fatty acids. They are called amphiphilic and can form lipid bilayers, liposomes and micelles. For … Lipids

Definition Amides are organic compounds containing a carbonyl group (C=O) whose carbon atom is bonded to a nitrogen atom. They have the following general structure: R1, R2 and R3 can be aliphatic and aromatic radicals or hydrogen atoms. Amides can be synthesized with a carboxylic acid (or a carboxylic acid halide) and an amine using … Amide
Definition Esters are organic compounds formed by the reaction of an alcohol or phenol and an acid such as a carboxylic acid. The condensation reaction releases a water molecule. The general formula of esters is: esters can also be formed with thiols (thioesters), with other organic acids, and with inorganic acids such as phosphoric acid … Ester
