Lesson Summary The Chemistry of Carbon nescient chemistry is the study of compounds with bonds between carbon atoms. Carbon atoms bring in four valence electrons, allowing them to ready strong covalent bonds with galore(postnominal) other(a) elements, including heat content, oxygen, phosphorus, sulfur, and nitrogen. Living organisms atomic number 18 make up of molecules make of carbon and these other elements. One carbon atom provoke bond to another to form chains and rings. Carbon sight form millions of different openhanded and complex structures. Macromolecules umteen of the carbon molecules in living things ar so large they are called macromolecules. Macromolecules form by polymerization, in which smaller units called monomers roast unneuroti c to form polymers. Biochemists sort the macromolecules in living things into groups ground on their chemical composition. Carbohydrates (starches and sugars) are composed of carbon, hydrogen, and oxygen. Carbohydrates are the principal(prenominal) sinew source for living things. Plants and some animals also apply carbohydrates for geomorphological purposes.

Molecules with one sugar monomer are monosaccharides. A disaccharide is made of dickens monosaccharides. Lipids (fats, oils, and waxes) are made mostly of carbon and hydrogen atoms. Lipids whoremonger be used to store energy and form separate of biological membranes and waterproof coverings. Steroids manufactured by the ashes are lipids as well. Nucleic acids c! ontain hydrogen, oxygen, nitrogen, carbon, and phosphorus. They are polymers of base of operationss. A nucleotide has lead parts: a 5-carbon sugar, a phosphate (PO4) group, and a nitrogen-bearing base. Nucleic acids store and transmit hereditary (genetic) information. There are deuce kinds of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Proteins are made up of...If you vitalness to get a full essay, order it on our website: OrderEssay.net
