1. acids a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain
5. acid A molecule consisting of the basic amino group (NH2), the acidic carboxylic group (COOH), a hydrogen atom (-H), and an organic side group (R) attached to the carbon atom, thus, having the basic formula of NH2CHRCOOH.
8. a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together.ex: many synthetic organic materials used as plastics and resins
9. a molecule that can be bonded to other identical molecules to form a polymer.
10. a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.

2. any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose.
3. acid Any of the group of a long chain of hydrocarbon derived from the breakdown of fats (through a process called hydrolysis). It has a single carboxylic group and aliphatic tail. 2) sub-units of fats, oils and waxes.
4. An oxygen atom has stronger polarity. Polar atoms interact with water, meaning they are hydrophilic.
6. The basic building block of nucleic acids, such as DNA and RNA. It is an organic compound made up of nitrogenous base, a sugar, and a phosphate group. Supplement.
7. A molecule in which the electrons are shared equally between the nuclei. As a result, the distribution of charge is even and the force of attraction between different molecules is small. Non-polar molecules show little reactivity.
8. A molecule composed of polymers of amino acids joined together by peptide bonds.
11. any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
