caffeic acid
| acid radical | A radical formed from an acid by loss of one or more hydrogen ions; e.g., SO4-, NO3-. (05 Mar 2000) |

| acid rain | <biology, plant biology> This is rain which has turned acidic because of the presence of sulphur or nitrogen oxides (both created from burning coal and other fossil fuels) in the atmosphere. Acid rain is a serious environmental problem, it can kill trees and harm plants and animals in lakes and ponds. (09 Oct 1997) |
| acid reaction | Any test by which an acid reaction is recognised such as the change of blue litmus paper to red, an excess of hydrogen ions over hydroxide ions in aqueous solution indicated by a pH value less than 7 (at 22캜). Compare: dissociation constant of water. (05 Mar 2000) |
| acid red 87 | Eosin Ys, the disodium salt of 2',4',5',7'-tetrabromofluorescein. Synonym: acid red 87, eosin yellowish. (05 Mar 2000) |
| acid red 91 | The disodium salt of 4',5'-dibromo-2',7'-dinitrofluorescein. Synonym: acid red 91, eosin I bluish. (05 Mar 2000) |
| acid reflux test | A test to detect gastroesophageal reflux by monitoring oesophageal pH by an electrode in the distal oesophagus either basally or after acid is instilled into the stomach. (05 Mar 2000) |
| acid rigor | Coagulation of muscle protein induced by acids. (05 Mar 2000) |
| acid salt | A salt in which not all of the ionizable hydrogen of the acid is replaced by the electropositive element; e.g., NaHSO4, KH2PO4. Synonym: bisalt, protosalt. (05 Mar 2000) |
| acid seromucoid | <biology> Plasma protein of mammals and birds, 38% carbohydrate. In humans a single chain glycoprotein of 39 kD. Increased levels are associated with inflammation, pregnancy and various diseases. (18 Nov 1997) |
| acid soluble spore protein | <molecular biology> A DNA binding protein in the spores of some bacteria, thought to stabilise the DNA in an A configuration, so protecting it from cleavage by enzymes or UV light. (18 Nov 1997) |
| acid stain | <technique> A dye in which the anion is the coloured component of the dye molecule, e.g., sodium eosinate (eosin). (05 Mar 2000) |
| acid sulfate | A salt containing HSO4-. Synonym: acid sulfate. (05 Mar 2000) |
| acid tartrate | A salt of tartaric acid which contains an acid group still capable of combining with a base; e.g., bitartrate. (05 Mar 2000) |
| acid tide | A temporary increase in the acidity of the urine occurring during fasting. Synonym: acid wave. (05 Mar 2000) |
| acid wave | A temporary increase in the acidity of the urine occurring during fasting. Synonym: acid wave. (05 Mar 2000) |
| deoxyribonucleic acid |
The molecule that encodes genetic information. DNA is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T). In nature, base pairs form only between A and T and between G and C; thus the base sequence of each single strand can be deduced from that of its partner.

| deoxyribonucleic acid |
The basic material of life. DNA is a long, chain-like chemical found in the nucleus of all cells. The segments of the chain are the genetic code that guides the development of every cell.

| deoxyribonucleic acid |
The long, spiralling m olecule that rchestrates the cell's daily operations and provides the genetic blueprint for the physical characteristics of all living organisms. When made up of two strands, the strands intertwine like a spiral staircase to form a structure called a doub le helix. Subunits, called bases, are the rungs of the staircase. See also RNA.

| deoxyribonucleic acid |
The nucleic acid molecule consisting of deoxyribonucleotide building blocks that encode genetic information. The genome of most organisms is contained in a double-stranded, double-helical form held together with chemical bonds between each strand of complementary nucleotide base pairs.

| deoxyribonucleic acid |
The long double-stranded chemical molecule found in the nucleus of cells and packaged into chromosomes. DNA contains the "genetic code" (genes) which we inherit from our parents.
