Animal nutrition first 1/3 test
| Term | Definition |
|---|---|
| Sugars | The MOLECULES that the elements carbon, hydrogen and oxygen form in carbohydrates |
| Monosaccharide | Single simple sugar |
| Disaccharide | Two sugar molecules |
| Polysaccharide | More than two sugars |
| Starch | Primary digestible polysaccharide in plants, composed of repeating units of maltose (which in turn was repeating units of glucose), so it is all glucose. Composed of 2 parts. |
| Cellulose | Composed of repeating units of cellobiose, therefore also composed of glucose (primarily). Contains BETA bonds; no animal can digest beta bonds. Beta bond -> structural rigidity, makes fibrous nature of cellulose different from starch. |
| Glycogen | Polysacchride composed of highly branched chains of glucose which is stored in animal cells for a ready supply of energy |
| Glucose | Most important sugar; monosaccharide; hexose; blood sugar |
| Ribose | Pentose; monosaccharide |
| Fructose | Monosaccharide; hexose; found both combined and free in nature; combined with glucose in table sugar; high in semen to support sperm |
| Galactose | Monosaccharide; hexose; only found combined in nature, with glucose in milk |
| Maltose | Disaccharide; 2 units of glucose with alpha bond |
| Mannose | Monosaccharide; hexose; does not occur free in nature but occurs combined in polysaccharides |
| Cellobiose | Disaccharide; 2 units of glucose with beta bond |
| Sucrose | Disaccharide; composed of one unit of fructose and one unit of glucose; table sugar |
| Lactose | Disaccharide; composed of one unit of glucose and one unit of galactose; milk sugar |
| 3 major polysaccharides | Starch, cellulose, glycogen |
| Amylose | Composed of straight chains of glucose without lots of branching; form of starch |
| Amylopectin | Composed of chains of glucose with lots of branching; form of starch |
| Acetic acid | 2 carbons, 0 double bonds |
| Propionic acid | 3 carbons, 0 double bonds |
| Butyric acid | 4 carbons, 0 double bonds |
| Palmitic acid | 16 carbons, 0 double bonds |
| Stearic acid | 18 carbons, 0 double bonds |
| Oleic acid | 18 carbons, 1 double bond |
| Linoleic acid | 18 carbons, 2 double bonds |
| Linolenic acid | 18 carbons, 3 double bonds |
| Arachidonic acid | 20 carbons, 4 double bonds |
