| Question | Answer |
|---|---|
| pH of blood | between 7.35 to 7.45 |
| what is the physiological pH? | between 7.2 and 7.5 |
| Acids | 1.a lot of H ions 2.proton donor 3.lower than 7 pH |
| base | 1.removes H ions 2.proton acceptor 3.higher than 7 pH |
| buffers | 1.weak acid ( salt compound ) 2.neutralizes pH 3. |
| important buffer in humans | sodium bicarbonate |
| antacids | neutralizes acids and forms a salt. |
| ratio of carbohydrates | 1:2:1 carbon, hydrogen, and oxygen |
| how many carbon atoms in monochromes | 3-7 ex. glucose, fructose and galactose |
| ratio of lipids | 1:2 Carbon and Hydrogen |
| 5 examples of lipids. | 1.fatty acids 2.Eicosanoids 3.glycerides 4.steriods 5.phospholipds or Glycolipids. |
| Fatty acids. | 1.COOH 2.nonpolar except carboxyl group 3. saturated or nosaturated. |
| saturated fatty acids | no covalent bonds. |
| unsaturated fatty acids | 1.monounsaturated: one double bond 2. polyunsaturated: two or more double bonds. |
| Eicosanoids | from arachidonic |
| exampples of Eicosanoids | 1.Leukotrienes: in immune system 2.Prostaglandins: local hormones short chains of fatty acids. |
| Glycerides | fatty acids attached to glyceral molecule. |
| Triglycerides | 1.neural fats. 2. for energy, insulation, and protection |
| Steroid | four rings of carbon and hydrogen with an assortment of function groups |
| types of steroids. | 1. Cholesterol: component of cell membrane (plasma) 2. Estrogen and testosterone: sex hormons 3. Corticosteroids and calcitriol: metabolic regulation 4. Bile salt |
| what is the amino acid structure | 1.centrol C atom 2.H atom 3.Amino group 4.COOH 5.R group |
| how long is oligopeptide | 2-15 amino acids |
| how long is polypeptide | 15-50 amino acids |
| how long is protien | 50 and more amino acids |
| what is the bond in tetri shape | disulfide bond |
| what is the bond in secondary shape | H bonds |
| examples of fibrous protein | keratin or collagen |
| What are Globular protiens | function is based on shape and are soluble |
| what is in glyco proteins | Large protein + Small carbohydrate |
| function of glyco proteins | promotes viscosity which means lubricants. |
| what is in proteoglycans | Large polysaccharides + polypeptides |
| examples of proteoglycans | hyaluronan and chondroitin sulfate |
