| 2 | Number average molecular weight |
| The number average molecular weight is a way of determining the molecular weight of a polymer... polymers), so we have to take an average of some kind. The number average molecular weight is the common average of the molecular weights of the individual polymers. It is determined by measuring the ... | |
| 3 | DNA ladder |
| A DNA ladder is a solution of known molecular weight markers that is used for electrophoresis gel calibration used to analyse weights of samples ... | |
| 4 | Polydispersity index |
| In organic chemistry, the polydispersity index , or PDI, is a measure of the distribution of molecular weights in a given polymer sample. The PDI is calculated is the weight-average molecular weight divided by the number average molecular weight. As the polymer chains approach uniform chain length ... | |

It is common to run "marker proteins" of known molecular weight in a separate lane in the gel, in order to determine the ... | |
| 8 | Polyethylene glycol |
| Polyethylene glycol and polyethylene oxide are polymers of ethylene oxide. Polyethylene glycol refers to the polymer with molecular weight less than 50,000, while polyethylene oxide is used for higher molecular weights. Polyethylene glycol has the following structure: -(CH2-CH2-O) n- It is ... | |
| 9 | Molecular mass |
| The molecular mass of a substance (less accurately called molecular weight and abbreviated as MW ) is the mass of one molecule of that substance, relative to the molecular mass unit u (equal to 1/12 the mass of one atom of carbon-12). Thus it is a dimensionless number. The molecular mass can be ... | |
| 10 | 5-HTP |
| 5-HTP (5-Hydroxy-tryptophan) is decarboxylated to the neurotransmitter serotonin (5-HT) by the enzyme aromatic-L-amino-acid decarboxylase. It is sold as a mood elevating drug. Chemistry IUPAC name: 5-Hydroxy-tryptophan Chemical formula: C 11 H12 N2 O3 CAS number: 56-69-9 Molecular weight ... | |

| Biotin , also known as vitamin H or B 7 and C 10 H16 N2 O3 S (Biotin; Coenzyme R, Biopeiderm), is a B-complex vitamin which is important in the catalysis of essential metabolic reactions to synthesize fatty acids, in gluconeogenesis, and to metabolize leucine. The molecular weight of biotin is ... | |
| 13 | Bradykinin |
| Bradykinin is a protein of the kinin group of proteins and consists of 9 amino acids. The kininogenase kallikrein make bradykinin by proteolytic cleavage of its kininogen precursor, High-Molecular-Weight-Kininogen(HMWK). It is a potent vasodilator, causes contraction of non-vascular smooth muscle ... | |
