CHEMISTRY GLOSSARY
Results 1–7 of 7 for peptid
peptide bond → peptidna veza
Peptide bond emerges when two amino acid join in a way that the carbon atom from one connects with the nitrogen atom from the other (creating a C-N bond).
peptisation → peptizacija
Peptisation is a process in which coagulated colloid returns into a dispersed state.
isoelectric point → izoelektrična točka
Isoelectric point (pI or IEP) is the pH of a solution or dispersion at which the net charge on the molecules or colloidal particles is zero. In electrophoresis there is no motion of the particles in an electric field at the isoelectric point. The net charge (the algebraic sum of all the charged groups present) of any amino acid, peptide or protein, will depend upon the pH of the surrounding aqueous environment. For example, alanine can have a charge of +1, 0, or -1, depending on the pH of the solution in which it is dissolved.
polypeptide → polipeptid
Polypeptides are peptides containing ten or more amino acid residues. The properties of a polypeptide are determined by the type and sequence of its constituent amino acids.
toxin → toksin
Toxins are effective and specific poisons produced by living organisms. They usually consist of an amino acid chain which can vary in molecular weight between a couple of hundred (peptides) and one hundred thousand (proteins). They may also be low-molecular organic compounds. Toxins are produced by numerous organisms, e.g., bacteria, fungi, algae and plants. Many of them are extremely poisonous, with a toxicity that is several orders of magnitude greater than the nerve agents. Botulinum toxin, produced by the bacteria Clostridium botulinum, is the most poisonous substance known.
Dipeptide → Dipeptid
Dipeptide is an organic compound formed when two amino acids are joined by a peptide bond. Depending on which groups of amino acids are involved in the peptide bond four dipeptides can be formed from two different amino acids. For example, glycine (Gly) and alanine (Ala) can give two symmetrical dipeptides (GlyGly and AlaAla) and two unsymmetrical dipeptides (GlyAla and AlaGly). The naming is done by reading the sequence from the N-terminus to the C-terminus.
