Which of the following would be a possible amino acid sequence for an oligopeptide given the experimental data below. Give your answer in abc-efg-hij format. 1. The amino acid composition is found to be [tyr, ala, phe, arg, ser and met and some decomposition products]
2. The peptide has a molecular weight around 700 Da and absorbs at 280 nm.
3. Treatment with carboxypeptidase results in phenylalanine and a peptide.
4. First cycle Edmond Degradation yields PTHserine.
5. CNBR treatment yields two tripeptides.
6. Trypsin digestion produces a dipeptide and a tetrapeptide with met on the amino end.
7. Chymotrypsin digestion yields tetrapeptide and a dipeptide.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

i think the answer is c hope this
