Interpretation:
The element should be identified when
Concept introduction:
The periodic table is given below,
Figure 1
The electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.
The Aufbau principle:
The aufbau principle is states that in the ground state of an atom, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. For example, the 1s shell is filled before the 2s subshell is occupied.
The subshell ordering by this rule is

- Which of the following is the correct glycosidic bond linkage of the disaccharide shown? OH но но он Он но но. OH OH O B-(1–1) glycosidic bond O B-(1–6) glycosidic bond O a-(1–6) glycosidic bond O a-(1-1) glycosidic bondarrow_forwardConsider the structure of the tripeptide (in its fully protonated form) below. H H H + I || H₂N-C-C-N-C-C-N-C-C-OH 1 I | H CH₂ H CH₂ CH₂ T C=O OH AA1 0=0 || HC-CH3 CH3 AA2 AA3 0=C 1. Give the sequence of the tripeptide using the ONE-LETTER DESIGNATION (UPPERCASE LETTER) with NO spaces and symbols between each letter. 2. How many ionizable groups are there in the tripeptide? Give the numerical value (e.g., 10 not ten). • pH 10: {Choices: -2, -1, 0, +1, +2} 3. Which amino acid residue has one ionizable group left upon forming the tripeptide? {Choices: AA1, AA2, AA3, none, all} 4. Give the net charge of the dominant structure of the tripeptide at the given pH values. The pK, values of the amino acids are given in Table 1. • pH 4: {Choices: -2, -1, 0, +1, +2}arrow_forward1)Since bromelain is an endopeptidase, what types of bonds does it work on? 2)Since bromelain is an endopeptidase, what types of bonds does it work on?arrow_forward
- Glucose is a reducing sugar while sucrose is a non-reducing sugar. What could possibly be the chemical structure present in a sugar that renders it reducing or non-reducing?arrow_forwardWhich of the following pairs are epimers? xylulose and ribulose ribose and ribulose xylulose and ribose galactose and mannose The correct answer is xylulose and ribulose. Please explain why and how to identify epimer pairsarrow_forwardWhich of the following is the correct glycosidic bond linkage of the disaccharide shown? β-(1→6) glycosidic bond α-(1→6) glycosidic bond α-(1→1) glycosidic bond β-(1→1) glycosidic bondarrow_forward
- (1) Which is an alpha-anomer? (2) Which is a reducing disaccharide and which is a non-reducing disaccharide? (3) Which is open chain form of A?arrow_forwardDefine the term reducing sugar. What structural feature doesa reducing sugar have?arrow_forwardCopper ions present in Benedict’s reagent react with the free end of any reducing sugars, such as glucose, when heated. Originally blue in color, these copper ions are reduced by the sugar and produce an orange-red colored precipitate. Alternatively, iodine-potassium iodide (IKI) may also be used when working with starch. IKI contains special tri-iodine ions which interact with the coiled structure of a starch polymer. Prior to a reaction, the IKI displays a yellow-brown color; however, after reacting with starch, a dark purple or black color is presented. The molecule pictured below produced a blue color when tested with Benedict’s reagent, a yellow color when tested with IKI, and a violet color when tested with Biuret reagent. Based on the structure shown below and these chemical results, what kind of biomolecule is this?arrow_forward
