Answer:
Secondary structure
Explanation:
Stricture of proteins can be categories into 4
Primary structure, secondary structure, tertiary structure and quaternary structure.
Primary structure are polypeptide chains. The polypeptide chains are formed by amino acids held together by peptide bonds.
Secondary structure refers to the folding of polypeptides chains. Two most common secondary structures are alpha helix and beta pleated structure. These folding occurs because of hydrogen bonding between the oxygen of the carbonyl of one amino acid and the hydrogen of another amino acid.
Therefore, hydrogen bonding is crucial for secondary structure of the protein.
Answer:
Molar mass= 78.8gmol-1
Explanation:
P= 550torr, V= 0.0732dm3, m= 0.5g , R= 8.314, T= 273+489= 762K
Applying
PV= m/Mm×(R×T)
Substitute and Simplify
Mm= 78.8gmol-1
Hey there!
B + O₂ → B₂O₃
Balance O.
2 on the left, 3 on the right. Add a coefficient of 3 in front of O₂ and a coefficient of 2 in front of B₂O₃.
B + 3O₂ → 2B₂O₃
Balance B.
1 on the left, 4 on the right. Add a coefficient of 4 in front of B.
4B + 3O₂ → 2B₂O₃
Our final balanced equation: 4B + 3O₂ → 2B₂O₃
Hope this helps!
It is photosynthesis
<span>
photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct, hope it helps</span>
