The lipid tails of a phospholipid molecule are hydrophobic, as they consist of nonpolar fatty acid chains that repel water.
the tail ( carbon hydrogen only part) the COOH part that makes it an acid does engage in hydrogen bonding.
Acetyl-CoA is the metabolite that enters the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate through a process called pyruvate decarboxylation.
The hydrophobic tails of the phospholipid molecule are found in the middle of a lipid bilayer. These tails are composed of fatty acid chains that are repelled by water and therefore are oriented towards the interior of the membrane to avoid contact with the surrounding water.
To dilute 18M sulfuric acid to 6M, you would need to use a 1:2 ratio of acid to water. This means mixing 1 part of sulfuric acid with 2 parts of water. For example, you could mix 1 L of 18M sulfuric acid with 2 L of water to get a final concentration of 6M sulfuric acid.
The lipid tails of a phospholipid molecule are hydrophobic, as they consist of nonpolar fatty acid chains that repel water.
COOH, or CO2H, is a 'carboxyl'.
DNA (standing for DeoxyriboNucleic Acid)
No, A sugar molecule has hydrogen and oxygen in it, but it is by no means water. It has to be a separate compound to be considered water.
In the process of photosynthesis, the hydrogen atoms in the water molecule are utilized.
The fatty acid tails of the phospholipid molecule would reject the polar molecule glucose, as the tails are nonpolar and hydrophobic in nature. Glucose is hydrophilic and would not be compatible with the hydrophobic environment created by the fatty acid tails.
The first tRNA molecule leaves behind its amino acid that it was carrying, which is now part of the growing polypeptide chain.
the tail ( carbon hydrogen only part) the COOH part that makes it an acid does engage in hydrogen bonding.
The ionizable part of an amino acid is the amino group, which contains a nitrogen atom with a lone pair of electrons that can act as a proton acceptor or donor. This part of the amino acid molecule can gain or lose a proton, giving it the ability to exist in different ionic forms at different pH levels.
Because of the way the hydrogens bond to the oxygen in water, the molecular geometry is a bent or angular shape, and the oxygen has 2 lone pairs of electrons. This makes the oxygen part of the water molecule rather negative relative to the hydrogen part of the molecule, which is rather positive. Thus, there is a separation of charge, and this is what makes the water molecule so polar.
Mainly The R Group, but also that there is also the particular positions that give the amino acid molecule its characteristic chemical properties. Another is at the -C-C-N- peptide linkage.
When certain molecular crystals are added to water, they are able to dissolve and break down into their original molecules, if they are affected by the interatomic hydrogen bonds that water induces. A simple answer: dissolving.
