Is aspartic acid hydrophobic?
The hydrophobic amino acids include alanine, valine, leucine, isoleucine, proline, phenylalanine, tryptophane, cysteine and methionine. However, glycine, being one of the common amino acids, does not have a side chain and for this reason it is not straightforward to assign it to one of the above classes.
Any functional groups they contain are uncharged at physiological pH and are incapable of participating in hydrogen bonding. The non-polar amino acids (shown here) include: alanine, cysteine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, tryptophan, tyrosine and valine.
- Was the mutational effect greater in a substitution or deletion? Explain your answer clearely. Deletion; everything gets moved over so everything changes. DNA(sickle hemoglobin is a result of a point mutation in one base), RNA(changes from GAG to GUG), Protein(amino acid level) changes amino acid from GLU to VAL.
- Lipids and Phospholipids. Lipids are fats, like oil, that are insoluble in water. There are two important regions of a lipid that provide the structure of the lipid bilayer. Each lipid molecule contains a hydrophilic region, also called a polar head region, and a hydrophobic, or nonpolar tail region.
- This term arises because hydrophobic molecules do not dissolve in water. If a molecule has areas where there is a partial positive or negative charge, it is called polar, or hydrophilic (Greek for "water-loving"). Polar molecules dissolve easily in water. If a molecule has polar covalent bonds, then it may be polar.
Polar amino acids include serine, threonine, asparagine, glutamine, histidine and tyrosine. The hydrophobic amino acids include alanine, valine, leucine, isoleucine, proline, phenylalanine, tryptophane, cysteine and methionine.
- Describe what makes each of the 20 amino acids found in proteins unique. All amino acids are structurally the same, in that they contain a central carbon atom, an amine group, a lone hydrogen at. The thing that is different about each of the 20 amino acids is the make-up of the R group.
- Non polar side chains consist mainly of hydrocarbon. The non-polar amino acids (shown here) include: alanine, cysteine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, tryptophan, tyrosine and valine.
- Amino acids. Amino acids are the monomers that make up proteins. Specifically, a protein is made up of one or more linear chains of amino acids, each of which is called a polypeptide. Image of an amino acid, indicating the amino group, carboxyl group, alpha carbon, and R group.
