Fatty acid are hydrocarbon chains with carboxylic acid at the end. Unsaturated fatty acid contain one or more double bonds, usually in cis conformation. There are two methods of naming the unsaturated double bonds, delta and omega.
Delta naming system:
1. Count carbons starting from the carboxylic end. The total number of carbons in the fatty acid is the first number in the name.
Fatty acids are types of lipids that can be found in many different roles in our body including energy storage.
Fatty acids consist of hydrocarbon chain with carboxylic acid at the end. Thus fatty acids are called amphiphilic (they have both hydrophobic and hydrophilic parts). Fatty acids can be saturated (all single bonds) or unsaturated (have double bonds).
Prion is a misfolded version (wrong secondary and tertiary structure) of prion protein that is transformed to an infectious particle that leads to disease. How does prion come about? Generally, when proteins get misfolded in our body, they are either sent to be repaired or get degraded by protease (an enzyme that breaks down proteins). Prions, however, are resistant to the protease and remain misfolded and undegraded. T...
Which amino acid has the lowest isoelectric focus point?
Isoelectric focus point or pI is the pH at which a protein has no net charge and does not move in an electric field. Isoelectric focus point basically tells us how acidic or basic a protein is. The more acidic the protein is the lower it's pI is. Therefore, looking at the answer choice we must first determine whether these amino acids are ac...
