The term phospholipid can best be described by which of the following? a) a polar lipid molecule that fully interacts with water b) a polar lipid molecule that fully repels water c) a nonpolar lipid molecule that is made amphipathic by the addition of a phosphate d) a nonpolar lipid molecule that is made polar by the addition of a phosphate
Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.

![You have isolated a previously unstudied protein, identified its complete structure in
detail, and determined that it catalyzes the breakdown of a large substrate. You
notice it has two binding sites. One of these is large, apparently the bonding site for
the large substrate; the other is small, possibly a binding site for a regulatory
molecule. What do these findings tell you about the mechanism of this protein?
a) It is probably an enzyme that works through competitive inhibition
b) It is probably a structural protein found in cartilage or skeletal tissue
c) It is probably a structural protein that is involved in cell-to-cell adhesion
d) It is probably an enzyme that works through allosteric regulation
e) It is probably a cell membrane transport protein, like an ion channel](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F52052328-5a34-4195-86aa-03a6e2c9ba62%2F37cf799a-bf74-402d-968e-35cc2b6422f9%2Fd1f0u6g_processed.png&w=3840&q=75)
