Which part of phospholipd molecule is non polar and hydrophobic?
The hydrophobic portion of the phospholipid molecule is the fatty acid tails. These tails consist of long hydrocarbon chains that do not interact well with water molecules, making them nonpolar and hydrophobic.
The water molecule has a dipole with the negative portion?
located near the oxygen atom and the positive portion located near the hydrogen atoms. This creates a partial positive charge on hydrogen and a partial negative charge on oxygen, making water a polar molecule.
The phosphate portion of a phospholipid is?
The phosphate portion of a phospholipid is hydrophilic, meaning it interacts readily with water due to its polar nature. It is located on the head of the phospholipid molecule, along with other polar groups, forming the hydrophilic "head" of the molecule. This is in contrast to the nonpolar hydrophobic tails of the phospholipid, which cluster together in the interior of cell membranes away from water.
The result of Acrolein Test?
Acrolein test is a test for the presence ofglycerin or fats. A sample is heated with potassium bisulfate, and acrolein is released if the test is positive.[8] When a fat is heated strongly in the presence of a dehydrating agent such asKHSO4, the glycerol portion of the molecule is dehydrated to form the unsaturated aldehyde, acrolein (CH2=CH-CHO), which has the peculiar odor of burnt grease.
When placed between oppositely charged metal plates the region of a water molecule attracted to the negative plate is what?
partially positively charged hydrogen end of the molecule.
What do hydrophobic portion of a synthetic detergent molecule usually consists of?
The hydrophobic portion of a synthetic detergent molecule typically consists of a long hydrocarbon chain, such as alkyl or aryl groups. This hydrophobic tail is responsible for interacting with oily or greasy particles to remove them from surfaces.
The portion of a DNA molecule that describes a complete polypeptide chain is called a?
The portion of a DNA molecule that describes a complete polypeptide chain is called a gene. Genes are specific sequences of nucleotides that contain the instructions for making specific proteins during the process of protein synthesis.
What is an adamantane?
An adamantane is a polycyclic hydrocarbon with a cagelike structure similar to a portion of a diamond lattice.
What molecule is important in the formation of the heme portion of the hemoglobin molecule?
iron
What do soaps hydrocarbon portion and charged portion confer on?
The hydrocarbon portion of soaps allows them to dissolve non-polar substances such as dirt and oil, while the charged portion (either positively charged or negatively charged) enables them to interact with water molecules. This dual nature of soaps allows them to effectively remove dirt and oil from surfaces and emulsify them in water for easy rinsing.
What acts as ATPase during the contraction cycle of muscle?
myosin cross-bridges
Which part of phospholipd molecule is non polar and hydrophobic?
The hydrophobic portion of the phospholipid molecule is the fatty acid tails. These tails consist of long hydrocarbon chains that do not interact well with water molecules, making them nonpolar and hydrophobic.
What is the iron-containing portion of the hemoglobin molecule called?
The iron containing part of hemoglobin is the 'heme' molecule.
What do all lipids have in common a?
At least some portion of the molecule is hydrophobicA+
What describes only the portion of a database available to a particular user?
Subschema
What will most likely happen if there is a change in the first three subunits on the upper strand of a molecule?
A Portion of Molecule 2 may be different
What part of the hemoglobin molecule is recycled to form bile?
A portion of the heme group
