Concept explainers
(a)
To propose:
A reasonable model to explain that exposing a sensory neuron containing TRPV1 to high temperature leads to a sensation of heat.
Introduction:
Neuron is also known as nerve cell is defines as the cell that carries electrical impulses. It serves as the basic unit of nervous system. It is composed of axon, cell body and dendrites.
(b)
To explain:
The few drops of hot peper sauce can taste very hot without actually burning you.
Introduction:
Capsaicin is defined as an active compound of chili peppers produced by plants of genus Capsicum. It is irritant for mammals including humans as it produces a burning sensation in tissues when it comes in contact.
(c)
To determine:
The sensations produced from contact with low and high levels of menthol.
Introduction:
Menthol is an organic compound which is obtained from corn mint, peppermint or other mint oils. TRPM8 is a transient receptor potential cation channel belongs to M member 8 is a type of proteins which is encoded by TRPM8 gene. It is molecular transducer of cold somatosensation in humans.

Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn.

- An orange laser has a wavelength of 610 nm. What is the energy of this light?arrow_forwardThe molar absorptivity of a protein in water at 280 nm can be estimated within ~5-10% from its content of the amino acids tyrosine and tryptophan and from the number of disulfide linkages (R-S-S-R) between cysteine residues: Ε280 nm (M-1 cm-1) ≈ 5500 nTrp + 1490 nTyr + 125 nS-S where nTrp is the number of tryptophans, nTyr is the number of tyrosines, and nS-S is the number of disulfide linkages. The protein human serum transferrin has 678 amino acids including 8 tryptophans, 26 tyrosines, and 19 disulfide linkages. The molecular mass of the most dominant for is 79550. Predict the molar absorptivity of transferrin. Predict the absorbance of a solution that’s 1.000 g/L transferrin in a 1.000-cm-pathlength cuvet. Estimate the g/L of a transferrin solution with an absorbance of 1.50 at 280 nm.arrow_forwardIn GC, what order will the following molecules elute from the column?
