13.7.3.6 Arabinoxylans in cosmetics
Arabinoxylan derivatives, such as cation arabinoxylans and their hydrophobically modified products, are potentially useful ingredients in cosmetic and personal care products (Yang, Wuxi, & Cui, 2017). Water-soluble cationic arabinoxylans exhibit hair conditioning properties, and arabinoxylans with low-molecular-weight and high charge density can be absorbed on the hair surface. Cationic polymers are commonly used in hair conditioners as the electrostatic interactions between the positively charged cationic polymer and anionic hair surface lead to the absorption of the conditioner on the hair surface, thus making the hair soft and smooth (Fig. 13.18). Properties such as diverse structure, biocompatibility, nontoxicity, and low production costs make arabinoxylans promising candidates for these uses (US patent 2019).
Explanation:
Nociception can be described as a response to harmful or potentially harmful stimuli (chemical, mechanical, thermal). It includes four stages:
1.Transduction or first phase: A noxious stimulus occurs (injury, burn, incision) and it is transformed into a electrical signal that can be carried via transmission.
2. Transmission or the 2nd phase: the pain signal travels to the central nervous system, first to the spinal cord than to the brain.
3. Perception or the 3rd phase: occurs in the cerebral cortex where the perception of pain is generated (the conscious awareness of a painful sensation).
4. Modulation-last phase: pain message is usually inhibited through this phase.
Answer: The statement is false
Explanation:
NONSENSE mutation, NOT MISSENSE mutation causes premature chain (protein) termination.
Missense mutation is simply a kind of point mutation where a single nucleotide is changed to cause substitution of a different amino acid, thus resulting in a non-functional protein.
So, non-functional protein is caused by missense mutation making the statement false
Proteins are made by ribosomes and then folded into their correct shape inside the endoplasmic reticulum. These proteins are then taken to the Golgi apparatus, or body, to be modified and then placed into little sacs called vesicles to transport the proteins. The two organelles are related in how they are both involved in the assembly and transportation of proteins.
<h3><u>Answer and Explanation;</u></h3>
- <em><u>Decomposers are very important in the return of nutrients from dead organisms and waste back to the ecosystem.</u></em>
- <em><u>Molds break down dead leaves and other plants, enabling the release of nutrients back into the ecosystem.</u></em>
- Decomposers break down the organic matter into simpler compounds. it's very important process because complex compounds that build living organisms are not absorbable for other organisms, thus chemical cycling wouldn't be possible and the whole ecosystem would shut down.
