How do proteins work? How does their structure influence their properties? (a) What are the bonds between the amino acids? (b) What determines how the amino acid behaves? How do the "R" groups of amino acids contribute to the 3-D shape of a protein?
However, if the changed amino acid is in a crucial part of the protein, then the protein may be defective and not work as well or at all; this type of change can lead to disease. Other types of mutations in DNA can occur when small segments of DNA break off the chromosome. These ...
Why does the R group of Serine make it a good amino acid to link to a carbohydrate? Describe the structure and function of carbohydrates, lipids, proteins, and nucleic acids. Why is protein the only macronutrient (fat, protein and ...
While I couldreallytake you back to freshman biology—listing all the amino acids, explaining what each does, and supplying you with a handy mnemonic to memorize them (including “Pvt. Tim Hall” or Phenylalanine-Valine-Tryptophane, Threonine-Isoleucine-Methionine, Histidine-Arginine-Lysine-Leucine :...
collagen and peptides lead to improved moisturization and help strengthen the hair shaft. Recent research also shows that amino acids like lysine, tyrosine, and histidine, when added to shampoos, help repair hair damage by restoring the amino acid balance. Companies are heavily investing in R&D ...
So how does not feeling pain work? First, let's learn a little bit more about the nervous system. Your nervous system is made up of your brain, cranial nerves, spinal cord, spinal nerves, and other bodies, like ganglia and sensory receptors. Your nerves are what carry messages from your...
also known as lipids.In the remaining brain matter, you would find proteins and amino acids, traces of micronutrients, and glucose.The brain is, of course, more than just the sum of its nutritional parts,but each co...

Skin pigmentation resides in the epidermis, or the thin outer segment of the three layers that make up the skin. The epidermis alone is made up of three tiny sub-layers. Pigment does not reach the dermis, the middle layer of skin [source:University of Maryland Medical Center]. ...
Proteins are even more complicated than Go.One estimate is thata reasonably complex protein could, in principle,take any of as many as10 different shapes. The shape which it does eventually settle into is a result ofa balance ofvarious atom-scale forces that act within its amino-acid building...
