Answer:
<em> e) Ala</em>
Explanation:
Alpha helix is a secondary structure of proteins, it is made of 3.6 aminoacids residues per turn, this structure is possible thanks to local hydrogen bonding between C=O and N-h groups. The result is a cylindrical structure with a hydrogen-bonded backbone and the outside studded with side chains.
Glycin has an -H in its side chain, this makes it a too flexible molecule, therefore it's unusual to find them in alpha-helical structures because their presence could cause the helix to deform. Large R-groups can also affect this stability, phenylalanine has a bulky aromatic side group, this discards it as a stabilizer. Serine has a hydrogen bond donor or acceptor as a side chain, due to the proximity to the main chain it competes with the main chain to form NH and CO bonds. Alanine is the most common amino acid in alpha-helix structures because it has a short and no charged R group (unlike arginine that even when it's short it has a charged R-group), this makes it flexible enough to keep the structure stabilized.
Hope you find this information useful! good luck!
1. the scientific definition of a fruit is a structure that bears a seed or seeds that develops from the ovary of a flowering plant
2. the term for distributing seeds after they mature is called dispersing
3. mechanical dispersal occurs when the ripened fruit opens and scatters seeds
agent dispersal occurs when an animal feeds on fleshy fruits as some seeds pass through the digestive system, while some drop and scatter onto the ground.
hope this helped & god bless

A monohybrid cross determines the allele combinations of offspring for one ... Share incomplete dominance (neither is fully expressed in the phenotype, ... Sex-linked conditions are usually X-linked, as very few genes exist on the shorter Y chromosome.
