Final answer:
Glycine is the simplest amino acid with a hydrogen atom as its side chain, making it nonpolar and the only non-chiral amino acid without an enantiomer. Ice must be made from potable (safe to drink) water for food processing operations. This is because impurities and contaminants in non-potable water can affect the quality and safety of the food being processed.
Step-by-step explanation:
The simplest amino acid is glycine because it only has a hydrogen atom as its side chain. This distinguishes it from other amino acids that have more complex side chains composed of various carbon-based groups and functional groups. Unlike all other chiral amino acids, glycine's α-carbon is not chiral because its side chain is a hydrogen atom, which makes it the only amino acid without an enantiomer (mirror-image version of itself). This also affects the chemical nature of glycine, making it nonpolar and non-chiral.
