Postulate a reason for why so many aliphatic amino acids are essential.
Propose a reason for why so many of the essential amino acids belong in the aliphatic and aromatic groups.
Which of the following amino acids has an aliphatic R group? Which of the following amino acids has an aliphatic R group? tyrosine, leucine ,serine cysteine asparagine
1. Amino acids are often broken down into two groups, essential and nonessential. Essential amino acids must be eaten in order to survive as we don’t make them. This is why intaking a certain amount of protein is so important to the body. In one of the greatest scientific finds of the 21st century, amino acids were discovered inside meteorites that had impacted the earth. Interestly, the amino acids contained different side chains and configurations than those found on earth....
Humans have what are called essential versus non-essential amino acids. There are also "non-standard" amino acids that exist. What is the difference between these groups?
2. Classify the following amino acids as essential or non-essentia ids as essential or non-essential amino acids. b. R c. H d. D e. V f. N g. F h. I i. K j. Q K. A 198
Amino acids can be categorized according to the body's ability to synthesize them. Both essential and nonessential amino acids are necessary for life, but the human body is unable to synthesize some amino acids. Different pathways enable synthesis of nonessential amino acids from five precursors: pyruvate, 3-phosphoglycerate, oxaloacetate, a-ketoglutarate, and phenylalanine. Many of these pathways include a process called transamination, which is a reaction between an amino acid and an alpha-keto acid. Some non essential amino acids are synthesized in...
5. Draw structures of nine essential amino acids.
Which of the following describes conditionally essential amino acids? a) They are always required in the human diet because we cannot synthesize them in adequate amounts b) They are the only amino acids used for protein synthesis c) They are the amino acids that are oxidized for energy d) They are amino acids that may be synthesized, but not when the precursor amino acid is in short supply
Some amino acids such as Ile, Met, and Leu have nonpolar, aliphatic radical groups, while others such as Ser, Cys, Glu, Pro, Asn, and Thr have polar uncharged radical groups. Where in proteins would you expect to find amino acids such as Ile, Met, and Leu but not amino acids such as Ser, Cys, Glu, Pro, Asn and Thr? A.on an outside surface interacting with water B.folded inside a central, core region that does not interact with water C.not within...
