What are amino acids? Describe their basic parts. What is the importance of the -R group in an amino acid molecule? What are the amino acids required for the protein synthesis? a) Which is the only amino acid that does not have a carbon atom in its side chain? b) Wha...
Much less common than the amino acids mentioned earlier are selenomethionine and selenocysteine, in which the sulfur of cysteine and methionine is replaced by selenium. Approximately 15 proteins (selenoproteins) possessing these selenoamino acids have been described. Selenocysteine is preferably found in ...
Question: What part of an amino acid is always acidic? Amino Acids Amino acids are the small molecules that make up proteins. They have three parts: the amino group (NH2), the carboxylic acid group (C with a double bond to a O and a single bond to an OH), and the R group. Gener...
This chapter will review plasma membrane receptors for amino acids which are or may be neurotransmitters. Our focus will be on the mammalian brain, with brief consideration of simpler animals and peripheral nervous tissue. Although the number of amino ac
Amino acids are bifunctional compounds and the basic structural units/building blocks of proteins. In chemistry, an α-amino acid consists of an amino group, a carboxyl group, an R-group, and a hydrogen atom which is bonded to the α-carbon. The R-group represents a side chain specific to...
A protein is a sequence of amino-acids which forms a long and thin string-like molecule. This string twists and turns to fold into a ball that is susp..Abdellah Salhi
Amino acidsare the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also...
amino acids, which include bioenergetic formation, biosynthetic activity, and resistance to metabolic stress. This review also discusses the regulation of amino acid metabolism in cancer, therapies that are under investigation, and aspects of amino acid metabolism relevant to inhibition with a specific ...
The simplest is glycine, in which the saturated carbon atom is unsubstituted, rendering it optically inactive. The rest of the 20 most common amino acids are optically active and exist as both d- and l-stereoisomers. Naturally occurring amino acids are, for the most part, the l-isomers. ...
Which biological molecules are composed of amino acid subunits? An enzyme is a kind of which molecule? a) Protein b) Lipid c) Carbohydrate d) Amino Acid What is the directionality of lipids, proteins, and carbs? Which of the following macromolecules are made of am...
