The two terminal methyl carbons (of the branch) are numbered 4 and 4′. The amino group is attached to the alpha carbon which is numbered 2. The amino group of valine exists in a protonated form (−NH3+) in normal physiological/biological conditions. Metabolism Valine, being one of the ...

Rather than flattened sacs, the smooth ER consists of tubules and vesicles that branch forming a network. While the tubular shape helps to increase surface area as well, it appears to be well-suited for lipid synthesis and detoxification. ...
Yeah. Well, I could put that on the ends of these corners. That's another possibility. I've got 1. I've got 2. Is there anywhere, any other combination of atoms that I could put these aldehydes on? On the straight chain, no. And on the branch chain, no. So ac...
To model how multiple random variables affect an outcome of an experiment a more complicated branch of statistics, multivariate statistics, is used. To compare these, suppose you are examining the annealing temperature of a DNA PCR primer. Univariate statistics would look how the percentage of one...
polynucleotide chain of deoxyribonucleic acid (DNA)Portion of polynucleotide chain of deoxyribonucleic acid (DNA). The inset shows the corresponding pentose sugar and pyrimidine base in ribonucleic acid (RNA). Other important natural polymers include the proteins, which are polymers ofamino acids, and ...

(R4N+X−). Amines are also classified asaliphatic, having only aliphatic groups attached, or aromatic, having one or more aryl groups attached. They may be open-chain, in which the nitrogen is not part of a ring, or cyclic, in which it is a member of a ring (generally aliphatic)....
Orange double-headed arrow indicates the direction of conformational change of the compound bound to hCA I in comparison to hCA II enzyme. On the other hand, compound 5d differs from compound 15 by the presence of an ethyl -longer chain. This longer chain provides flexibility to the compound...
The condensed structure shows us the connectivity of the molecule. The use of parentheses is important: Parentheses with no subscripts:Branch on the chain. Parenthesis with subscripts:Multiple branches on a chain. CH2within parentheses + subscripts:Repeating CH2units within a chain. ...
