A sentence diagram is a pictorial representation of the grammatical structure of a sentence. The term "sentence diagram" is used more when teaching written language, where sentences are diagrammed. The model shows the relations between words and the nature of sentence structure and can be used as a tool to help recognize which potential ...
Alanine (symbol Ala or A), [4] or α-alanine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a methyl group side chain. Consequently it is classified as a nonpolar, aliphatic α-amino acid.
α-Linolenic acid, also known as alpha-linolenic acid (ALA) (from Greek alpha meaning "first" and linon meaning flax), is an n−3, or omega-3, essential fatty acid. ALA is found in many seeds and oils, including flaxseed , walnuts , chia , hemp , and many common vegetable oils .
A sentence, in turn, is formed as a sequence of symbols, beginning with a designated non-terminal symbol and culminating in a terminal string. Every terminal node is part of a constituent, as constituents form the interconnected structure leading from the root to the smallest, indivisible unit of the tree.
The two diagrams thus disagree concerning the status of do, diagrams, show, and do these diagrams show us, the phrase structure diagram showing them as constituents and the dependency grammar diagram showing them as non-constituents. To determine which analysis is more plausible, one turns to the tests for constituents discussed above.
Aminolevulinic acid synthase (ALA synthase, ALAS, or delta-aminolevulinic acid synthase) is an enzyme (EC 2.3.1.37) that catalyzes the synthesis of δ-aminolevulinic acid (ALA) the first common precursor in the biosynthesis of all tetrapyrroles such as hemes, cobalamins and chlorophylls. [1] The reaction is as follows:
With a tree diagram, the sentence's structure can be depicted as in Figure 1. Figure 1 All the points illustrated by circles and diamonds are nodes in Figure 1, and the former are called nonterminal nodes and the latter terminal nodes . [ 2 ]
[1] [2] It contains the now-famous sentence "Colorless green ideas sleep furiously", [3] which Chomsky offered as an example of a grammatically correct sentence that has no discernible meaning, thus arguing for the independence of syntax (the study of sentence structures) from semantics (the study of meaning).
